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)
