Investigation on Reference Frames and Time Systems in Multi-GNSS [PDF]
Remote Sensing, 2018 Receivers able to track satellites belonging to different GNSSs (Global Navigation Satellite Systems) are available on the market. To compute coordinates and velocities it is necessary to identify all the elements that contribute to interoperability of the different GNSSs. For example the timescales kept by different GNSSs have to be aligned.

Multipath Error Fusion Modeling Methods for Multi-GNSS [PDF]
Remote Sensing, 2021 The multipath error is considered to be the most limiting factor for high precision positioning applications. The sidereal filtering (SF) method can be used to mitigate the multipath error in the observation domain, and it has been successfully applied in the multipath mitigation in global positioning systems (GPS) and regional BeiDou navigation ...
