with arm robot vehicle recovery satellite concept map
according to the American airlines weekly site, the defense advanced research projects agency (darpa) program in 2016, implemented a program called & other; Phoenix & throughout; Plan for a robot autonomous flight of aircraft from the waste of the spacecraft orbit retired aircraft antenna, and reinstall the new communication system, reconstruction which has the function of using geostationary communication satellites. The benefits of this program is clear: if you can try to reuse those already orbiting obsolete equipment, rather than a new satellite launch, which will greatly reduce the cost of military satellite, but to do this, need significant advances in technology, can be realized in synchronous orbit and beyond the orbit of robot autonomous operation.
according to the report, the $350 million NASA TRDS – K is an obvious example data relay satellite, the satellite is equipped with two 4.9 m diameter not fold parabolic antenna, in January 2013, use & other; Hercules V” Launch, the launch costs up to $200 million. & other; Launch cost depends on the size of the antenna, the antenna size is larger, the higher the cost, if we can use of existing resources, can greatly reduce cost. Throughout the &;
usually communication satellite fuel and solar battery life up to last 15 years, but the defense advanced research projects agency (darpa) think antenna structure can maintain more than 100 years. They think that if dismantling and task modules by installing new production low cost way to retrofit existing antenna, can significantly reduce the cost of satellite communication services, and for the additional equipment, can use the opportunity of commercial satellite launch a lift. A service robot spacecraft will be launched into synchronous orbit, while task modules and other additional devices are packaged on commercial satellite launch tools. Each year into geosynchronous orbit commercial satellite launch as many as 10 to 15 times, that is to say, at least once a month the chance of a ride.
task module synchronous geo-stationary satellites will throw out according to the instructions on the ground, and then the robot vehicle receives and be saved, and then fly to abandoned spacecraft orbit, and the target spacecraft rendezvous, waste will meet up robotic aircraft task module is installed on the discarded vehicle antenna, antenna will be removed, then drag the synchronous orbit, become a new satellite.
beginning in July 2012 the implementation of & other; Phoenix & throughout; Plan at a cost of $180 million, is currently in steady progress, the researchers are testing a few prototype system, including the robot manipulator system, antenna strut mechanical cutting system and safety rendezvous and close service for all kinds of precision sensors. According to the report, & other; Phoenix & throughout; Plan in the first stage is mainly to give old antenna new functions, to rebuild a small antenna 1-5 meters in diameter, and then use it for radio communication, demonstration phase does not pull the antenna into geosynchronous orbit. & other; Phoenix & throughout; The prospects is broad, the United States is currently about 500 retired aircraft, of which 140 have is suitable for the aerial transformation.
