5*4882a593SmuzhiyunDescription:
6*4882a593Smuzhiyun		The GNSS receiver type. The currently identified types reflect
7*4882a593Smuzhiyun		the protocol(s) supported by the receiver:
8*4882a593Smuzhiyun
9*4882a593Smuzhiyun			======		===========
10*4882a593Smuzhiyun			"NMEA"		NMEA 0183
11*4882a593Smuzhiyun			"SiRF"		SiRF Binary
12*4882a593Smuzhiyun			"UBX"		UBX
13*4882a593Smuzhiyun			======		===========
14*4882a593Smuzhiyun
15*4882a593Smuzhiyun		Note that also non-"NMEA" type receivers typically support a
16*4882a593Smuzhiyun		subset of NMEA 0183 with vendor extensions (e.g. to allow
17*4882a593Smuzhiyun		switching to a vendor protocol).
