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?
