[Canberrauav] Thanks for your help again Moss, Andrew Andrew.Moss at ed.act.edu.au Sat Aug 31 19:22:23 UTC 2013 Hi Tridge, Thanks for your help again yesterday. We do have alot to do over the next couple of weeks. Hope we can get it done. I have been looking at Autopilots for the UC team. Is it worth buying the PIXHAWK for them? Are there any new GPS's on the horizon that are worth getting? Best regards, Andrew -- This email remains the property of the ACT Education & Training Directorate.

For OBC use the key question is whether the Pixhawk will meet the "separate power supply" requirements of the OBC for the failsafe/termination. As I've also had questions from other teams about using Pixhawk for the OBC I've sent a query to Jon Roberts about whether we could get some clarification on that. The OBC failsafe/termination requirements were one of the design criteria for the Pixhawk, but it meets them by using a power control chip that does a lot more than what the OBC needs. The question is whether the OBC organisers will accept this more sophisticated solution to the problem of ensuring the failsafe board keeps running in the face of failure of other components. So for now the conservative approach with regard to the OBC rules would be to use a PX4 version 1 and cut the power pins between the two boards, so they are completely separated. It would be better engineering to use the Pixhawks solution, but we'll need to see what the OBC organisers say before I could recommend it to other teams without running a risk of it being rejected in D2 or scrutineering. Cheers, Tridge
