INFO 3: Military Satellites in U.S. Navy and Air Force

[ibnuasad]

In the U.S., military satellites have a big impact on the Air Force and Navy. Just recently, the U.S. Air Force started building powerful electronic cameras to scan skies and calculate, automatically, motions of all satellites that enter their fields of view. These new systems of satellites, can detect fainter objects and analyze orbital maneuvers by satellites in minutes, whereas photographic techniques require a minimum of an hour and a half. Also, military satellites play a big role in the U.S. Navy. The U.S. Navy has just developed a Navigation Satellite System(NNSS). It has been developed initially for ballistic(Of or relating to projectiles, their motion, or their effects)missile submarines for use in their updating of the inertial navigational system. However, it has also been extended for ships. This was made assessable because now high accuracy fixes several times a day can be retrieved on every point on the Earth with the help of this new Navy Navigation Satellite System. NNSS is passive and uses low-orbit satellites to function.
