2013The densification of GPS networks in the national reference system is usually performed at the final stage of computations using a similarity transformation on the projective plain, resulting from the best fit of the new coordinates of common stations of Greek Geodetic Network- new GPS network, to the known values. This procedure leads to dependency or

GNSS Bias Calibration System: GNSS-BICS system prototype
2012 6th ESA Workshop on Satellite Navigation Technologies (Navitec 2012) & European Workshop on GNSS Signals and Signal Processing, 2012Nowadays the estimation of the differential group delays amongst different navigation signals is performed at the different GNSS Control Centres by processing GNSS multi-frequency observables gathered by ground sensor stations. A significant improvement can be envisaged if the estimation is aided by multi-frequency observables from GNSS receivers ...
