4. Troubleshooting
4.1. Discontinuous Tracks
Intermittent power supply power issues are often the case of the and are easily
recognisable by:
• Several short tracks which constitute what should have been one track between point
A and B
• An excessive number of 0 min tracks
• Missing tracks (last track terminates at point C, next track originates at point D)
• Last point in track is at a high altitude and/or airspeed (in the absence of a point
delay issue)
• In the case where a Spider is operating in Watch mode, an undesirable outcome of
erratic power cycling may be a tier one alert being fired
Generic Causality
• Spider is powered by auxiliary power outlet (cigarette lighter) which is subject to
interruption from bumps, knocks, and vibration
• Spider is powered by a battery pack which is unable to deliver enough current, and/
or is running flat
4.2. Lost GPS
If the GPS signal is lost, the GPS LED on the Spider will turn off. It is not uncommon to drop
a GPS lock but occurrences should be infrequent and not last for periods of more than a few
seconds.
4.3. Lost Iridium Connectivity
If the Spider can not connect to an Iridium Satellite for a short period of time there will be a
transmission delay. If the delay exceeds 120 seconds, the GPS LED on the Spider 6 will turn
orange.
The Spider uses a queue and can store a maximum of 10 points, therefore even if the
Spider is struggling to send position points, it can still add points to the queue as long as
there is a GPS lock. Once the Satellite connection is re-established, the Satellite LED on the
Spider will turn back on and the Signal LED on the keypad will turn green.
