I've been using SD on a Samsung Android device to record position of a prototype aeroplane on a flight test programme, then Google Earth to analyse the data. Quality is good, and utility is good - also unlike just about every other app I've tried to use for the purpose, if I minimise it to use my device for something else, SD keep's recording - vital if I'm trying to use it to obtain flight test data. SD is recording position at about 0.2Hz, which for most purposes is absolutely fine. However for, say, working out the exact moment an aeroplane leaves the ground (and thus allowing me to split the take-off roll from the airborne segment) it's a bit coarse. In a perfect world I'd like around 10Hz, but even 1Hz should be quite adequate for my purposes. Is there any way I can alter the frequency at which SD is recording position? Thanks in advance if this might be possible. G²

You can't change the frequency of recording in SkyDemon, although we do increase from 0.2hz when there are significant changes in certain navigation data including speed and track. There's probably some other app you could get whose sole purpose is to log GPS data, though, I would have thought.

Is there any way you can suggest of gaming the system to increase the recording rate to 1Hz?, that would itself be a great help. If not, I'll return to the problem of getting other apps to stay running in the background. G²

Have you had a look? I'm sure you'll find SkyDemon records at more than 0.2hz as those parameters change.
