A number of poeple have a SiRFStar III based GPS mouse but use Linux and so, are unable to run the included GPSInformation utility. With the use of Portmon from SysInternals, I have been able find out what commands you need to enable WAAS/EGNOS, etc..
These all follow the standard NMEA format witht he checksum and CR LF on the end of the sentance (after the asterisk)
WAAS/EGNOS
Enable:
$PSRF151,01*0F
Disable:
$PSRF151,00*0E
with sirfmon (part of the gpsd package) you can activate WAAS mode using the binary sequence:
s 85 01
- s
- send command
- 85
- DGPS Source
- 01
- SBAS
Power saving
Enable:
$PSRF150,0,300,1000,1*10
Disable:
$PSRF150,0,1000,1000,0*23
