"When you're doing the test how many satellites are being received? If you're close to the aircraft, multipath issues with buildings nearby can pollute the solution and cause errors in pointing also. If the errors are consistent, it is also possible…"

"I've only tried this on the APM.  I don't have any 32 bit hardware so although in principle it could work, I'm not sure. Also, there well could be Mavlink changes since this software is so old.

"The only way to do this would be to expand the range of the tilt servo to more than 90 degrees and to calibrate it. This requires modifying a number of hard coded constants in the Ardustation code. 

I've stopped working on the Ardustation code, but…"

"You certainly could make it work, but you'll still need some way to set home position using a user interface. The existing Ardustation 2 software assumes that there are an array of buttons and an LCD screen.  The software would have to be modified…"

"It is possible, but there are a few differences that need some work - such as the switch input - which is quite a bit different and the LCD which is larger, and has graphic modes. It would definitely be a better choice - particularly since 3DR has…"

"You could add code to master a couple of I2C slaves, and it is possible with some external wires on the Ardustation (need to add pull up resistors for I2C), but it will be tough to debug with the limited debugging features of the Ardustation. If I…"

"This is a very old version from 2010 so it needs an earlier version of the Arduino environment to be compatible at the library level. I just tried downloading and compiling 2.0.11 with Arduino.021 and it worked.

"Hi Michael,

It is definitely possible, but a little tricky. The current code computes a range bearing to the destination A/C and the bearing is always in 0 to 359 degrees. The default configuration is a standard 180 degree servo geared to an…"

"It certainly is possible since the APM has servo outputs and can process telemetry data on one of its serial ports.  The problem is that no one I know has written the software to do it. Also there is a question of a user interface if this isn't…"

"An LA is a logic analyzer - such as this:
