Accurate gps for vehicle-to-vehicle communication safety application

The project integrates and optimizes an accurate gps for the usage of vehicle safety application. Vehicle-to-vehicle communication relies on accurate positioning and cheap cost. Both of those targets are addressed by this project.

Vehicle-to-vehicle communication aims to dramatically reduce the number and severity of traffic accidents. Having a reliable positioning is a pre-condition for reliable safety alerts. The value of vehicle-to-vehicle communication for safety depends on mass market penetration, and that will be achieved only when cost is low. The project integrates high-end GPS functionality inside a vehicle-to-vehicle communication chip. By that, several advantages exist: 1. High-end GPS: Automotive grade solution with better performance than currently available 2. Availability of fresh GPS location: GPS location doesn't need to pass through various interfaces in the vehicle. 3. Reduction of total system cost. The end result will provide the most accurate position to the safety application. Drivers will enjoy high reliability safety alerts at a lower cost. The way those advantages are obtained are: 1. High-end GPS: A. GPS is designed to support concurrent operation of GPS and Glonass for doubling number of viewed satellites. B. The processing is based on SW, enabling future upgrades, for example to Galileo, and adjustments in the fields. C. The platform is optimized for high processing. High update rate can be supported. Today, Automotive GPS supports 1Hz update rate (one location update per second), while state-of-the-art devices supports 10Hz update rate. D. Integration of vehicle data to GPS dead-reckoning algorithm, for maximal accuracy at urban canyons and tunnels. 2. Fresh GPS location: An external GPS is typically connected via UART, typically at 115Kbuad. A message would be delayed by several milliseconds. Furthermore, vehicle CAN buses may be used to carry the information, and in that case, latency will further increase since these buses are typically slow and congested. The new solution is located on-chip and has minimal latency. 3. Reducing total system cost: Since GPS is integrated in a multi-function device, the cost increase over a stand-alone device is reduced. The differential cost of silicon, testing and required memory is far lower than a cost of dedicated elements.
