EBU's New Scrambling
System
The European
Broadcasting Union has developed a simple scrambling system that can work with
all makes of equipment used to transmit and receive digital television pictures
by satellite.
Until now, EBU members and other
broadcasters wishing to receive scrambled signals sent over the EBU's
Eurovision network have had to buy equipment from Tandberg TV (formerly NDS).
In future, they will be able to use equipment made by the manufacturer of their
choice.
Specifications of the Basic Interoperable Scrambling System
(BISS) have been finalised in close collaboration with manufacturers. EBU
Geneva will test the "first-level mode" of this system from 26 March to 7 April
2000, and the specifications are expected to be adopted by the International
Telecommunications Union in September.
Four manufacturers - Thomson
TBS, Tandberg TV, Tadiran Scopus and Scientific Atlanta - will be testing the
system using their own equipment later this month. Tiernan, Digital Vision,
Barco, Divicom, Newtec and Alcatel have also been involved in developing the
system.
The new system is based on the DVB common scrambling algorithm
that is available through the European Telecommunications Standards Institute
(ETSI).
Globalstar USA Launches North
American Service
Globalstar USA has announced the full commercial
availability of its mobile satellite service in the United States. Globalstar
USA is a subsidiary of Vodafone Airtouch Plc.
Globalstar
service is now available throughout the North American continent, including
Canada and Mexico.
Globalstar Canada Satellite Co, the provider of
Globalstar service in Canada, also commenced commercial service this week.
Globalstar de Mexico, Globalstar's service provider in Mexico, already offers
commercial service.
Globalstar USA also announced its international
roaming prices at a base price of US$ 1.79 per minute plus international
charges. This pricing applies to Globalstar USA customers who travel outside
the United States. Currently, roaming is available throughout Canada and
Mexico. Outside of North America, roaming will begin on a region-by-region
basis starting in March, with Brazil and continental Europe.
Globalstar USA offers three distinct domestic pricing plans based on a monthly
service charge and fees for satellite connection and use. The Beyond Basic plan
is US$ 29.99 per month plus US$ 1.69 per minute for satellite airtime. The
Beyond 100 plan is US$ 169.99 per month and includes 100 minutes of satellite
airtime; additional minutes are US$ 1.49. The Beyond 250 plan is US$ 369.99 and
includes 250 minutes of satellite airtime; additional minutes are US$ 1.39.
These prices, which will be offered by Globalstar USA's agents, do not
include international long distance charges. Globalstar USA's resellers will
set prices according to individual market conditions.
Intelsat Voices Concern About
Legislation - and Buys Another Satellite
Intelsat's Board has responded to pending US
legislation by taking steps to convene an emergency meeting of the 143 Intelsat
member nations, and the convening of an arbitration tribunal, for the purpose
of examining the legislation and determining whether such legislation violates
US obligations vis-à-vis the Intelsat Agreements.
If a violation is found to exist, and if no action is taken by the US
Government to remedy the violation, the United States may face expulsion from
Intelsat. Furthermore, the Board instructed Intelsat Management to step up
research of alternative jurisdictions outside of the United States for the
privatised company.
Intelsat's Board has also decided to purchase an
additional NI-Alpha spacecraft from Matra Marconi Space. The original contract
awarded to Matra Marconi Space in January, contained an option for the purchase
of a second spacecraft. This spacecraft, NI-Alpha-2, will be assigned to the
1º W slot serving the Americas, Europe, and Africa, and brings Intelsat's
total spacecraft on order to nine.
Internet Access Using Globalstar
Qualcomm has announced
that it is investigating Internet access and the packet data capability of the
Globalstar Satellite Communications System.
After
successfully completing numerous development tests of packet data for
Globalstar, Qualcomm has announced that the service will be ready for
commercial field trials late this summer, and, followed by a phased
integration, will be available to all Globalstar Service Providers.
The service will allow users in virtually any populated area in the world to
communicate with their corporate data networks and access the Internet, or to
send and receive e-mail messages. Internet access may be accomplished by
connecting a Qualcomm GSP-1600 mobile phone to a laptop computer to access
e-mail and transmit information from virtually any location at data rates of up
to 9600 b/s.
Radyne Comstream Wins US$ 8.6
Million Internet Over Satellite Order
Radyne ComStream has announced that an initial
contract worth in excess of US$ 8.6 million dollars has been awarded by a major
Internet-over-Satellite Internet service provider (ISP). This single order for
satellite Internet infrastructure equipment represents more than 15% of Radyne
ComStream's 1999 revenue in one contract.
