Acquisition method with improved frequency multi-correlation

摘要

The method involves summing successive results of frequency-augmented correlators (14) at instants during an integration period of results of multi-frequency correlation. The summated results of one of the correlators are transferred to the summated results of the other correlator if an error induced at an output from the correlator expressed as an integer number of code spaces between code correlators (12) at each of the instants has increased relative to an induced error expressed as an integer number of code spaces between the code correlators at the output valid in previous instant. An independent claim is also included for a receiver of satellite positioning system.
