A method for authentication of the GPS transmitter

The activities related to IRNSS (Indian Regional Navigational Satellite System) are at the peak at this time. It includes the integration of GPS, GNSS (Global Navigational Satellite System) and Galileo navigational systems. The single chip solution looks at integrating the RF/IF block with the digital signal processing block on a single chip. Such solutions invoke the possibilities of integrating GPS with the technologies like GPRS, GSM, etc. The goal of the experiment is to implement and authenticate the GPS system on the Texas Instrument DSK TMS320C6713. As a part of that in this paper an approach to implement and authenticate the GPS transmitter on the DSK is described. MATLAB is used to implement each blocks of GPS transmitter. First part of the paper describes the software implementation of the GPS transmitter, and the later part contains the description of the hardware implementation and the authentication of the same.