The equipment
will be used to continue the wireless Internet service provider's national and
international build-out of its satellite based, wireless Internet service
provider network.
Radyne ComStream is already manufacturing the first
600 units of a total of 1,000 DT 8000 Digital Earth Stations as part of the
original terms of the contract. A Network Management System, and additional
elements within the order, including a suite of custom-engineered solutions for
the client, could potentially increase the value of the contract to an even
higher amount.
Radyne ComStream designs, manufactures, and markets
satellite Internet-infrastructure equipment as well as satellite broadband
modems, multicasting receivers, converters and ancillary products for digital
TV, data and telephone services.
Sinopec Extends NeTrue Vipersat VSAT
Contract
Vipersat
Networks, a division of NeTrue Communications, and the China Petrochemical
Corp. (Sinopec) have announced an agreement to begin development of Phase III
of Sinopec's Corporate VSAT network.
In February 1999,
NeTrue Vipersat Networks Division was awarded the original contract to build a
satellite network to support video, data and voice communications for Sinopec.
The entire project, to ultimately link Sinopec's corporate headquarters and 64
major operating locations within China, is valued at approximately US$ 5
million. The project is to be completed in several phases. With the successful
installation of Phases I and II the two companies are ready to rapidly move
into the next phase of the project.
NeTrue's Vipersat Networks
Division has been a leading developer of VSAT communications solutions for
nearly 20 years. Vipersat produces and markets a line of VSAT communications
products. These products, which are built and optimized for IP (Internet
Protocol) allow the company to quickly develop customisable voice, data, video,
and multimedia solutions for its clients. NeTrue Communications acquired the
Vipersat Networks Division in May 1999.
Synthesiser Patent for Comtech
Comtech Communications
Corporation unit has been issued a US Patent for a "hybrid analogue-digital
phase lock loop multi-frequency synthesiser. The invention, used in Comtech
satellite communications products such as frequency converters and
transceivers, combines the near-theoretical noise floor performance of analogue
phase lock loops with the reliability, insensitivity to temperature variations,
and lower acquisition times of digital phase lock loops.
The digital portion of the newly patented loop eliminates the need for manual
alignment of the synthesiser by a technician, thereby increasing
cost-effectiveness. The analogue portion provides typical C-Band synthesiser
performance 20 dB better than international Intelsat IESS-308 and 309 Satellite
Earth Station specifications. The inherent insensitivity of the digital loop to
temperature variations, along with the long useful life of digital components,
increases reliability in the field. This reduces maintenance, down time and
costs.
Telesat's Monopoly Ends
OnSat.net Canada Inc
has announced that Industry Canada it has been granted approval to use the US
satellite Telstar 5 to provide communication services in Canada, making OnSat
the first communications company in Canada to enter this newly deregulated
market.
Prior to 1 March 2000, Telesat Canada had held a
federally granted monopoly on all Fixed Satellite Services within Canada. In
1999, the government of Canada agreed to open this market to competition.
OnSat is a Canadian company offering Internet via satellite
communications. OnSat holds the exclusive rights to deploy internet
connectivity solutions in Canada using the hub facilities of OnSat Network
Communications Inc in Salt Lake City, USA.
Integral Wins NOAA Operations Centre
Contract
Integral
Systems Inc has won a program definition contract from Lockheed Martin Missiles
& Space to design satellite operations centres for the next generation of
polar-orbiting weather satellites to be operated by the National Oceanic and
Atmospheric Administration's (NOAA) Integrated Program Office.
As a member of Lockheed Martin's National Polar-orbiting
Operational Environmental Satellite System (NPOESS) team, Integral Systems is
responsible for systems engineering of the satellite operations centres, which
consist of primary and backup facilities used for mission planning, monitoring
and control of the NPOESS satellites. Integral will also design the NPOESS
Preparatory Project satellite control centre, which will serve as a risk
reduction demonstration for the NPOESS program.
Integral Systems has
supported US weather satellite programs and their control centers since 1982.
The company serves as prime contractor for the satellite control centres
currently in use by NOAA's Polar-orbiting Operational Environmental Satellite
program and the US Department of Defense's Defense Meteorological Satellite
Program. Integral also is developing the satellite control centre for the next
generation of Geostationary Operational Environmental Satellites as a
subcontractor to Hughes Space and Communications Inc.
The program
definition phase of the NOAA project culminates in March 2002 with the US
government's selection of a single contractor for the NPOESS Engineering,
Manufacturing, and Development phase.
