I have a RC model airplane capable of carrying max 800grams payload (after all my onboard electronics, batteries, GPS, video camera). I want to try auto takeoff and landing. Especially for the auto landing, it important to be able to determine the slop of the final landing approach. For this intended application, I need to accuratelly determine the height of the airplane. (The static pressure sensor alone is not accurate for this).
So, the obvious question;
- Do you know any range/distance/height/altitude sensor with the following features; * LIGHT WEIGHT * Low power (and hopefully low cost) * Measurement range 25m-25cm * Measurement resolution (better than) 10cm * Measurement rate 10 Hz
And also
- Would you suggest any method that helps to line-up the airplane with the landing field (runway). (Currently I'm planing to use the GPS data but it seems to be not very accurate.)se
Cheers,
Falco
