Comsat Receives US$ 5.5 Million for
Aircraft Modems
Comsat Laboratories has announced the signing of a US$
5.5 million contract with Matra Marconi Space UK Limited in which COMSAT will
design and build satellite communications modem platforms.
The specialised modem platforms will utilise Comsat's own
Commercial Off-the-Shelf (COTS) technology and will be specifically designed
for use in on board aircraft to send and receive voice and data speeds up to 2
Mb/s. Matra Marconi Space UK Limited and Comsat will jointly develop hardware,
software and firmware for customised aircraft applications.
COMSAT
plans to start shipping the modem platforms in late May 2000 and complete the
contract by the end of 2001.
DTV Plus and Microspace Demonstrate
Broadcast of IP Over Satellite and HDTV
DTV Plus, provider of datacasting via digital
television and satellite-based technologies; and Microspace Communications
Corporation, provider of satellite-based video and high-speed data networks for
businesses, demonstrated a breakthrough in datacasting technology. In a
historical first, an IP Multicast stream containing both video and web sites
was sent over a combination of satellite and digital television signals.
DTV Plus is one of the first vendors to showcase its ability
to multicast IP content, using satellite and DTV signals via Microspace and the
Center for Datacasting Innovation (CDI), which was formed by Intel and KICU-TV
in Silicon Valley, California.
IP Multicast is an open, IETF standard
that enables efficient bandwidth usage for applications that distribute data to
multiple recipients. Unlike traditional bandwidth-hungry "unicast," which
creates a separate, point-to-point data stream between the sender and each
receiver, multicast sends a single stream of data that can be accessed by any
recipient desiring the information.
EBU - 50 Years Old
Based in Geneva, and
now grouping 69 national broadcasters from every country in the European
broadcasting area, the EBU celebrates its 50th anniversary on 12 February.
The EBU operates the Eurovision and Euroradio networks,
organises the exchange of news items and sports programming, co-ordinates
co-productions (including the Eurovision Song Contest and cartoon series for
children), pursues technical development and standardisation, provides legal
advice, training and strategic information for its members, and defends public
service broadcasting.
The Eurovision network, using up to 30 digital
channels on Eutelsat's W3 satellite, handled more than 100,000 TV transmissions
in 1999 for EBU members and non-members. Most foreign TV news pictures seen in
Europe reach viewers' TV screens after being offered by EBU members to each
other free of copyright through 12 news exchanges every day. The network also
has permanent links to North America and Asia.
The Euroradio network,
which uses two satellite channels, carries around 2,000 concerts and operas,
400 sports events, and 120 major news events each year. In 1998 the EBU
launched Euroclassic-Notturno, the first inter-broadcaster European music
channel scheduling only classical music, and a new unit called Eurosonic aims
to become a major player in popular contemporary music.
The EBU
Presidency will mark the 50th anniversary with a meeting at the hotel in
Torquay, England, where the Union was founded at a conference hosted by the
BBC.
FAA Extends Comsat Contract
Comsat Corporation has
announced that its mobile communications business unit received a five-year
extension for satellite services supporting the Federal Aviation
Administration's space-based aircraft navigation system.
With this extension, Comsat Mobile Communications will continue to provide
satellite capacity and communications for the Wide Area Augmentation System
(WAAS). This agreement expands the previously announced US$ 57 million contract
between Comsat and the FAA and has an estimated additional value of up to US$
24 million.
WAAS operates in conjunction with the Global Positioning
System. WAAS Reference Station Facilities collect data from the GPS network,
which is then processed and transmitted directly to the aircraft through
Comsat's ground stations and satellite service. The system allows aircraft to
receive these highly accurate positioning signals during all phases of flight -
from take off to landing. Aircraft operating in US airspace use WAAS to enhance
navigation capabilities. The system improves aircraft position accuracy
resulting in more direct routing of aircraft, savings of time, fuel and money,
and improvement of approach and landing safety.
Comsat provides
capacity through specialised transponders on the Inmarsat-3 satellites in the
Atlantic Ocean Region-West and Pacific Ocean Region. Five earth stations, built
specifically for WAAS and operated by Comsat, support this service. Long term
testing of WAAS with the Inmarsat satellites is currently underway.
First Successful Live Multicast to
the Desktop and Wireless LAN Laptop
American Multiplexer Corporation (AMC) has announced
that it has successfully delivered live multicast programming, including
customer content, utilising the Internet and satellite over its fully
integrated terrestrial and satellite network.
The
company is finalising the details to roll out its new multicast services to
hundreds of thousands of potential sites in the US, which is a major
breakthrough in the industry for the delivery of IP broadband services.
