In addition, the precursor of the GPS is a meridian satellite positioning system (Transit) developed by the U.S. military, which was developed in 1958 and put into use formally in 1964. The system works with a star network of 5 to 6 satellites, bypasses the earth at most 13 times a day, cannot give altitude information, and is not satisfactory in terms of positioning accuracy. However, the meridian system enables research and development departments to obtain preliminary experience on satellite positioning, verifies the feasibility of positioning by the satellite system and lays a cushion for the development of the GPS. The satellite positioning shows great superiority in navigation and the meridian system has great defects in navigation of submarines and ships. The American sea, land, air and military and civil departments feel urgent need for a new satellite navigation system.
For this reason, the united states Naval Research Laboratory (NRL) proposed a global positioning network project named Tinmation with an altitude of 10000km composed of 12 to 18 satellites, and launched a test satellite each in 1967, 1969 and 1974, on which an atomic clock timing system was preliminarily tested, which is the basis of accurate positioning of GPS. The united states air force proposed 621-B plans with 3 to 4 constellation groups of 4 to 5 satellites per constellation group, all but 1 of these satellites using a slant orbit with a period of 24h, which broadcasts satellite ranging signals based on pseudo random codes (PRN), which are powerful and can be detected even when the signal density is lower than 1% of the ambient noise. The successful use of pseudorandom codes is an important basis on which GPS has been successful. The naval plan is mainly used for providing low-dynamic 2-dimensional positioning for ships, and the air force plan can provide high-dynamic service, but the system is too complex. Since the development of both systems at the same time incurs significant costs and both plans are designed to provide global positioning, in 1973 the united states department of defense united states 2 into one, led by the united satellite navigation and positioning planning office, which was at the lead of the department of defense, and the establishment of a handling agency at the air force space in los angeles. The organization members are numerous, including representatives of the united states army, navy army, department of transportation, the national defense mapping office, the north convention, and australia.
