HIGH ELEVATION ANGLE SATELLITE SYSTEM FOR NORTHERN AND SOUTHERN HEMISPHERES, COMMUNICATION METHOD UTILIZING THE SYSTEM, POSITION MEASURING SYSTEM UTILIZING THE SYSTEM, AND METHOD FOR DESIGNING ORBIT

摘要

PROBLEM TO BE SOLVED: To provide a satellite system capable of obtaining a high elevation angle in each service area and improving the application efficiency of each service area even when the longitudes of respective service areas in a medium longitude area of the northern and southern hemispheres are different. ;SOLUTION: A satellite existing on an inclined synchronous elliptic orbit that an orbit inclination is ≥30° and ≤65°, the longitudinal positions of near points and that of far points exist near an approximate equator and the argument of a certain near point is 0° or 180 is used.;COPYRIGHT: (C)2001,JPO
