Abstract
CRS has developed software based simulation and development tools, for advanced GPS systems. These tools (in conjunction with associated hardware) allow rapid design, test, validation and prototyping using a single platform. We propose to use this toolset(and associated hardware) for the simulation and design of Network Assisted GPS Receiver with direct P(Y) acquisition capability. The software tools will also be used to generate degraded signal conditions (jamming, weak signals, multipath), which can beused with hardware Digital Storage Unit to replay the signal at GPS frequencies.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. The toolsetavailable with CRS will allow simulation of variety of conditions as well as rapid prototyping and live demonstration.During Phase I, we provide a simulation and initial test results along with plans for hardware receiver implementation for Phase II. The proposed technology will have both Government and commercial applications. Precision GPS operation under weak signal conditions will be needed by a variety of Govt. agencies. Application range from detection of GPS inside building, undergroundinside tunnels, valleys, submarines, in space (for satellite based navigation at large distances), etc. These are unlimited civilian applications involving underground positioning in caves, mines, urban areas, and so on.
