With the upcoming release of Ardupilot v2.1 requiring a 328 based board I have been thinking what i can do with my 168 board. One thing i have noticed is there seems to be a large demand for a cheap tracking antenna from both the FPV and UAV communities.
Unfortunately I lack the technical knowledge/skill to build a tacking antenna but from what i have seen, there are many gifted programmers/developers here. Perhaps it wouldnt be too hard to modify the Ardupilot v1.0 code?
Here are a couple of thoughts on how I see a tracking antenna working:
-The tracking antenna gets aircraft's coordinates from the NMEA sentences transmitted by an Xbee modem (this hardware would already be in place if you are using a laptop labview based ground station) I'm not sure what could be done if the Xbee modem went out of range of the GS.
-Either input the "home" coordinates in the sketch before use or connect the Ardupilots GPS each time when setting up the base station.
-Hobby servos are generally limited to 180* rotation, perhaps two servos could be used on top of each other (think twice the rotation speed for close distance tracking) or a stepper motor could be used?
Does anyone have any thoughts on this and are there any of you interested in developing such a system?
