FIELD: physics, instrument engineering.
SUBSTANCE: invention relates to radio communications and can be used for a satellite positioning system. For this, the receiver position installed on board of the mobile object is assessed based on the navigation signals transmitted by the satellites and received by the antenna array mounted on the mobile object, and the three-dimensional geographic map is used to deduct geometrically the number of multi-trajectory propagation with reflection off the building walls present in the appropriate medium surrounding the receiver on the basis of the receiver position and the ray tracing starting from the receiver. Thus the determined number of trajectory propagation reflected is used to initialize the angle estimation algorithm of propagation thereof allowing to deduct the ray corners reflected off the walls before reaching the receiver.
EFFECT: invention provides a more efficient evaluation of the direction signal receipt.
