一种基于误差包络的多径抑制性能评估准则
Evaluation of Multipath Mitigation Performances Based on Error Envelope
摘要
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 pefformance. 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 above two techniques and narrow eorrelator technique were presented. This research can be used as a guideline for the parameter design of mulfipath mitigation techiques in GNSS receiver.关键词
