This release is for Mavlink changes in ACM 2.9.1. The message location of the number of GPS satellites has been changed for ACM. Ardustation II 2.0.16 will display 0 GPS satellites with 2.9.1.

I’ve also added an additional antenna range/bearing as suggested by James Masterman. He reported antenna pointing issues at long ranges at his location in Australia. This algorithm seemed to fix his problem. I’ve tested both algorithms using a simulation and the results seem to be very close. I’ve left the default algorithm originally provided by 3DR but you can select the alternate algorithm by pressing the center button on the pad while on the antenna range/bearing display. The display will show ALG 1 for the new algorithm and ALG 0 for the old.

I’ve tested the software with my quad on ACM 2.9.1 and an APM 2.5. I have not tested this software with Arduplane 2.7, but I expect it to still work and appreciate any reports of problems by users.

The software is available at the usual spot:

Please be sure to download the zip file to a empty folder and to only use the library folder contained in the distribution. Do not merge this library folder with either the ACM or APM library folders. This software should be compiled with Arduino 1.0.3 or Arduino 1.0.1. Do not use the earlier versions as indicated in the Ardustation wiki.
