This machine has not failed to execute PH, RTH or missions since we fixed SBAS months ago ---- until today.\r\n\r\nResult. Completely random PH behaviour (if PH fails, then I don't even try any other nav function).  Randomly, on hard reset, nav functions will either work or fail. Some log files at \r\n http://seyrsnys.myzen.co.uk/inav_ph_woes/. All the log files were created in a short time frame with good satellite coverage (16-19) and good HDOP (1.1 - 1.3).\r\n\r\n- LOG00279.TXT: 85fe245. PH fails miserably, repeated.\r\n- LOG00280.TXT: f440ead (having persistent mag/acc makes checkout / build / flash / apply config in the field so easy:). Works OK.\r\n\r\n... does some betaflight stuff on the minis for 30 minutes\r\n\r\n- LOG00281.TXT: f440ead: nav functions fail miserably, repeatedly (multiple arm / disarms)\r\n- LOG00282.TXT: f440ead: *powercycle* nav functions work again !!!!\r\n- LOG00283.TXT: f440ead: *powercycle* nav functions still work. Out of lipos, otherwise I'd have tried 43eaf10 (which behaved perfectly across multiple lipos earlier in the week).\r\n\r\nNote 0. LOG00281 Index 1, PH attempt 4 is a good example of 'fly off' ![selection_473](https://cloud.githubusercontent.com/assets/158229/17458870/3318c644-5c1a-11e6-9f85-7fac90c42b86.png)\r\n\r\nNote 1. 281-283 were executed in quick succession, it is unlikely that there was some environmental change that affected the results.\r\nNote 2. If PH is not (obviously, visually working), it is rapidly aborted.\r\n\r\n**Exec Summary** : nav post 43eaf10 seems pretty random to me at the moment. Other experiences solicited.\r\n\r\n\r\n\r\n\r\n"},"comment":{"url":"https://api.github.com/repos/iNavFlight/inav/issues/comments/241840684","html_url":"https://github.com/iNavFlight/inav/issues/431#issuecomment-241840684","issue_url":"https://api.github.com/repos/iNavFlight/inav/issues/431","id":241840684,"user":{"login":"martinbudden","id":194586,"avatar_url":"https://avatars.githubusercontent.com/u/194586?v=3","gravatar_id":"","url":"https://api.github.com/users/martinbudden","html_url":"https://github.com/martinbudden","followers_url":"https://api.github.com/users/martinbudden/followers","following_url":"https://api.github.com/users/martinbudden/following{/other_user}","gists_url":"https://api.github.com/users/martinbudden/gists{/gist_id}","starred_url":"https://api.github.com/users/martinbudden/starred{/owner}{/repo}","subscriptions_url":"https://api.github.com/users/martinbudden/subscriptions","organizations_url":"https://api.github.com/users/martinbudden/orgs","repos_url":"https://api.github.com/users/martinbudden/repos","events_url":"https://api.github.com/users/martinbudden/events{/privacy}","received_events_url":"https://api.github.com/users/martinbudden/received_events","type":"User","site_admin":false},"created_at":"2016-08-23T19:00:07Z","updated_at":"2016-08-23T19:00:07Z","body":"Great, thanks"}}
