NOTE – The functionality to input or output any of these corrections depends on the installed options.

    Different manufacturers may have established different packet structures for their correction messages. Thus, Trimble OEM GNSS receivers may not receive corrections from other manufacturers' receivers, and other manufacturers' receivers may not be able to receive corrections from Trimble OEM GNSS receivers.

  • Navigation outputs:

    • ASCII: NMEA-0183 GSV, AVR, RMC, HDT, VGK, VHD, ROT, GGK, GGA, GSA, ZDA, VTG, GST, PJT,PJK, BPQ, GLL, GRS, GBS and Binary: Trimble GSOF, NMEA2000.

NOTE – Galileo support is developed under a license of the European Union and the European Space Agency.

NOTE – There is no public GLONASS L3 CDMA ICD. The current capability in the receivers is based on publicly available information. As such, Trimble cannot guarantee that these receivers will be fully compatible