Compton May Be Saved Temporarily
NASA engineers have
identified a means to keep the Compton Gamma Ray Observatory in a safe orbit
even if it suffers further gyro failures.
The Compton
Gamma Ray Observatory was always intended to be safely de-orbited in a
controlled manner at the end of its life, but it has always been assumed that
two of the satellites gyros are required to orient the satellite correctly for
it to enter the atmosphere in a predictable way.
Engineers now believe
that it is possible to use the satellite's thrusters to spin the satellite
allowing other on board instruments to sense the orientation. This would allow
the orientation to be modified prior to re-entry as required enabling the
satellite to remain in orbit until a further gyro fails.
NASA Prices Commercial Access to
Space Station
As a
first step towards the commercialisation of some aspects of the International
Space Station, NASA has published prices for commercial projects on the
station.
NASA's standard package has a price tag of US$
20.8 million, but this does not include a whole string of additional expenses
such as physically getting any experiments or equipment into orbit.
The charge for a one way trip to the space station will be US$ 22,000 per kg in
the shuttle's pressurised area or US$ 26,500 in the unpressurised cargo
bay.
Additional astronaut time costs US$ 15,000 an hour for work
inside the pressurised areas of the space station, extra power costs US$ 2,000
a kilowatt-hour, and extra communication time US$ 100 a minute. No fees are
available for spacewalks.
CPU Tech to Design Next Generation
Space Processor
CPU
Tech is under contract to the Air Force Research Laboratory to do what no one
else has yet been able to do: develop a practical method for adapting
commercial processor designs for use in radiation environments.
Over the next twelve months, CPU Tech will develop RadFire,
a high-assurance, rad-hard equivalent of Motorola's ColdFire processor.
Processors used in space systems such as satellites, payloads and launch
vehicles must be radiation-hardened, very reliable and available for the long
term. If they could also be compatible with commercial grade processors, space
system developers could save a great deal of time and money. They could use
commercially available standard software tools such as programming language
compilers, run-time operating systems and the like, rather than custom
software.
One of the major problems with commercial processors,
however, is that they quickly become obsolete, and therefore unavailable, as
new technology is developed. So a practical solution has to include the ability
for virtually any foundry to manufacture the processor even in the future when
the manufacturing processes may have changed. It also has to include a plan to
ensure the availability of the intellectual property far into the future.
CPU Tech's RadFire will be a high-assurance processor, optimised for use
in radiation environments, that will be the exact functional equivalent of the
ColdFire. It will not become obsolete because its design will be "foundry
process independent." This means that the design netlist can be moved between
foundries without any design changes required. Life-cycle support will be
guaranteed.
Boeing Studies Air Launched
Rocket
A new
air-launch system under development by The Boeing Company and Thiokol
Propulsion could increase US military tactical responsiveness and expand Boeing
civil and commercial launch capabilities.
Designed as a
possible launch system for the US Air Force's proposed Space Maneuver Vehicle
(SMV), AirLaunch would lift approximately 3,000 kg to low Earth orbit (LEO),
with launch-on-demand features at competitive prices. SMV is a small,
un-piloted reusable spacecraft designed to support a variety of military space
missions ranging from satellite deployment to terrestrial and on-orbit
support.
The AirLaunch system is being developed primarily as a
near-term, low-cost, launch-on-demand system for the military, but Boeing also
sees commercial opportunities for the deployment and replenishment of LEO
communications satellites, hypersonic research, remote sensing and technology
development.
AirLaunch also will complement the Boeing launch vehicle
family, which includes the Delta family of expendable launch vehicles, Sea
Launch, and NASA's Space Shuttle, as well as programs that will develop from
the joint NASA/Boeing X-37 program.
The AirLaunch system consists of
two basic configurations. The first would support the military and would be
capable of placing an SMV into LEO. The second configuration would be available
for civil, commercial and military applications using a Conventional Payload
Module.
As a strategic corporate partner with Boeing, Thiokol
Propulsion would provide the AirLaunch solid rocket motors in a multi-stage
configuration. Currently, Thiokol has existing solid rocket motors suitable for
the first two stages and is working on a design that is well matched for the
AirLaunch third stage.
A modified Boeing 747-400F will carry the
AirLaunch vehicle to a predetermined launch altitude. During the launch
sequence the vehicle's wing and tail assembly will provide the necessary lift
and lateral stability until 747/launch vehicle separation is achieved. After
ignition, the launch vehicle wing and tail assembly will be
jettisoned.
