Abstract

An absolute calibration method of RDSS (radio determination satellite service) channel is proposed. The RDSS signal is used as the test signal. The input and output for RDSS channel are sampled in synchronization. The sampling data is truncated and Hilbert transformed. The carrier rotation is done for the input or output data of the RDSS channel. The input data of RDSS channel is correlated with output data. After the peak of correlation is searching, the absolute delay of RDSS channel can be obtained. The propose algorithm need not make acquisition and tracking for spread spectrum signal. The calibration uncertainty is mainly dominated by the sampling frequency.
