摘要: Currently, the GPS program is in the full-scale engineering and development phase. During this phase, a constellation of five to six satellites is being maintained to support testing so that the operational effectiveness of the GPS concept for both military and civilian users will be verified. The buildup of the operational constellation will begin in late 1986 and will take approximately two years to complete. Even though the system is not fully operational, several potential civilian applications exist.
