Cannot see landing_target_estimator in QGroundControl

[zquang]

HI all,

I am testing the Precision Land modules using IRLock sensor.
I was able to test in Gazebo simulation (make posix_sitl_default gazebo_iris_irlock). I can takeoff and auto:precland in the simulator. In QGC, it is possible to change parameter of "Precision Land" and "Landing target estimator"

I compiled the latest FW for Pixhawk 2 (Cube) from source (make px4fmu-v3_default) and upgrade FW in QGC. I can see parameters for "Precision Land" but cannot see "Landing target estimator".

As far as I know, "Landing target estimator" get information from IRLock sensor (Pixy camera) then output x-y offset of the landing target. It seem that this module is missing in the "real" FW.

Many thanks

The estimator is included, but not started at boot. You will need to modify startup scripts or add an extras script on the sdcard.

the latest QGroundControl can not get params in Gazebo simulation ,do you have this problem?

I use QGC binayry installation from https://s3-us-west-2.amazonaws.com/qgroundcontrol/latest/QGroundControl.tar.bz2
It can get params from Gazebo, but not from real Pixhawk 2 (FW development version)

(For anyone having a similar issue)
I found that in QGC you have to go to the MAVLink console and type landing_target_estimator start and then you are able to see all of the irlock params. I was using a Pixhawk 2 (BlackCube).

In order to get this to start on boot...

• Take the microSD out of the cube
• Put it into your computer and open its location in the file explorer
• Create a folder called etc
• In that folder create extras.txt
• In that text file write landing_target_estimator start and save it
• Plug it back into the cube and it should start on boot!
