User:Deanna Earley/SiRF Star III
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)
with sirfmon (part of the gpsd package) you can activate WAAS mode using the binary sequence:
s 85 01
- send command
- DGPS Source
SiRF Binary and NMEA docs are available here:
