Abstract:

Fast acquisition and tracking of GPS signals are necessary in various military and civilian sectors. These are essential for operations under high dynamics as well as degraded conditions such as jamming and obscuration. Direct P/Y code acquisition under degraded condition involves external aiding in terms of precise time, ephemeris or other relevant data in order to facilitate the search process and also for long integration needed with data wipe-off. We have designed an architecture which allows these diverse conditions to be accommodated. Using block processing implemented in modern DPSs and FPGAs cost-effective receiver with flexible architecture is designed. Block processing is inherently suitable for P(Y) code as well as for several other new codes, particularly under high dynamics. CRS has developed novel software based development tools that allow rapid design, test, validation and prototyping of GPS systems using a single platform. We used this toolset for the simulation and design of Network Assisted GPS Receiver with direct P(Y) acquisition capability. During Phase II, we propose to develop a fully functional hardware prototype receiver and demonstrate its capabilities using simulated and live signals. We have demonstrated the feasibility of such implementation using commercial COTS components and using our software radio technology. The approach will provide means for future upgrades for different navigational signals and will allow easy implementation of advanced techniques for specialized applications.