Range Safety Halts Taurus Launch
The USAF has postponed
the launch of a Taurus rocket carrying the Multispectral Thermal Imager (MTI)
satellite because of fears that the third stage would fall on an inhabited
island in Tahiti.
The launch from Vandenberg Air Force
Base was originally planned for 28 February but could be delayed for several
weeks. No new launch date has been announced as negotiations to temporarily
relocate the island's inhabitants progress.
When the launch was
planned the island was thought to be uninhabited, however the Tahitian
government has recently informed the US that this is not so. If the residents
will not leave the island for the launch, the launch trajectory will have to be
changed imposing a delay of a month or more as the Taurus launcher would have
to be dismantled to reprogram its flight computers.
The Taurus
launcher will carry the Department of Energy's Multispectral Thermal Imager
(MTI) satellite which will collect images of the Earth in 15 bands ranging from
visible to far infrared light at a precision previously only achieved in the
laboratory, testing technologies that could be used on future imaging
satellites.
MTI also carries a secondary experiment, the High-energy
X-ray Spectrometer (HXRS) which is a joint US-Czech project. HXRS will study a
rare type of solar flare that is thought to trigger high-energy particle storms
that can endanger spacecraft and astronauts.
US Army Develops Safer Rocket
Fuel
The US Army
has announced that it has developed of a safer rocket fuel.
The CINCH (Competitive Impulse, Non-Carcinogenic Hypergol)
fuel has been demonstrated for use in launchers that currently use Aerozine-50,
a carcinogenic hypergolic fuel.
The new fuel reacts on contact with
nitrogen tetroxide or inhibited red fuming nitric acid and is designed to work
in low temperatures. Theoretical calculations show that CINCH will work better
than RP-1 when with hydrogen peroxide or liquid oxygen. Preliminary evaluation
of the fuel was conducted at Marshall Space Flight Center with further
demonstration projects at Marshall and Edward Air Force Base planned.
3M has a pilot plant producing CINCH for commercial applications.
The
development of CINCH was funded by the Army Acquisition Pollution Prevention
Support Office.

New PLLs for Commercial Space
Applications
Peregrine Semiconductor Corp has introduced the first
products in two new families of high-performance phase-locked loop (PLL)
devices that provide precise frequency synthesis capabilities for commercial
satellite communications.
The PE9600 and PE9700 PLL
family devices feature greater than 10 dB in phase noise improvement and
one-tenth the power consumption of competitive devices, making them ideal
replacements in existing designs and the clear first choice in new designs.
Peregrine also announced that the PLL circuit core used in the new devices is
available as a building block for customer-defined devices.
The PE9600
devices operate at up to 2.2 GHz and are combined with an external prescaler to
generate the LO (local oscillator) signals required by satellite communications
transceivers. The prescaler typically divides the required LO signal frequency
down to 1.4 GHz, placing it within the operating frequency of the PE9600
low-phase-noise PLL. The PE9700 devices operate at up to 3.0 GHz, and are
intended for newer designs, eliminating the external prescalar function and
reducing the parts count and cost of a frequency synthesiser board.
The PE9600/PE9700 chips are fabricated in Peregrine's patented UTSi(R)
(Ultra-Thin Silicon) CMOS process technology, which utilises a synthetic
sapphire substrate that is a pure insulator, rather than semiconductor. As a
result, they provide excellent RF performance, and easily surpass the rad-hard
(radiation-hardened) requirements for reliable operation in commercial
satellites. The PLLs are immune to single-event latch-up (SEL), have
single-event upset (SEU) of less than 10(-9) errors per bit/day, and offer
total-dose radiation tolerance of 100 krad.
Initially, each of the new
product families contains two ICs. The PE9601 and PE9602 operate at 2.2 GHz,
and the PE9701 and PE9702 operate at 3.0 GHz. All of the devices feature a
10/11 dual-modulus prescaler, counters and a phase comparator. The counters are
programmable through either a serial or parallel interface, and can also be
directly hard-wired. Two of the PLLs, the PE9601 and PE9701, have an on-chip
charge pump, while the PE9602 and PE9702 have an up/down output to drive an
external charge pump.
The PE9600/PE9700 PLLs are offered in a 44-pin
CQFJ (ceramic quad-flat-pack, J-lead) package at a price of US$ 2500 each in
quantities of 100 for fully flight-screened devices. Sample quantities are
available now, with volume production planned for early in the third
quarter.
