Title :
Collaboration-Enhanced Receiver Integrity Monitoring (CERIM)
Abstract :
This paper introduces a method of monitoring for navigation satellite faults by pooling measurements for a team of vehicles connected through a wireless Vehicle-to-Vehicle (V2V) network. The new method is called Collaboration-Enhanced Receiver Integrity Monitoring (CERIM). Compared to existing satellite-navigation integrity technologies, such as Receiver Autonomous Integrity Monitoring (RAIM), Space-Based Augmentation Systems (SBAS), or Ground-Based Augmentation Systems (GBAS), CERIM has particular advantages for intelligent transportation systems, because of its potential for high sensitivity and fast response time, and because of its ability to operate without an infrastructure of stationary reference receivers. A method for computing the missed-detection probability of CERIM in the face of single-satellite faults is derived and evaluated using simulation.
