Abstract
Honeywell has assembled a PC-based data acquisition system to collect digitized RF data from a GPS receiver front end, along with a test bed software set that uses the collected RF data to execute frequency domain acquisition, time domain tracking, pseudorange computation, and computation of GPS position solution. The test bed software is written almost entirely in Matlab with a few C-code files included to build Matlab executable (MEX) modules. This paper will describe the frequency domain processing techniques and also the rest of the post-processing that is executed.
