摘要： A method of receiving and processing an RF signal comprises receiving (5) the RF signal; analogue processing the signal and providing a digital output to a digital signal processor, the digital output including an added identification code unique to an RF front end receiver hardware. Within the digital signal processor, the identification code is compared with a predetermined identification code or set of codes to determine if there is match. If there is a (10) match, the digital output is processed to provide data to the user, and if there is not a match, an error function is implemented. This method enables a software developer to make the system function only when there is a match between the hardware and the software. This makes copying the software as difficult as copying the hardware, because (15) copied software will not work with the incorrect hardware batch.

摘要： A method of processing signals from a satellite positioning system, comprises receiving (50) 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 (52) 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 (52), one of the blocks is selected (56,58). The selected block is processed (60) 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 (60) of the selected block is used to assist in the processing (60) 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.
