  1. Ok, looking through the Datasheet by myself, maybe I found it at page 16: https://github.com/Tinkerforge/gps-bricklet/raw/master/datasheets/FGPMMOPA6H.pdf But I do not know how to relate this fixed CEP specification (which seems the best case) with the variable EPE measurement coming from the GPS Bricklet (often I receive about 1.3m, which is surprisingly low)... can I consider them equivalent measures?
  2. Dear TinkerForge, We recently bought a GPS Bricklet unit and we would like to have some more details about the data received in the callbacks. We successfully used the coordinate callback as explained here: https://www.tinkerforge.com/en/doc/Software/Bricklets/GPS_Bricklet_C.html#c-c-gps-bricklet The data contains also the EPE value which we read about here: https://www.nps.gov/gis/gps/WhatisEPE.html What we did not understand is which confidence interval is used: 50%, 68%, 95%, 99.7? We need this information to calculate the position covariance (standard deviation) following this approach: https://en.wikipedia.org/wiki/Standard_deviation#Rules_for_normally_distributed_data Many thanks, Guido
