SYSTEM FOR DETERMINING POSITION OF GROUND BASED USER Russian patent published in 2012 - IPC H04B7/185 

Abstract RU 2444130 C2

FIELD: information technology.

SUBSTANCE: navigation satellites (1) are at least partly controlled by at least three control satellites (from 3.1 to 3.3), lying at high orbits, inclined relative to the equator (E). Said high orbits intersect with the equatorial plane on an intersecting diametrical straight line (from 5.1 to 5.3) such that two external intersecting diametrical straight lines (5.2, 5.3) an angle on the longitude (2θ), equal to at least 90°.

EFFECT: design of a system for ground based position finding, which enables to cut the number of control satellites at high orbits.
