I set up the UAV in my backyard today so you can get an idea of the overall progress.


Just knocked up a labVIEW driver for the 3DM-GX3-45 GPS aided AHRS and what I can I say... AWESOME.

Microstrain have provided discounted pricing on a 3DM-GX-45 GPS aided inertial navigation system for use in the 2011/12 Outback UAV challenge. 

Key features of the 3DM-GX3-45:

  • Fuses data from GPS and AHRS to provide single optimal navigation solution.
  • RS232 or USB interface (I went for RS232).
  • Can compensate very well for GPS outages of 30 seconds.
  • Tiny size (24mm x 44mm)
