Once power is applied to the SXBlue GPS, the power LED will illuminate solidly and the
GPS LED will blink a few times, followed by a lamp test. Once the GPS lock LED has
finished blinking a few times, you will see the GPS lock, Differential lock, and the DGPS
position LEDs illuminate in sequence a few times and then go out.
When the SXBlue GPS acquires a GPS lock, the green GPS lock LED will illuminate solidly.
Similarly, the differential LED will illuminate when the SBAS demodulator has acquired lock,
or externally input corrections are being successfully received. The orange DGPS position
LED will illuminate when the receiver has acquired a GPS lock, differential lock, and has
applied corrections within the position solution. The above table provides more detail on
LED status.
The following image displays the front panel layout of the SXBlue GPS receiver, including
the location and labeling of each LED. For more information on LED operation and
troubleshooting, refer to Chapter 7.
