GPS Fix, Is My Spider Connected to the Network?


You can check to see if the GPS is getting a fix (it should get a fix, if outside within about 45 seconds of being switched on) by powering the unit and waiting for the appropriate indicator (see table below). 


Version of Spider Power indicator GPS indicator Iridium indicator LED location
Spider 1 (aluminium and plastic)  LED turns Red LED turns Green N/A Beside power connector
Spider 2 (plastic, blue cap) LED turns Red LED turns Amber N/A On top of unit/Spider Abdomen 
Spider 3
Spider 4
Spider 5
Left Power LED comes on       Right Sat LED turns Amber       Right Sat LED turns Green      On front of unit/keypad


In Figure 1, the Spider is still acquiring a GPS fix, you can tell this by the amber light on the on the GPS indicator icon.   


In Figure 2, the Spider as acquired the GPS it needs to transmit and the green LED means the Spider has established connection with Iridium. This light should remain solid.

Please also note, that GPS will get a fix relatively quickly when stationary, but if the aircraft is already moving, there is a reduced chance that the GPS will get a fix.

Standard procedure is to wait until the GPS has a fix before starting to fly. If you turn the Spider on as soon as you get into the aircraft, it will get a fix whilst preflight checks are carried out, and (if on Automated Watch) will not send out unnecessary points until you start to fly.

What is your Spider does not get the GPS or Iridium fix?

Testing the Spider outside the cockpit can help eliminate whether the Spider is being affected by something or in a poor position.

If your spider displays a Solid Blue Watch LED (see image below), please view Bootloader Mode, in Updating Your Firmware.
