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.
