| Abstract: | Multipath error is one of the last obstacles for GNSS performance improvement,and accordingly multipath mitigation techniques are developed rapidly.However,there is a lack of evaluation rules for the multipath mitigation performance.Three evaluation criteria based on the multipath error envelope were proposed;the multipath error formulae for both ELS technique and Double-delta technique were derived for the first time;hence calculation expressions of the multipath mitigation performance evaluation for the a... |
