The USAF launched the Navy's navigation technology satellite Nts 2 from Vandenberg AFB on an Atlas F booster into a 12hr circular orbit of 63° inclination at about 11 600mi altitude. First of a system to be called NavStar, the Nts 2 carried two cesium-beam time standards (atomic clocks) to produce precise time signals and 14 solar-cell experiments for its builder, the Naval Research Laboratory. The joint service NavStar system upon completion would consist of 24 satellites (8 in each of 3 circular-orbit planes) to provide users with longitude, latitude, and altitude information around the clock in any weather. It would give a customer his location within 33ft, his speed within about 4in/sec, and the correct time. Uses of NavStar would include tactical missile navigation and precision delivery of weapons; aid to space, air, land, and sea travel; grid mapping and geodetic surveys; aerial rendezvous and refueling; and search-and-rescue operations. The USAF had announced plans to launch five of its own satellites later in 1977 and 1978 for NavStar testing.
