Zusammenfassung:	Disclosed is an adaptive receiver configured to receive signals from satellite navigation systems to determine receiver coordinates and configured to use a co-op tracking system to evaluate full phases of carrier phases for N navigation satellites in view. The adaptive receiver includes channels with autonomous wideband phase lock loops (PLLs) in a guiding status. The wideband PLLs are configured to track phases of carrier signals from satellites having high SNR and configured to produce control codes for target designations of varying carrier frequency. The adaptive receiver also includes channels with narrow-band PLLs in a guided status. The narrow-band PLLs can track phases of carrier signals of satellites with low SNR and are configured to use target designations from the wideband PLLs in guiding status and a prediction of frequency change caused by satellite movement. The adaptive receiver also includes channels with open PLLs in a standby mode.
