Noise and the 3DR uBlox LEA-6 GPS

3DR uBlox LEA-6 GPS + secret sauce

I'm evaluating a 3DR uBlox LEA-6 GPS for use on Data Bus to either replace or supplement its current module, the Venus 638FLPX.

At first the GPS could not obtain a fix. Here's how I brought the GPS from no fix to a 10-satellite fix. From my basement!

Ramp Jump Breaks Data Bus

I built a ramp very similar to the one for the 2013 AVC so I could get a sense of how the robot will handle the jumps.

Unfortunately I stripped out one of the plastic idler gears doing a high speed jump. I've got a metal set on order to arrive Friday.

Can you see the stripped teeth on the small idler gear?

I was hoping to test my revised path following algorithm. That'll have to wait until I replace the gear set. More on the path following algorithm soon.

Just under four weeks left.
