Abstract:
1. A Global Positioning System (GPS) receiver comprising: a first section having a signal acquisition stage for acquiring an input signal and a sampling stage for sampling the input signal at a sampling data rate to provide sampled data; and a second section having an I/O data buffer for receiving and buffering the sampled data and providing the buffered data to tracker hardware, wherein the tracker hardware operates at an operational rate which is greater than the sampling data rate of the input signal enabling multiple cycling of the buffered data by the I/O data buffer, wherein the tracker hardware is single channel receiver hardware behaving as multi-channel receiver hardware wherein the tracker hardware includes a plurality of Field Programmable Gate Arrays for operating the tracker hardware at the operational rate, further comprising a first processor for at least performing navigation functions and controlling the tracker hardware, and a second processor for at least performing tracking functions, wherein the first and second processors are interfaced by interface hardware.
