Abstract:

Real Instituto y Observatorio de la Armada ROA carries out daily intercomparisons of time and frequency using the GPS satellite system. For this type of links and for high-precision global comparisons, the use of geodesic GPS receivers is highly recommended, because it provides the solution using code P1P2 P3 and also carrier phase PPP. ROA has been operating two different class of these receivers PolaRx2 developed by Septentrio, Belgium since 2005 and GTR50 developed by DICOM, Czech Republic since 2006. Although the last one was initially developed for time and frequency comparisons using the GPS Common View CA method, this receiver can perform code and phase measurements and, after the issue of the last software version, it has provided the possibility of solution in carrier phase. In this paper, we present the comparison results of three GTR50 receivers, in two different setups common clock and zero baseline. Also, comparison with PolaRx2 data are shown and analyzed.
