I currently use a Topcon GRS-1 which is Dual-frequency but, as it is older, only supports GPS and Glonass.
Would a newer Single-frequency receiver that supports GPS, Glonass, Beidou, Galilleo and SBAS give me better results in the UK?
eg: better chance of fixed solutions under tree canopy or close to buildings.
Do any of you have experience of such a receiver? (eg: Trimble R1)
A newer Dual-frequency model is beyond my finances at present.
