Odd thing happened flying in Northern France last Sat, the yellow plane in the virtual radar would suddenly nose hard down and then after a few seconds nose hard up, so the log shows a series of about 10 step changes in a 1hr flight. My plane didnt change height. It was running on a Nexus7, latest android, never seen it before and flown quite a bit recently. Garmin Aera GPS didnt flinch. All I can think is that the nexus GPS was getting a poor signal maybe being jammed by some interferrance and was getting height errors.

Yep, it's the nature of GPS. An external GPS may help.
