Hi OSM GB, I've recently been experimenting with Real-time Kinematic (RTK) "GPS" GNSS receivers and RTKLIB with some reasonable success. I've been able to get repeatable centimetre level position accuracy. I've been using u-blox NEO-M8T chipsets.
Unfortunately there are very few open and realtime RTK/RTCM NTRIP streams available in the UK. The lack of access to a reasonably nearby stream limits the RTK to mostly post-processing application. The open live streams I have found for the UK are at Daresbury, Inverness, Shoeburyness. All of which are in excess of 70km from where I live. OS Net has good coverage, but is commercial. They do provide open access RINEX post processing data, 24 hours after capture: https://www.ordnancesurvey.co.uk/gps/os-net-rinex-data/ I'd be interested to know if anyone else has been experimenting with RTK? Do you need a live RTCM stream for experimenting / survey? I can create one, happy to travel closer on the weekends too. I use a Emlid Reach RS. Kind regards, Grant _______________________________________________ Talk-GB mailing list Talk-GB@openstreetmap.org https://lists.openstreetmap.org/listinfo/talk-gb
