Description:
  The GNSS receiver type. The currently identified types reflect
  the protocol(s) supported by the receiver:

   ======  ===========
   "NMEA"  NMEA 0183
   "SiRF"  SiRF Binary
   "UBX"  UBX
   ======  ===========

  Note that also non-"NMEA" type receivers typically support a
  subset of NMEA 0183 with vendor extensions (e.g. to allow
  switching to a vendor protocol).
