GPSpvt
Reading Position, Velocity, Time from a GARMIN GPS via native USB
A program to read PVT (Position, Velocity, Time) from a GARMIN GPS via the USB port in its *native* USB mode.
Detailed device info, as received from the GPS, and PVT will be printed to screen and saved to file 'gpspvt.log'.
Tested on device 'GARMIN GPSmap 76CSx' (marine-type, handheld GPS), which has the Garmin GPS Product_ID: 292, and Garmin GPS SoftwareVersion: 3.90, and has lsusb info: 'ID 091e:0003 Garmin International GPS (various models)'.
GPSpvt will probably run on most Garmin...
