In the actual GNSS space signal quality monitoring system, the performance of the channel is not ideal, resulting in the signal transmitted to the receiver is inconsistent with the signal received by the antenna. Studying the characteristics and designing the equalization algorithm of the channel could restore the received signal to the real state, which will ensure the quality monitoring results...
Multipath delay is one of major error sources which limit global navigation satellite system (GNSS) positioning accuracy. Duo to the orbit characteristics, multipath effects on the code observables of geostationary earth orbit (GEO) satellites are more evident and can be tracked continuously over long time scales. We introduce a data processing technique, based on residual analysis, zero-phase filter...
