Miami-Dade Fire Rescue Selects MSV's Services for New Command-Post Vehicles
(11 August 2003) The Miami-Dade Fire Rescue Urban Search and Rescue (USAR) team, one of only two U.S. fire-rescue organisations that support the government's international emergency disaster relief efforts, has selected Mobile Satellite Ventures' voice and radio-dispatch services as a component of its new command vehicle design.

A pioneering satellite phone user and veteran Mobile Satellite Ventures (MSV) customer, Miami-Dade Fire Rescue will equip their new state-of-the-art tactical command vehicles with MSV voice, data and radio dispatch capabilities.

Operating on a push-to-talk principle, MSV's two-way, wireless Dispatch Radio Service covers North and Central America, the Caribbean, parts of South America, and up to 250 miles offshore. MSV operates the largest North America network for radio dispatch services supporting up to 15 talk groups from any one terminal. The MSV network includes two geo-stationary satellites and ground stations in Reston, Virginia., and in Ottawa.

The Miami-Dade Fire Rescue USAR team includes rescue specialists, structural engineers, K-9 unit handlers, hazardous material experts, medical personnel, and logistics staff, who are deployed to earthquakes, hurricanes, plane crashes and other disasters across the United States and internationally each year.

Earth Observation

Space Imaging to Conduct Wildland Fire Risk
(14 August 2003) Space Imaging's Wildland Fire Risk Assessment System (WFRAS) approach has been selected by the Southern Group of State Foresters (SGSF) to support ongoing fire management planning and wildland fire risk analysis in each community, county, congressional district and fire response zone of the organisation’s 13 states. The member states are Alabama, Arkansas, Mississippi, Florida, Georgia, Kentucky, Louisiana, Virginia, Texas, Tennessee, South Carolina, North Carolina, and Oklahoma. The organisation also includes the US Forest Service's Region 8 Office in Atlanta. The Texas Forest Service is administering the project on behalf of SGSF.

Space Imaging's WFRAS is a proven wildland fire risk assessment methodology that employs both GIS and remote sensing technologies. It is a well-defined and repeatable process for describing fuels and analysing wildland fire risk to suit any scale of operation, including wildland and wildland urban interface areas. The wildland fuels are mapped using 30-meter resolution Landsat imagery as a baseline. Optionally, high-resolution multi-spectral imagery from Space Imaging's Ikonos satellite may be used for mapping fuels for specific areas of interest. To develop the methodology, Space Imaging worked with leading fire subject matter experts to incorporate the best wildland fire science available for fire protection planning. The Wildland Fire Risk Assessment Model contains calculations to derive indices of Wildland Fire Susceptibility, Fire Effects, Fire Response Accessibility and Wildland Fire Risk. This award follows successful completion of the statewide Florida fire risk assessment project by Space Imaging.

The contract period is initially for 12 months to conduct the baseline analysis, beginning in July 2003. Once the Southern Group of State Foresters Southern Wildfire Risk Assessment project is completed, each state will be better equipped to communicate wildland fire risks to the public. Additional years are planned to ensure proper technology transfer occurs with State representatives.

NovAtel to Develop GPS Differential System to Validate Speed Records
(12 August 2003) NovAtel Inc has been selected by The Institute of Navigation (ION) and the National Aeronautic Association (NAA) to develop a GPS differential system for use by the NAA in establishing straight course speed records for aircraft in flight. The system is expected to be complete by May 2004.

One of the primary functions of the NAA is to encourage, co-ordinate, document and promote competition and record-making aviation and space events in accordance with the rules prescribed by the Federation Aeronautique Internationale (FAI), of which NAA is the official US representative. The FAI Sporting Code requires a 0.25% overall system accuracy in the measurement of record speed over a three-kilometre course. As speeds increase and the time to traverse the three-kilometre course decreases, it becomes impossible to assure the required 0.25% system accuracy using hand-timing techniques. Overall, as aircraft performance improves, the measurement of these types of records becomes equipment and manpower intensive. A GPS system could significantly reduce the equipment costs and manpower currently required for these records.

The ION is a non-profit professional society dedicated to the advancement of the art and science of navigation. It serves a diverse community including those interested in air, space, marine and land navigation and position determination. The Satellite Division of the ION, which is supporting this effort, encourages the development, operation and use of navigation and position determination systems incorporating satellite-based elements.

The Chairman of the NAA Contest and Records (C&R) Board, Stan Nelson, added, "The technology that the NAA C&R Board has been using for flight test speed measurements over the past several decades has not kept pace with advancements in aeronautic designs and materials. We are moving away from the use of high speed photographic and optical timing systems with millisecond timing at best, to the use of space-based satellite systems and carrier phase processing, like the system NovAtel is developing, which should provide microsecond course time measurement precision."

The NAA is the national aero club of the United States. Its primary mission is the advancement of the art, sport and science of aviation and space flight by fostering opportunities to participate fully in aviation activities and by promoting public understanding of the importance of aviation and space flight in the United States.

Launch Services

Another Sea Launch for XM Satellite Radio
(11 August 2003) Boeing Launch Services Inc (BLS) has announced a contract with XM Satellite Radio for the launch of the XM-4 satellite on a Sea Launch rocket in 2006.

The new contract is a direct arrangement between XM Satellite Radio and Sea Launch Company LLC. Sea Launch successfully placed the first two XM satellites, "Rock" and "Roll" in orbit in 2001. The company also was selected for the launch of the XM-3 satellite in 2004 as part of a delivery-in-orbit contract with Boeing Satellite Systems, the manufacturer of all four satellites.

The new contract, signed on August 5, directs the Sea Launch team to deliver the powerful Boeing 702 spacecraft to geosynchronous transfer orbit for a final orbital position at 115° W in support of XM's on-going service requirements. The XM-3 spacecraft will be positioned at 85° W.

Designed for a 15-year lifespan, the Boeing 702 model spacecraft will each generate 18 kW of total power at the start of life in orbit. Alcatel Space, of Toulouse, France, is providing the high-power, S band, Digital Audio Service (DARS) payloads for all of the XM spacecraft.

SpaceX Successfully Fires Falcon Rocket Upper Stage Engine
(11 August 2003) Space Exploration Technologies Corporation (SpaceX) has announced the successful test firing of the Falcon rocket's upper stage engine, called Kestrel. The liquid oxygen and rocket grade kerosene powered engine, which has a vacuum thrust of 7500 lbs, achieved reliable ignition and stable combustion.

In the early weeks of testing, the engine achieved an efficiency of 94.8%, which is higher than many production rocket engines. As a basis for comparison, the Saturn V F-1 engine achieved 93.5%. An ultimate efficiency of approximately 96% and vacuum specific impulse of 325s are expected.

The Kestrel engine is capable of multiple restarts in vacuum for precise placement of one or more spacecraft, and is designed both for high fuel efficiency and light weight. When combined with the advanced aluminium-lithium tank structure, the result is among the industry's best performance for a pressure fed rocket stage while maintaining substantially lower costs.

Space Exploration Technologies (SpaceX) is developing a family of launch vehicles intended to reduce the cost and increase the reliability of access to space by a factor of ten. Falcon, the initial launch vehicle from SpaceX, is developed from the ground up, including both engines, all structure, avionics and launch pad operations. It is capable of over 1400 lbs to orbit in the standard and over 4500 lbs to orbit in the heavy configuration. The privately-developed Falcon is approximately 80% reusable, which will make it the only semi-reusable launch vehicle in the world apart from the Space Shuttle, which is 90% reusable.
