Hi there,
I don't know how important this is, but it seems to me GPS Signal strenght is depending on the tilt angle.
Wouldn't it be great to have a GPS gimbal that automatically keeps the antenna level, no matter how hard I'm wrestling with the sticks?
This gimbal wouldn't need servos or motors, it would work with gravity.
I made a quick&dirty sketch to show what I mean, but this drawing is just a concept and needs a bit engineering to make it work by gravity.
Anybody feel free to come up with a sellable solution. I'm just asking for a free sample.

Re: autoleveling GPS gimbal
Interesting idea.
However, I see that some amount of damping would be required so it does just keep swing after a quick angle change.

Re: autoleveling GPS gimbal
You're right waltr,
I hope the gps cable and cheap bearings would add some damping. The design should prevent a complete flip of the antenna too. ( cable lenght?)
If I had a 3D-printer, and a CAD program.....

Re: autoleveling GPS gimbal
Instead of waiting for Santa to send me a 3D Printer, I decided to go the classic balsa_glassfibre_sandwich jigsaw puzzle way.
To make the gimbal fit onto my crius AIOP FC, the frames get pretty small.
I came up with the idea to solder a single brasstube onto the copperside of the glassfibre. This way alignment is easy.
The intermediate frame has to be perfectly square and will be rotated 90° after sawing it out.

I finished my " McGyver"-Version of the gimbal.
It still needs some adjustment, like CoG-adjustment and some shims to avoid friction between the frame parts, but it works pretty neat
Where are those chinese copycats, when you need one?

Look good.
Now for some testing and a video on response and damping.
