Multi-Aircraft Inertial Navigation Data Fusion Method Aided by One Pseudolite

Pseudolite aided all parameters weighted least squares (PAAPWLS) data fusion method is proposed to improve multi-aircraft inertial positioning accuracy. The data fusion system was mainly composed of the inter-flight data link, inertial navigation system (INS) and one pseudolite. The data link performed two functions: real-time communication and mutual ranging between aircrafts. INS provided position data. The pseudolite receiver outputted distances between aircrafts and the pseudolite. The PAAPWLS algorithm was applied to data fusion in order to estimate the multi-aircraft inertial position errors when the aircrafts fly across the pseudolite. Simulation results show that the method works effectively and the position error can be improved to less than 40m (1σ) with the help of the method.
