In the urban environment, multipathgreatly deteriorates GNSS(Global Navigation Satellite Systems) positioning performance. In such environment, the first arrival signal detection technology is necessaryto realizean accurate navigation system. Super-Resolution technology is a method for mitigating the effects of multipath. MEDLL(Multipath Estimating Delay Lock Loop), SAGE(The space-alternating generalized expectation–maximization) and LIMS (Least-Squares based Iterative Multipath Super-Resolution) are representative of Super-Resolution algorithm. In this paper, we evaluate performance of Super-Resolution technique by demonstratingdetection accuracyand computation of the algorithms.
