Abstract
A method of processing signals from a satellite positioning system, comprises receiving () recorded blocks of data samples of satellite broadcast, each block including one or more timestamps generated within a receiver at which the samples were recorded, and processing () the recorded blocks of data samples using a first set of processing parameters to identify satellite transmissions contained within the blocks. Based on the results of the processing (), one of the blocks is selected (). The selected block is processed () using a second set of processing parameters to derive at least position and satellite broadcast timing information. The timestamp of the selected block and the timing information obtained from the processing () of the selected block is used to assist in the processing () of the other blocks. The method associates timestamps with satellite data to improve the offline processing of the positioning data (for example by providing accurate relative timing information between data samples), and this can reduce the processing power and/or time to process the data.
