Hi!
@ThomasSFL
I have a problem when I use the skycharge base with the IR-LOCK precision landing. IR-Lock use a beacon on the floor and a camera on the drone, and on the ground works perfect! But we area having issues at mid day, when the sun its over us almots 90° to the ground. The SkyCharge base reflect the sun like a mirror, and to the eyes of the camera, the beacon its dificult to see. Here its a picture from the problem.

Thanks!

I have never used IR Lock but I am curious if you can get a polaroid filter in front of the lens. That’s what we use in photography to stop this problem.

Good Day,

You should not use mirror-like surfaces directly behind the MarkOne Beacon.

It is best to use matte (non-smooth) and NIR absorbent (typically black) surfaces. Some reflection is ok, but a large mirror-like surface is definitely not good to use directly behind/beside the beacon. It will oversaturate the sensor in the area of desired detection, which results in zero detection if that is where the beacon is located.

Best,
Thomas
