Аннотация: The purpose of this work is the development of error estimation algorithms in angular orientation determination from satellite radio-navigation systems signals. The values of object angular orientation parameters, in particular, azimuth and elevation angle, can be represented as results of the indirect measurements, with which direПоказать полностьюct measurements are the phase shifts values of the navigation spacecraft signals of global navigation satellite system, taken by spaced interferometer antennas. In this case, for the error estimation in the angular orientation determination the known method of the error estimation in the indirect measurements may be used. One of the results of the conducted investigations is development of the error estimation algorithm for azimuth and elevation angles, based on the known values of the phase measurements errors covariance matrix. The results of calculating the errors in the determination of angular orientation for the assigned constellations of navigation spacecraft with different distances between interferometer antennas are presented.
