Attached are Params, Log, and Extrinsics file as requested. 

We are having an issue getting Local Position Estimate though all seems to be workign properly.    We also want to run OV instead of VIO but had issues gettign that running properly.  

The goal is to have as stable of a position hold as possible with YAw being the previous low quality issue at times.  We were suggested to run 1.6.0 as it fixes this with OV but again we had issues getting running that way. 

This build runs a seperate Autopilot running PX4 1.15.4 and we had it flying with previous Voxl 1.5.x prior to this.

I have Voxl_Logger running for 2 tests the first Log0000 is on the bench and then Log0001 is a quick log while in flight.
