2.2 LED Fix Indicator
Image 4: LED Indicator
On the left-side of the TN-202 is a small LED, which indicates when the device is initializing a GPS fix
and when enough satellites have been received to produce a GPS fix either in 2D or 3D. From your
GPS software you should be able to see the signal status of whether you are receiving either 2-D
(Latitude and Longitude) or a 3D (Latitude, Longitude and Altitude) fix. If you are not getting the desired
results for GPS signal strength, or adequate satellite coverage using the built-in GPS antenna, you may
want to consider using the included external GPS antenna.
