Delay Calibration Algorithm for BOC Channel of RNSS Using Partial Correlation
The delay caused by navigation signal transmission equipment of RNSS (Radio Navigation Satellite System) is a part of the whole link delay and must be subtracted in the application of positioning and timing.The absolute calibration of the transmission channel is affected the positioning and time transfer accuracy.The proposed delay measurement technique of BOC (Binary Offset Carrier) navigation signal transmission channel is based on digital signal processing.The BOC signal of navigation satellite and the 1PPS (1 Pulse Per Second) generated by navigation time keeping system are sampled in synchronization.The BOC signal data is processed using carrier-phase acquisition.The integral time is less than a period of the PRN (Pseudo- Random Noise) sequence.The start point of the PRN sequence is obtained and the absolute delay of BOC channel is calculated.The absolute uncertainty with the proposed algorithm is less than 0.2ns when the sampling frequency is 10 GSa/s.