AMC has created and is presently rolling out an interactive, multimedia
communications network that utilises IP data and video multicast technology
over a fully integrated terrestrial and satellite network.
The company
specialises in content delivery, dedicated Web-based application hosting and
caching services. AMC services include VPN solutions that enable an
organisation to securely and reliably communicate with its offices, mobile
sales force, business partners, vendors and customers.
Globalstar Opens Twelfth Gateway
Globalstar Northern
Europe has officially opened a new gateway in Karkkila, Finland, now extending
the range of Globalstar's mobile satellite telephone service across Scandinavia
and the Baltic nations. As part of the opening ceremonies, the first official
phone call handled by the new gateway was made by Mr. Olli-Pekka Heinonen,
Finland's Minister of Transportation and Communication.
The Karkkila installation becomes the twelfth gateway to initiate operations in
the continuing roll-out of Globalstar service around the world. It joins
existing gateways in France and Italy to provide coverage across virtually all
of Europe. The new gateway will continue to be used to support friendly user
trials over the next several weeks. Full commercial service from this gateway
will be introduced, initially in Finland, in early April.
Globalstar
Northern Europe, which is the provider of Globalstar service in seven northern
European nations, is a joint venture between Radiolinja Group of Finland and
Elsacom of Italy. Radiolinja Group includes some of the leading mobile
telephone services in northern Europe. Oy Radiolinja Ab, the group's Finland
division, is the leading cellular service provider in Finland and was the first
company in the world to offer commercial GSM cellular service. Elsacom, based
in Rome, is a Finmeccanica company specializing in the provision of fixed and
mobile satellite telecommunication services and will provide Globalstar service
in 27 countries.
Hauppauge and Europe Online Work

Provider.
Herley Receives SPOT Contract From
Matra Marconi
Herley Industries Inc has, announced that it has been
awarded a contract from Matra Marconi Space of France to design and manufacture
a transponder for the SPOT 5 satellite.
Herley will be
providing technology that will allow various SPOT ground facilities to monitor
the exact location of the satellite as it maintains a sun-synchronous orbit at
an attitude of more than 830 km.
The SPOT (Satellite Pour
l'Observation de la Terre) Earth observation satellite system was designed by
CNES (French National Space Centre, Toulouse, France), in co-operation with
Belgium and Sweden, to provide geographic information about regions of interest
anywhere on earth. The image information will be used to generate and update
topographical maps, urban planning, rural development and
telecommunications.
Herley Industries Inc is a microwave technology
company, providing sophisticated components and systems for the
defence/aerospace, satellite launch and commercial markets
world-wide.
Listening for Mars Polar Lander
After two sessions of
observations by radio telescopes in the Netherland, the United Kingdom, Italy
and California there is no confirmation of contact with the lost Mars Polar
Lander.
The radio telescopes used were at Westerbork in
the Netherlands, Jodrell Bank in the United Kingdom, Bologna in Italy and at
Stanford University in California.
Observations were made on Friday
February 4 and on Tuesday February 8. Although the data collected during the
observations has been analysed extensively there is no indication of any
transmissions from the spacecraft on Mars. Analysis is continuing with a final
report due next week.
Kompsat Starts Returning Science
Data
Eight weeks
after its launch on December 20 from Vandenberg Air Force Base in California,
the Korean Multipurpose Satellite (KOMPSAT) has started sending science data to
its ground station in Taejon, Korea.
KOMPSAT, known in
Korea as Arrirang I, is in a 685 kilometer, sun-synchronous orbit at 98 degrees
to the Earth's equatorial plane.
Developed by Korean Aerospace
Research Institute (KARI) and Korean industry jointly with TRW Inc, KOMPSAT
carries three science instruments. These include two instruments built by TRW
for remote sensing applications and a space physics instrument package built by
the Korean Advanced Institute of Space & Technology for characterising the
space environment.
KOMPSAT's primary payload instrument is an
electro-optical camera (EOC), which has started to provide images for the
production of digital elevation models of the Korean peninsula. The models will
be used for topographical disciplines, such as land development planning,
monitoring floods, avalanches and landslides, archaeological surveys and
hydrological studies. The EOC is a pan-chromatic camera with 6.6 meter
resolution.
The second instrument is an ocean scanning multispectral
imager (OSMI). OSMI data will be applied to biological oceanography, such as
the detection of red tides, producing a fish finding map and tracking global
changes resulting from pollution, studying land vegetation and monitoring sea
fog and yellow sand in the Yellow Sea around Korea. OSMI has six spectral bands
and one kilometer resolution.
