Abstract:	This paper introduces NAV2300, a 12 channel and single frequency C/A code GPS receiver. Latest addition to the NAV2KÔ family of solutions, the receiver core is realized around a single programmable fixed-point Digital Signal Processor (DSP) microcomputer from Analog Devices. The receiver is based on a unique Soft-CorrelatorÔ architecture, which allows the complete GPS signal processing as well as navigation processing functions to be implemented on a single programmable fixed point DSP. This flexible implementation lends itself naturally for interfacing with any standard RF front end. It has all the advantages associated with a software solution, such as scalability, upgradeability etc. The low cost, high performance DSP microcomputer totally eliminates the necessity of a microcontroller, usually required by conventional receiver architectures. The solution includes a Programmatic Interface to the NAV2300 Core, which facilitates the OEMs to embed their own applications on the NAV2300 core along with the GPS function.
