MAVlink and Linux

I've just started a similar search. Which is somewhat complicated by the fact that google indexes every bleeping transaction on the mavlink github site, so there's a huge amount of noise to sift through.

Basically, I've got a Linux SBC that's monitoring a bunch of security sensors. When it detects a possible intruder, I want it to upload a canned script to the Arducopter that says "Fly the camera out to sector 7, do a search pattern over the area, and return to base". Later on we may want it to get more sophisticated (like tracking the copter's location in real time), but that's it for now.

That SBC doesn't even have a monitor, much less a GUI, so options like running the Mission Planner are out of the question.

So far, I've found two possibilities with some promise:

1. Mavproxy is a simple, command-line-based GCS written in Python.

2. Ardustation is an Arduino app that monitors the incoming mavlink stream, and does status display and antenna tracking.

Ardustation seems to have some limited mavlink encoding and decoding. Since I'm developing the security system in C, I'm first going to look at using that as an example for communications code. But I might also run a modified version of Mavproxy as a separate process, and have the alarm code send it higher-level commands (like, say, "scan sector 7") via a socket.

I have been wanting to make a Raspberry Pi running the http://qgroundcontrol.org/ but I dont have a Pi to test it with.
