Yo All! Anyone wathcing git head, or issue 175, will notice that I have been workong on NTRIP. Still a lot of rough edges, but progrees. See attached one one plots, all from the same ZED-F9P and antenna. Plain3600.png -- no corrections 23Single3600.png -- RTCM 2.3 corrections (1 mile away) 3Single3600.png -- RTCM 3 corrections (1 mile away) MAX3600.png -- "MAX" synthetic RTCM 3 correction. All from the Oregon ORGN network. Many thanks to them for allowing me cess. The CEP(50)s: 0.764m Plain3600.png 1.149m 23Single3600.png 0.719m 3Single3600.png 0,044m MAX3600.png Things to note. a) RTCM 2.3 made the CEP(50) worse! b) RTCM 3 was barely better than no corrections c) The synthetic corrections are just WOW. u-blox just announced a commercial sat based correcton service that will beam corrections to any paying customer. TBD if their corrections are useful, or if normal people can afford them. RGDS GARY --------------------------------------------------------------------------- Gary E.
