It is indeed the perceived GPS signal quality that creates this problem at altitude.
Should the same iPad be used from takeoff onward, the issue in cruise may not be apparent.
The initial GPS location acquisition needs to be made, something any Apple device has trouble with when attempting it in cruise. Once acquired, it works a dream.

Recommendation for using an external GPS is so you do not need to rely on the iPad GPS internally, which creates this problem.

Solutions for now:
1 - mount Pad and have it receive GPS signals from departure onwards;
2 - use external GPS;
3 - have Apple improve its GPS location acquisition at altitude and speed, maybe as a software fix, if not a hardware fix for next generation iPad.
