Multi-Constellation Time-Differenced Carrier Phase Solution with Protection from Multiple Failures

Zhen Zhu, Eric Vinande, Maarten Uijt de Haag

Abstract:	A multi-frequency, multi-constellation GNSS receiver takes advantage of the number and variety in satellites and signals. However, integrity monitoring faces a new challenge, as the traditional fault detection and exclusion algorithms were not optimized for the multiconstellation users. We introduce a random sample consensus method to monitor the integrity of a multiconstellation velocity and displacement solution using time differenced carrier phase. The monitor is ideal for a large set of measurements, and is natively robust against multiple failures. The algorithm will be optimized for real-time implementation in an embedded system.
