Abstract
GNSS is the most accurate mean of navigation but it relies on satellite being available, and these signals are susceptible to interference due to their low received signal power. To deal with possible unintentional/intentional signal loss or degradation vulnerabilities and spoofing threads, and to maintain system accuracy and integrity an alternative backup DME/DME based navigation system is proposed. The article describes the implementation and performance of purposed DME/ DME based system solution together with simulated and real test data/results. Shared recorded data from the flight tests compared with GNSS signals verify the effectiveness of the proposed mitigation algorithm. We first give details of proposed DME/DME joint mitigation algorithm. We then present the simulated results and show backup navigation capability with accuracies better than 0.1 nautical miles. Finally, we share real flights campaign measurements performed at TAI/TUSAS facilities in Ankara, Turkey to show performance of algorithm.
