Abstract

Multipath reflections degrade considerably the precision of positioning and timing services introduced by the Global Navigation Satellite Systems (GNSS). Various techniques were introduced to mitigate the effect of multipath errors. One of the most commonly used techniques is weighting the received data according to the elevation angle of the observed satellite. Another technique was proposed by the author in which the optimum elevation mask (OEM) concept was introduced. In this paper, the author compares the efficiency of both the weighting and the OEM techniques. Moreover, the author proposes a mix between the two techniques to be more efficient than using either of the two techniques separately.
