摘要

The GPS/GLOSNASS navigational user equipment is used by launching carrier rocket as means of external (inspection) trajectory measurements. There are regarded measuring results obtained from specific type of navigation user equipment, developed by MDB "Compass". There is adduced content of data received to information-computing center of spaceports by means of radio-telemetry system. There are analyzed dynamic errors, which appear at stage separation; errors caused by angular motion of diversity antenna of receiver; peculiarity of receiving of navigational signals by turning of launch vehicle and in this connection switching between receiver's antennas. There are compared kinematics trajectory parameters, determined by data of on-board navigational equipment GPS/GLOSNASS and by data of ground-based control tracking radars.
