An advanced GPS geodetic survey receiver

Summary form only given. A novel commercial geodetic survey receiver which uses advanced tracking and postprocessing techniques to produce a high-performance, high-quality, robust survey tool has been developed. The receiver makes use of the P code modulation, and its operation in the event of P code being encrypted into the secret Y code must be considered. The tracking mechanisms and measurements and postprocessing techniques with Y code on or off have been examined, and results demonstrating receiver performance in the surveying environment have been obtained