In addition, KOMPSAT is carrying a space
physics sensor that includes a high-energy particle detector and an ionosphere
measurement sensor. These instruments will enhance the understanding of how the
space environment affects microelectronics and spacecraft.
SOHO Discovers 100th Comet
Calculations completed
today confirm that a comet spotted by a Lithuanian astronomer on 4 February is
a previously unknown object, making it the 100th comet discovered with the SOHO
spacecraft.
Launched four years ago as a project of
international co-operation between the European Space Agency and NASA, the
Solar and Heliospheric Observatory (SOHO) has revolutionised the science of the
Sun. It has also revealed an amazing number of kamikaze comets plunging into
the solar atmosphere, which help to make SOHO the most prolific comet finder in
the history of astronomy. But SOHO-100 is an ordinary comet, and so are two
others that have appeared in the past few days.
Like nearly all of
SOHO's discoveries, the 100th comet showed up in images from the LASCO
instrument. This is a set of coronagraphs that view the space around the Sun
out to 20 million kilometres, while blotting out the bright solar disk with
masks. Developed for SOHO by a multinational team led by the US Naval Research
Laboratory, LASCO watches for mass ejections from the Sun that threaten to
disturb the Earth's space environment. Comet discoveries are a bonus.
SOHO's experts spot many of the comets as soon as the images come in. But still
pictures and movies from LASCO are freely available on the Internet to
astronomers around the world, who can discover less obvious comets without
leaving their desks. This was the case when Kazimieras Cernis of the Institute
of Theoretical Physics and Astronomy in Vilnius, Lithuania, found
SOHO-100.
The Smallest Satellites Ever
Engineers from The
Aerospace Corp. have established two-way communications with the smallest
satellites ever released into orbit.
The two
picosatellites (MEMS-1 and MEMS-2) measure 10 x 7.5 x 2.5 cm, weigh about 0.23
kg each and are attached together by a tether. In passes over the ground
station at Menlo Park, California, on Monday evening and Tuesday morning, the
engineers received data and transmitted commands.
It was confirmed
that the tethered satellites were released Sunday evening from their "mother"
satellite, OPAL (Orbiting Picosat Automated Launcher), which was built by
Stanford University students. OPAL was launched, along with JAWSAT, from a
Minotaur converted ICBM on 27 January.
As part of a series of unique
experiments, the picosatellites communicated via a low power RF link to each
other and with a ground station to exchange information obtained from a series
of simple on-board circuits. The circuits, which were developed with DARPA
funding, were used to test the reliability of microelectromechanical systems
(MEMS) in space as well as probe the low-earth orbit environment. The satellite
networking was accomplished using extremely low cost digital cordless telephone
technology modified for data communications and networking by Rockwell Science
Center technical staff.
The mission ended on Friday when the tiny
satellites ran out of battery power.
The picosatellites were designed
and built by The Aerospace Corp, El Segundo, California, under funding from
DARPA, the Defense Advanced Research Projects Agency. The Aerospace Corp tested
and integrated the satellite components and conceived the mission. The
picosatellites are considered a link toward slightly larger and more
sophisticated nanosatellites envisioned as tiny space workhorses of the
future.
The Aerospace Corp. is an independent, non-profit company that
provides objective technical analyses and assessments for national security
space programs and other space programs in the national interest.
Proton Launch Ban Lifted
Kazakhstan has lifted
its ban on Proton launches from the Baikonur cosmodrome, permitting the
February 12 launch of an Indonesian Garuda satellite.
Proton flights were suspended last October following the break up of a Proton-K
booster just after launch which scattered debris over a wide area of sparsely
inhabited country. Launches of other vehicles were allowed to continue.
Russia will now be able to continue profitable commercial launches and to
launch the controversial Zvezda module for the International Space Station. The
launch of Zvezda is now planned for mid July.
The Russian government
has agreed to pay US$ 370,000 compensation for the damage and clean up
operation following the October Proton failure.
Range Safety by Satellite
A Lockheed Martin-led
team has successfully demonstrated the tracking and terminating of the flight
of space launch vehicles from a central site and through the use of
satellites.
The intention is to eliminate the costs
associated with the network of flight termination system antennas and personnel
that operate them to ensure range safety during launches. Eliminating down
range equipment could save millions of dollars annually in operations and
maintenance costs. Currently, range safety officers use the network to command
the destruction of rockets that stray outside the safe area avoiding
endangerment to property or the public.
Lockheed Martin's space-based
Flight Termination System (FTS) can track just-launched booster rockets from a
central location and send destruct commands to them if necessary, eliminating
the need for a costly network of ground-based tracking antennas at sites far
down range of the rocket's path. The FTS concept can replace the existing
20-year-old, UHF-based flight termination system with a high frequency, digital
signal processing operation, and has the potential to save millions of dollars
in costs.
