【 摘 要 】

In the article, the theory of optimal filtering ofinformation processes is used to synthesize optimal one-stage estimation algorithmfor the object orientation angles using the signals of the satellite navigationsystem. The article also provides equations of optimal filtering, as well astheir representation in the form of the tracking system comprising of anorientation angles discriminator and a smoothing filter. The synthesizedalgorithm has no tracking systems for the phases of the received signals (orphase differences) and the procedures for resolving the ambiguity of phasemeasurements that enhance its noise immunity while maintaining high precisionin estimating the orientation angles. The article provides expressions for thecalculation of the Cramer-Rao lower limit for the dispersion errors matrix forestimating object orientation angles when receiving signals of an arbitrarynumber of navigation satellites. The results of the simulation of thesynthesized system are provided in the study.
