Abstract. The orientation will be characterized by the Euler-Krylov angles of the 3-turns of the coordinate system associated with the satellite interferometer placement object relative to the base coordinate system, for example, geocentric. In this case, the unknown measured parameters are the direction cosines of the navigation satellites relative to the associated coordinate system. An algorithm for the operational high-precision measurement of the orientation of a mobile OR with a reduced search for the resolution of phase ambiguity is proposed. The reduction of the search is achieved due to the redundancy of the bases, including virtual ones, with a specific configuration of a sparse antenna array of 4 emitters. A constellation of 3 satellites is sufficient for measurements. Quantitative data on the accuracy and reliability of the measurement are obtained on a statistical simulation software model.

Purpose. To propose an algorithm for rapid orientation determination in an angular navigation equipment and a sparse antenna array configuration of 4 emitters.

Results. Formulary description of the algorithm. Quantitative data on the accuracy and reliability of orientation measurements at different error of estimating the phase difference. Configuration of the antenna array.

Practical significance. The results obtained can be used in the design of the satellite angular navigation equipment of mobile placement objects.
