2.0.50 is a work in progress, but this video highlights the Altitude hold progress in the latest code. 

   

 

 

Changes include a faster Baro filter to reduce latency and temperature induced noise. Alt hold control using the throttle has been upgraded to have a faster and proportional response. 

 

Acro mode has been enhanced and now has it's own duplicate set of Rate PI's for more flexibility.

I'll have this posted in the next two days to GIT and the mission planner.

Be careful--you'll kill the sales of our sonar sensors! Seriously, congrats--that's impressive indeed. Just imagine what that might do with a better baro sensor in the next version of APM, if such a thing were to exist ;-)

Jason, that seems to be a big improvenment. Looks really great! 

Maybe you have implemented a secret 'warp drive' function ? I saw somethink like that at 0::55  :)

@thomas

wow - the warp function is the further development from the function olivier adler mentioned: rocket climbing.

0.55 min. It can invisible function ? ^U^

Jason, what do you mean by faster baro filter?  Just running the control loop faster or are you doing some sort of estimation filter?

Comment by Juan Carlos Hdez on November 1, 2011 at 7:03am

Wow. impressive

I hope you can still change altitude more smoothly too, like it is today ?

now i want to load the the git version. One of my quad has no sonar (removed intentionally) since v42. v50 looks promising. If only the rain will stop in the morning and in the afternoon which is when i do my testing.

OK, I just posted the new code on GIT this morning.

Good luck,

The fact that you are no longer flying in the park and that you can do it in that very space limited backyard is really showing how "accurate" the flight is becoming. 

good work Jason! will most likely test flight it before the end of week. 

By any chances, did you put back the motor mount light code in the 1280 board version? 

getting quite dark around here and it was nice to get these all working without having to change the code.
