The United States upgrades transform force to protect GPS " gold surveyor's pole " position

American audit arrange published a report to point out this year in May, system of location of American whole world (GPS) increasingly ageing, extended active duty, foreground can care. Nevertheless, american army and defense industry public figure express at the beginning of this month, the United States is undertaking to GPS modernization is transformed, be in what can foreknow to will come, GPS will still be satellitic navigation domain " gold surveyor's pole " .

Launch the 2nd acting satellite next year

GPS is American army the navigation of a satellite that in 20 centuries 70 time develop serves a system, at the beginning of developing, use at martial end only, turn extensively later into c dog stairs best buy ivil, busin dog stairs and ramps ess to use, the domain such as scientific research.

Navigation of headquarters of air force spaceflight and controller of time service system wear captain of dimension · Ba Keman to say, the U.S. Army shows the satellite that level still is transforming GPS and ground control equipment, to GPS dependability need not be anxious.

Headquarters of air force spaceflight introduces, american plan launchs model to be satellite of the improvement of 2F the 2nd acting dvd discovery best buy GPS in next year, it is the satellite of the 3rd acting GPS of 3A at launching t the best selling dog stairshe first model 2014. Satellite of the 3rd acting GPS shows level to already completed initial design, predict to left factory 2012.

12 satellites extended active duty

Report of American audit office points out, if need to assure GPS dependability, the dependability prep above that must make 24 satellites move normally at the same time 95% , but as a result of many satellites already extended active duty, discard as useless possibly at any time, accordingly, come from 2010 2014, GPS dependability will under 95% , have 80% possibly even only.

This one report caused great attention inside global limits. memory card digital cameras

The 2nd space commands direct of satellite of direct and responsible GPS and pilot air force squadron controller Lieutenant Colonel tells Dianna Bert reporter of Xinhua News Agency, at present has 12 satellites because of extended active duty key be includinged pays close attention to list.

dvd discovery Precision will raise 0.63 meters

Losk Heed - the main contractor that company of Martin spaceflight system is GPS satellite and carrier rocket. At present, this company already signed the agreement that produces satellite of two the 3rd acting GPS with American the best selling dvd discoverydepartment of defense, design project predicts to was finished Spring 2010.

Degelisi says this company vice president, the fixed position precision of dvd discovery 4 satellite of the 3rd acting GPS will raise 0.63 meters from 4 current meters, intensity of ability of its interference rejection, signal and enclothe limits to all rise somewhat.

Civil signal passageway is added reach 4

Satellite of the 3rd acting GPS will provide civil signal not only, and passageway of will civil signal increases to 4.

Degelisi says, the United States and European Union and Japan also come to an agreement, satellite of new generation GPS will with the European Union " Galilean " the implementation of QZSS navigation system of system and Japan is compatible.

American army plans, in future upgrade quickly for GPS inside 5 years transform project infuse capital 5.8 billion dollar. Global location system of future will be mixed by 12 the 2nd acting satellite 32 the 3rd acting satellite is formed.