Using the signals transmitted from a launch vehicle, a
reliable and safe two-way communications link is established through a tracking
satellite, such as NASA's Tracking Data Relay Satellite System, enabling ground
operators to monitor the vehicle throughout the space launch, and terminate the
vehicle if it strays off course. The FTS experiment demonstrated that a
reliable communications link with a space vehicle can be maintained from a
centralised command and control site, through the use of satellites.
Russia Sets Zvezda Launch Date
The Russian Aviation
and Space Agency has announced that the next component of the International
Space Station to be launched will be lofted between July 8 and 14 from Baikonur
by a Proton launcher.
The 19,000 kg Zvezda will provide
the living quarters for the crew, life support systems, electrical power
distribution, data processing systems, flight control and propulsion.
Zvezda has a solar-array wingspan of 30 m and a length of 13 m. It contains
three pressurised compartments and four docking ports.
Globalstar
Launched: 8 February 2000
Site: Cape Canaveral
Air Station, Florida, USA
Launcher: Boeing Delta II (Delta 7420)
Orbit:
LEO, apogee: 915 km, perigee: 900 km: inclination: 52°
International
Number: 2000-008A/B/C/D
Name: Globalstar (4 satellites)
Owner:
Globalstar
Contractor: Space Systems/Loral
Globalstar has
successfully launched four low-earth-orbiting (LEO) satellites, providing
on-orbit back-up capacity for the company's global mobile telephone system. The
company's space segment is now complete with 48 operating satellites supported
by four spares.
Fregat/Dumsat
Launched: 8 February 2000
Site: Baikonur, Kazakhstan
Launcher: Soyuz-Fregat (SL-04)
Orbit: LEO,
altitude: 600 km
International Number: 2000-009A
Name: DUMSAT
International Number: 2000-009B
Name: FREGAT
This launch is a
test flight for the FREGAT upper stage which can carry a payload of up to 3,810
kg to a 1,410 km orbit. After five orbits FREGAT was returned to Earth using
the innovative Inflatable Re-Entry and Descent Technology (IRDT) developed by
Dasa and Lavochkin. FREGAT carried an 110 kg instrumentation package, DUMSAT,
(developed by Dasa) which was deployed shortly before re-entry; this package
was also equipped with an IRDT unit.
The FREGAT IRDT packs into a 1
cubic metre unit when stowed which is inflated using helium to a diameter of
about 8 m just before re-entry to protect the upper stage. Once through the
main heating phase of re-entry, the heat shield is inflated further to about
twice its earlier diameter (14 m) to act as a parachute and an impact cushion.
Landing speed is estimated to be 50 km/hr without a parachute. The IRDT concept
was originally conceived as an effective way to land a probe on Mars in a 1996
Russian mission.
Unfortunately, after an apparently successful
re-entry and descent, it proved difficult to locate either the vehicle or the
instrumentation package. This was due to the failure of the positioning beacons
and bad weather in the search area in the Russian steppes south of the city of
Orenburg in the southern Ural Mountains. Early reports indicate that the
instrumentation package has been recovered.
Astro-E
The M-V-4 rocket failed to place the Astro-E
Japanese/US X-ray spacecraft in orbit on Thursday, falling to earth before it
had completed even one orbit, destroying the satellite in the process.
The main instrument on the US$ 105 million satellite was the X-ray Spectrometer
(XRS), developed jointly by NASA's Goddard Space Flight Center and Japan's
Institute of Space and Astronautical Science (ISAS). The XRS was intended to
measure the heat created by individual X-ray photons, enabling a precision
approximately 10 times greater than with previous X-ray sensors. The XRS would
have been cooled to only 0.060 degrees Kelvin to achieve this accuracy.
The M-V-4 rocket and its payload was launched from the Kogoshima Space
Centre on the southern tip of the Japanese island of Kyushu on February 10.
The first stage suffered a malfunction causing an out of tolerance
attitude error which the second and third stages could not correct. Japanese
officials are blaming a crack in the first stage engine nozzle for the
failure.
Shuttle Radar Mapping Mission
Launched: 11 February 2000
Site: Kennedy Space Center, Florida
Launcher: Space Shuttle Endeavour,
STS-99
Orbit: altitude: 233 km: inclination: 57°
International
Number: 2000-010A
Name: Space Shuttle Endeavour with Shuttle Radar
Topography Mission (SRTM) payload
Owner: NASA
Contractor: see below
The current shuttle flight will make a map of the Earth using the onboard
radar system. It is supposed to make the most accurate maps of the entire Earth
to date. Endeavour will spend 11 days in orbit making elevation measurements of
the Earth's surface. The Shuttle Radar Topography Mission (SRTM) will use a
measurement technique called interferometry to gather 3-D images of
approximately 70% of the Earth's landmass (between 60° N and 56° S).
