High Integrity Multipath Mitigation Techniques for Ground Reference Stations
High Integrity Multipath Mitigation Techniques Ground Reference Stations
2015/6/29
There is an increasing demand for accuracy, integrity,continuity and availability in the ongoing develop ment of differential GPS (DGPS) techniques. DGPS performance relies on the elimination of error...
Software-based Multipath Mitigation: Sampling for Multipath Invariance
Software-based Multipath Mitigation Sampling Multipath Invariance
2015/6/29
Multipath potentially introduces a significant bias error into GPS code phase positioning solutions. That error is dependent on the amplitude, delay, phase, and phase rate of the multipath with respec...
The Multipath Invariance Approach for Code Multipath Mitigation
Multipath Invariance Approach Code Multipath Mitigation
2015/6/29
The concept of multipath invariance asserts that there exist properties and/or regions of the code correlation function that do not change as a function of the multipath amplitude, delay, phase and ph...
Narrowband receivers are more robust to narrowband interference and to GPS signal faults, but they tend to have relatively poor multipath performance. Few current techniques are capable of mitigating ...
