SIS has contracted SSL to design and build the highly-capable satellite servicing spacecraft vehicle to meet the needs of the US Defense Advanced Research Projects Agency (DARPA)'s Robotic Servicing of Geosynchronous Satellites
(RSGS) programme, which is designed to inspect, repair, relocate and augment geosynchronous satellites
and plans to include a refuelling payload to extend the life of satellites that are low on propellant.
DARPA has selected one of the major subcontractors for the project, called Robotic Servicing of Geosynchronous Satellites
That will help scientists understand the effect of solar activity on the Van Allen belts, which can grow to cross the orbits of geosynchronous satellites
during strong geomagnetic storms.
The space rock flew well below geosynchronous satellites
, which orbit 22,236 miles (35,786 km) above Earth, but well above the 220-mile (354-km) altitude of the International Space Station.
The time to reach a satellite footprint is significantly less than when geosynchronous satellites
were used, said Chudosky.
However, the asteroid will not pass near the main belt of geosynchronous satellites
in 2029, and the chance of a collision with a satellite is exceedingly remote," it said.
These corrections are broadcast via three geosynchronous satellites
to the GPS receiver, enabling precise real-time navigation without the need for a ground base station.
That's because the scientists and engineers who designed the newest generation of geosynchronous satellites
phased out that channel, which was originally used to detect moisture at low altitudes in Earth's atmosphere.
The MUOS space segment will consist of a constellation of geosynchronous satellites
and the ground segments will include ground stations providing command and control of the satellites, the user network and the ground-based interfaces that provide access to terrestrial telecommunication networks and the Global Information Grid.
Broadband geosynchronous satellites
employing millimeter-wave systems planned for deployment as early as 2002 promise to bring broadband coverage to all parts of the world.
By combining Orbital's experience building industry-leading small low-orbit and geosynchronous satellites
with General Dynamics/Spectrum Astro's work on advanced medium-class spacecraft, our company has now produced, or is currently developing, 148 satellites for over 35 separate customers in the U.
DARPAs new Robotic Servicing of Geosynchronous Satellites
(RSGS) program intends to answer that question by developing technologies that would enable cooperative inspection and servicing in GEO and demonstrating those technologies on orbit within the next five years.
