Garnix for Linux, Windows, or DOS

The installation of Garnix is basically the same for Linux or Windows/DOS.

Download the appropriate binary file and uncompress it into a new direc-

tory. For the Linux version, you need to make the program executable with

chmod +x garnix. Source code is also available, as well as an interesting doc-

ument that reverse-engineers the Garmin protocol.

To check that it is working, make sure you have the GPS set in Garmin pro-

tocol mode and connect the GPS to your serial port. Under Linux, you may

need to be root, or run sudo, to have access to your serial port.

[rich@testingrange garnix]$ sudo ./garnix

If you can’t remember an option, type garnix -h for a terse help screen.

Garnix has three different display formats: degrees-minutes-seconds (DMS)

with symbols, DMS with abbreviations, or Waypoint Plus format.

Here’s how to apply the three formats to waypoints.

Waypoints in DMS with abbreviations (“text” mode):

$ garnix -w -x -f myway.txt

Example:

38deg 24min 12.32sec ...