The primary customer for this information is the US Department of Defense.
Other applications include: flood control, soil conservation, reforestation,
volcano monitoring, earthquake research, glacier movement monitoring, improved
understanding of water drainage, more realistic landscapes for flight
simulators, prime locations for cell phone towers, navigation safety and even
improved maps for backpackers.
In order to gather these images, two
antenna have been extended: one in the orbiter's payload bay and the other from
the end of a mast extended 60 meters out from the Shuttle. This 60 m carbon
fibre reinforced plastic mast, which took 17 minutes to crank out on Friday
evening is the largest rigid structure ever flown in space. The resulting
three-dimensional images will generate the most complete topographic map of the
Earth's land surface ever produced.
SRTM is a joint project between
NASA, the United States National Imagery and Mapping Agency (NIMA), the German
Aerospace Centre (DLR) and the Italian Space Agency (ASI). NASA's Jet
Propulsion Laboratory (JPL) developed the C-band Spaceborne Imaging Radar and
DLR developed the X-band Synthetic Aperture radar (X-SAR). Dornier
Satellitensysteme GmbH, a corporate unit of DaimlerChrysler Aerospace (Dasa),
is the prime contractor for the X-SAR system.
Endeavour's crew
consists of Commander Kevin Kregel; Pilot Dom Gorie; and Mission Specialists:
Janet Kavandi, Janice Voss, Mamoru Mohri (NASDA) and Gerhard Thiele
(ESA).

ICO Begins to See the Light, Iridium
Sees a Glimmer
ICO
Global Communications has announced that Craig McCaw's Eagle River Investments
LLC has started the second round of investment in the satellite company.
ICO can now access US$ 275 million in funding. This follows
on from the first round funding of US$ 225 million which was released in
December. A further US$ 700 million in exit financing will probably be
completed by the middle of the year.
Following this second round of
financing, ICO has signed memoranda of understanding with Hughes Space and
Communications and NEC, which would modify the existing agreements with these
vendors
ICO is in the process of being rebranded as a global Internet
service provider and is dropping its ambitions to be just a mobile telephony
service. The new plan would still require the launch of six satellites which
will deliver a range of Internet and IP-based services to a variety of fixed
and mobile terminals, and not just the mobile voice services that ICO was
originally designed to provide.
Opinion is divided on whether ICO will
need to make major modifications to its fleet of satellites, the first of which
is due for launch mid March. It has been reported that the ground stations will
require modifications to handle packet-switched as well as circuit-switched
traffic.
The refocusing of ICO appears to be part of greater strategy
by McCaw to make ICO a pre-Teledesic, allowing Teledesic more time to develop
into a second generation broadband service provider.

Tracking Antenna Makes Two Way
Internet Access a Reality for Mobiles
TracVision G4, the new KVH Industries Inc, system for
identifying and tracking Digital Video Broadcasting (DVB) satellite signals,
represents an important milestone in the company's drive to provide both global
television access and mobile two-way Internet capabilities.
TracVision G4 is the first single-antenna system designed to
receive and decode signals from a range of DVB-compatible and DSS satellites
and transponders, and then automatically identify, acquire and track the one
selected by a mobile user. At the push of a button, TracVision G4 can
automatically acquire and track a user's new selection.
One commercial
customer reports that two-way Internet through the new Astra Europe Online
system `works perfectly' and showed `excellent performance' with the TracVision
G4, successfully downloading 10MB files in 3.2 minutes.
Stabilization
is critical to maintaining satellite contact in marine applications where the
platform often is subjected to continual pitch, roll and yaw. KVH's TracVision
products have demonstrated the ability to provide continual reception even in
rough seas, which makes the TracVision G4 ideal for a wide range of vessels,
from high-speed powerboats to large luxury yachts and commercial vessels. The
TracVision G4 radome is 50 cm high and 49 cm in diameter.
The new
high-end TracVision G4 also includes the award-winning KVH GyroTrac sensor,
which provides earth-referenced heading data for faster satellite acquisition
and reacquisition. GyroTrac's patented three-axis gyro sensor delivers
stabilised heading output that can be integrated with all onboard electronics
to enhance autopilot and radar performance. A universal interface allows
GyroTrac to provide precision heading data to other onboard navigation
systems.
