NLOS Satellites Detection Method Applying Relative Positioning

In this paper, we present a detection method for non-line-of-sight (NLOS) satellites applying relative positioning. NLOS satellites affect the accuracy of positioning, and conventional approach to reduce the effect of multipath cannot improve the low accuracy. So, we propose the method to apply relative positioning. This method does not need some special devices or complex computations. In this paper, the observe at the fixed point and open sky condition is carried out to simplify the verification. The NLOS satellite was simulated by modifying the information obtained from the line-of-sight (LOS) satellite, and this method was applied. As a result, the NLOS satellite was successfully detected in approximately 98% of the simulation time.
