METHOD OF GROUP NAVIGATION OF MOVING OBJECTS Russian patent published in 1999 - IPC

FIELD: navigation, differential subsystems of satellite radio navigation systems. SUBSTANCE: increased precision of determination of position in differential subsystem of satellite navigation system is achieved due to insertion of two auxiliary navigation objects in agreement with known method of group navigation of moving objects and to allowance for additional correcting information from auxiliary navigation objects while computing coordinates of main navigation object in addition to correcting information coming from control and correction station. Known methods of group navigation do not take account of dependence of changes of precision of radio navigation field on relative positions of control and correction station and main navigation object. Proposed method of group navigation approximates field of errors of differential subsystem with due account of navigational information received from control and correction station and two auxiliary navigation object separated in space. EFFECT: increased precision of determination of position in differential subsystem of satellite radio navigation system. 4 dwg
