Can a system be set up to position an APM2 board in space with an accuracy of +/- 5 mm?
The board will be used at a controled site, and I was envisioning the use of
"positioning transmitters" - a local & very high accuracy wireless positioning system
"replacing" the GPS.
The board will need to flash some LEDs or BEEP when at the required point and alignment
And no - it will not be flying.
