4. Troubleshooting
4.1. Discontinuous Tracks
Intermittent power supply
issues are often the cause of this and are easily recognisable by:
• Multiple short tracks which constitute what should have been a single track between
point A and B
• An excessive number of 0 minute 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 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 both the Satellite and GPS LED on the Spider will turn off. On the
keypad, the Signal LED 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 from real-time. If the delay exceeds 120 seconds, the Satellite LED on
the Spider 8 will turn off, but the GPS LED will stay on to indicate that the unit still has a GPS
lock. The Signal LED on the keypad will turn orange.
The Spider uses temporary memory to 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.
