The saturation sensors during the flight. How to overcome?

[A.Kirillin]

Hi Tom! Hi ALL!

With aggressive flight in manual mode there is an overload sensors. Artifical horizon GCS ceases to show the position of the aircraft. Correctly displays only the data GPS. When you switch mode Autopilot - a downward spiral with a strong roll.
I am down to earth model and power off for a while. Is it possible to in-flight "reset" the sensors?

PS: After the winter has made the first flights. Gluonpilot works perfectly. Turn and fly!

Andrey.

Hi Andrey,

Glad to read you are still "airborne"

Yes I know some weird maneuvers can freeze the IMU. I don't know if saturation has anything to do with it. During a "normal" flight this never happens. I will need to put some time in debugging

Tom, last week i have managed to freeze the IMU two times.
I think I have some data on that - would need to download the log file from gluonpilot.
Also I have on board video that shows the maneuver an the moment the IMU freezes.

Generally in my case this is easy to reproduce. Do an aggressive turn at more than 90degrees.

I solved the issue!

Hooray

Will be available in the next beta

[lukasz]

Gr8!
How much Betas are you planing

[Tom]

Please check beta 4 if you haven't checked the SVN yet

Thank you for your work, Tom! I soon check it!

Did you enter the clouds on autopilot?

Did you enter the clouds on autopilot?

No. It is terrible now . Need to be prepared properly. I fly infrequently and spontaneously. I used the manual and stabilized mode. Flying in the clouds a little time and without visual contact. Back with the autopilot. I did not have the Internet, and therefore maps of the place.
But I'll try to make an autonomous ascent and descent this week ... I hope that I will have enough time.
It is difficult to write a program flight. We must consider all the possible reasons of automatic termination of the program and return to earth. It also may have to use a separate battery to power the entire control electronics. To improve the reliability of the return to earth.
On land the plane back anyway, but would like to somehow mark the place of return.

I usually do cloud flights using relative circles:

5. BLOCK(CLIMB)
6. CIRCLE_REL(0m, 0m, radius: 120m, altitude: 1000m)
7. GOTO(6)
or
7. WHILE (CHANNEL6 < 1500)
8. CIRCLE(0m, 0m, 120m, 100m)
9. GOTO(8)

You can also use the battery-alarm command to make sure the plane will descent when the battery is empty!
