GPS has been joined by other GNSS constellations, including the Russia’s GLONASS, the Chinese BeiDou and the European Galileo constellations. Although GPS has become widely used by businesses Estimation of Inter-System Biases between BDS-3/GPS/Galileo and Its Application in RTK Positioning. B2b, and B3I, it performs better than B1I, whose RMS of MP va ries from about 0.45 m (at The results collated in Table 2 evidence a better than 0.1 ns, or 3 cm, agreement of HAS and CAS values for the GPS C1C-C2L, while the Galileo DCBs exhibit slightly larger RMS errors of 0.1–0.2 ns. Table 2 RMS errors for GPS and Galileo DCBs from HAS pseudorange biases relative the CAS reference values The combined BDS3/2 solution is slightly better than GPS-only and Galileo-only solution. The fusion of GPS + GLONASS + Galileo + BDS3/2 can achieve the highest accuracy, with a 3D STD value of 0.63 cm, which is reduced by 46%, 52% and 35% when compared with 3D STD values of GPS, Galileo and BDS3/2, respectively. I’ve never had battery issues using GPS+GLONASS. Since 11.0 ive been using GPS +GALILEO. No battery issues. I don’t know which is best - I assumed that GPS+GALILEO was better than the other options. Hopefully someone will enlighten us. Nick While the US maintains its primary concerns over Galileo are linked to national security, others say they do not want the European system to be better than GPS. 0BPbK. The average convergence time of Galileo-only kinematic PPP in 2018a is 87.3 min, which is twice lower than that of GPS-only. By combining the Galileo and GPS observations, the positioning accuracy is significantly increased compared with that of Galileo-only, while it is comparable with that of GPS-only. GPS Time and Navigation. Each GPS satellite carries Atomic clocks that are precisely synchronized to a common time scale “GPS Time”. GPS Time is kept in closet alignment with UTC(USNO), typically within 10 nanoseconds. Each GPS satellite also broadcasts its precise position in space (typically better than one meter) The obtained results confirm that the Galileo solution has comparable accuracy to the GPS solution. Also, with the Galileo solution, the best results were obtained for functions with a smaller dependence on the elevation angle than for GPS, since Galileo observations at lower elevation angles have better performance than GPS observations. This process means UTC time measurements can also be made available to users to within an designed accuracy of 26 nanoseconds, although in practice Galileo has been able to do better than this – down to about 5–10 nanoseconds. Finally, GST also needs to be kept in synch with time system underpinning the US GPS system, known as GPS Time. Garmin GPS receivers. Garmin GPSMAP. GPSMAP 66. GPSMAP 66s/st  Translation  GLONASS and GALILEO usage. Discussion related to the Garmin GPSMAP 66s/st GPSr The positioning services are more accurate at higher latitudes with Galileo than with any other positioning services. Current estimates have Galileo offering limited service by 2015 assuming the EU managed to work out frequency issues with the Beidou. Once operational, Galileo will be available to users worldwide, though the EU will pay for it.
