SIGNAL RECEIVER OF CONSUMER EQUIPMENT OF GLOBAL SATELLITE NAVIGATION SYSTEMS Russian patent published in 2018 - IPC G01S19/13 

FIELD: navigation system.

SUBSTANCE: invention relates to the field of navigation on signals from spacecraft (SC) of global navigation satellite systems (GNSS). Technical result is achieved due to the fact that in the receiver of GNSS signals, the group delay time (GD) of the SC GNSS GLONASS and GPS spacecraft signals is measured, the GD measured is taken into account in the software of the navigation equipment consumers (NEC), and the GPS signal receiver of consumer equipment comprises an antenna assembly, an analog highway of navigation signal processing of satellite navigation systems (AHNSP SNS), a reference generator, an input unit of calibration signal, a signal processing and control unit (SPCU), as well as a calibration system (SC) containing a frequency-generating device (FGD) and a phase increment measuring device (PIMD). At the same time, the SNA ATOS is configured to receive GLONASS and GPS signals simultaneously, the SPCU is configured to control the operation and the frequency plan of the SC, the FGD is made with forming M calibration signals and N heterodyne signals at different frequencies, the PIMD is made by the phases difference of the calibration signals and GPS spacecraft signals selected in such a way that at adjacent frequencies the change in the phase differences of the calibration signals for which the group delay is to be determined does not exceed modulo values π and, in addition, the difference in adjacent frequencies was minimal.

EFFECT: achieved technical result is an increase in the determination accuracy of navigation measurements and parameters.
