Abstract:	This paper shares the implementation details of a real-time vector tracking receiver as constructed on a system-on-chip platform. Vector tracking receivers boast many benefits including the ability to track satellites at low carrier-to-noise (C/N?) ratios and instant reacquisition of satellites after brief outages. While vector tracking receivers offer many benefits, those benefits come at a high computational cost. For that reason, the authors have sought to construct a small, low-cost solution for a vector tracking receiver. The receiver described here takes advantage of the high-speed parallel processing capabilities of an FPGA while incorporating a dual-core ARM processor. This structure helps to overcome many of the difficulties of implementing the vector tracking algorithms in real-time.
