METHOD DETERMINING ORIENTATION OF OBJECTS IN SPACE, RANGE TO THEM AND BEARING, POSITION COORDINATES AND COMPONENTS OF VELOCITY VECTOR BY NAVIGATION RADIO SIGNALS OF SPACECRAFT OF SPACE RADIO NAVIGATION SYSTEMS

摘要

FIELD: radio navigation. SUBSTANCE: method is based on relative measurements and determinations whose positive feature consists in usage of measurement and determination errors of systematic character that can be compensated. Second specific feature of proposed method making it feasible to raise precision of navigation measurements and determinations lies in the fact that measurements of range increments are measurements equivalent to measurements by linear interferometers placed in orbits of navigation satellites whose bases are measured intervals determined by time marks of time scales of navigation satellites and transmitted in composition of navigation messages of satellite radio navigation signals. Third specific feature of method lies in solving of navigational problem in vector navigation field. Solving of navigational problem in vector field makes it possible to exclude important source of errors related to geometric factor determining position of objects. Proposed method makes it feasible for users of satellite radio navigation systems to determine simultaneously orientation of objects in space, range and bearing to them, their position coordinates and components of velocity vector by way of reception of navigation signal from one navigation satellite in time sequence from two or more positions of it in orbit. EFFECT: increased precision in determination of positions of objects. 4 cl, 4 dwg
