A team of U.S. Air Force pilots tested a novel backup navigation system that utilized cellphone signals.
The system could track the plane for more than a hundred kilometers, and at various altitudes, with precision in the single-digit meters.
The results are described in a study published 20 June in IEEE Transactions on Intelligent Transportation Systems .
In one test flight, the radio SLAM system was able to track the plane with a statistically calculated error of just 7 meters .
The data wasn’t processed in real time during these test flights, but afterward.
In particular, new computational designs will need to be developed for real-time data analysis.
