My name is Oyvind and I am one of the founders of Intelligent Agent (www.intelligentagent.no). We are a startup that develops radar technology for robotics.
We want to make radar technology available for UAV developers and are considering the possibility of offering a radar altimeter. We have most of the technology readily available and won't need too much time to finish a working prototype.
To get some input, I would like to start a discussion here to hear from you guys what your thoughts are on this.
What do YOU use an altimeter for? To keep a certain distance above ground? For autolanding? For avoiding collision with ground? Other?
And what is important for this application. Is it long range? Is it accuracy? Resolution?
I suppose there are really two kinds of UAV markets: the diydrones community hacker kind and the professional user who just want a closed box.
The thing is, I think, the user wants a complete quad that works out of the box, so doing an open source hackable version or both of them seems like a good idea.
200 - 300 grams is ok for airplanes but is can be a bit heavy for a quad I think, would it also be possible to mount certain expensive parts separately and have only the dish outside? When a plane crashlands for example there is a lot of stress on the wings, you may not want sensitive components there.
It would be possible. It's a good idea and I'll keep that in mind.
