Abstract
This project initially examines the theoretical basis by which low cost “automotive grade” (typically devices with L1 signal tracking only) GPS and GNSS devices can be made to perform with a very rapid start-up and acquisition times and still maintain a high level of sub meter kinematic accuracy when in the presence of various local correctional data such as RTCM. The resources of such a chip set prevent the application of many traditional GPS methods to solve this. This advancement is needed to overcome today’s delays of up to one minute or more to become fully operational. This theoretical information which is developed is then used, as well as the performance of available likely chips, to design and develop a suitable optimized navigation filter. This filter will be demonstrated using both previously collected data sets, and live GPS designs which are implemented with today’s existing automotive grade OEM GNSS chip sets. Both L1-only and L1-L2 designs will be evaluated and constructed. Combinations of both GPS and GLONASS signals will be evaluated and used as well as existing standard corrections data sources. The resulting prototypes will be demonstrated over DSRC, 802.11, and also a low-medium frequency broadcast modem. Quantitative time and performance data will be collected.
