[OKGIS] NMEA Output from GeoExplorer

[Wilard Gustafson]

Hi David,
I like to use DNRgarmin. It's free and provides real-time tracking 
with Garmin GPS units. It is supposed to work with other GPS units 
in NMEA mode so it should work with the Trimbles, however will not 
support the real time application in Arcmap.

Hope this helps,
Will
