Set Attitude Estimation Algorithm
To use all the navigation features using GPS,select the GPS navigation (INS13) attitude estimation algorithm
Go into Attitude page > Settings > Attitude Estimation Algorithm, select GPS Navigation INS13, and Save.
Set the flight mode
Go into Input page > Flight Mode Switch Settings and affect AutoTakeOff to one flight mode position.
AutoTakeOff settings can be displayed in PFD where the small magenta squares are targets for velocity and altitude.
For safety reasons, before the AutoTakeOff sequence is started the velocity is set to a negative value.
How to use
In normal condition you should follow this sequence:
- Switch to AutoTakeOff flight mode,
- Arm with the Throttle stick to minimum (at this point the current altitude is recorded),
- Increase the Throttle value to middle range.
After a small delay the motors start and the take off sequence is started.
When the target altitude is reached, the multirotor go to PositionHold mode.
Please note: You should not switch to AutoTakeOff flight mode while already flying and using 15.09 release.
Basic: Velocity and Height
When engaged, the autotakeoff feature records the current altitude position and add the height to define a altitude target.
Values of height and velocity can be set.
Go to System tab, under UAVOBrowser and search for Settings > FlightModeSettings
- AutoTakeOffVelocity is 0.6m/s by default,
- AutoTakeOffHeight is 2.5m by default.
Please note the minimal height is defined to 2 meters and maximum height to 50 meters.

Advanced: Vertical PIDs
Go to System tab, under UAVOBrowser and search for Settings > VtolPAthFollowerSettings > AutoTakeOffVerticalVelPID
