SDR GNSS Receiver Design over Stand-Alone Generic TI DSP Platform

Abstract

Recent research on SDR (software defined radio) GNSS receiver is mostly based on DSP/FPGA hybrid or PC platform. In this paper we will introduce a prototype design of SDR GNSS in stand-alone DSP platform. The GNSS receiver with has more than 12 GPS channels, which is implemented in a TI TMS320C6416 DSP chip. The chip will fulfill acquisition, tracking and positioning function in realtime. This method could be extended to other navigation constellation to archive multi- onstellation GNSS receiver.
