Navigation apparatus of Global Positioning Systems are wildly used in many applications one of which is attitude determination using global satellite navigation signals. For decision of this task there are used code and phase measurements for radiosignals received at space distribute points. It is known that phase measurements are characterized by ambiguity for resolution of which there are used different methods. Using more perfect method of ambiguity resolution one can get better angel estimation accuracy. In the article there is synthesized effective ambiguity resolution method of combined code and phase measurements using multichannel approach.

Objective. To get more effective algorithm of code and phase ambiguity resolution in a task of attitude determination using global satellite navigation signals.
