Lady Heather can output RINEX (v2.xx and 3.xx files) for most receivers that output pseudorange and/or carrier phase data. I have tested it with the Ublox 4T, 5T, 6T, 8T, F9P, and F9T receivers. Also the Venus RTK receivers, Trimble NetRS, Ashtech Z12,, NVS08, Trimble timing receivers, and a few others.
With my horrible antenna location L1/L2 devices yield positions error ellipses around 10 mm. lat/lon and 50mm altitude L1 only devices are around 100 mm. People with better antenna locations have reported error ellipses is the low mm range. The Trimble receivers are currently a bit wonky since I have some issues calculating pseudoranges from the Trimble data. I didn't have Trimble issues before CSRS-PPP "upgraded" their processing software. The version of Heather that I am currently working on can apply sawtooth corrections to the PPS output measured by a counter such as the TAPR-TICC in order to make a better "paper clock". ------------------ > As Bob says, the ublox chipsets from generation 6 onwards are probably the best value as they can be configured to output the raw measurements for precise position/time. _______________________________________________ time-nuts mailing list -- time-nuts@lists.febo.com To unsubscribe, go to http://lists.febo.com/mailman/listinfo/time-nuts_lists.febo.com and follow the instructions there.
