+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).
