Does Home Lock and Course Lock need GPS?

[Phil-RCGeeks]

For the IOC modes, do you need a GPS signal?
I understand you'd need GPS signal for POI and waypoints but my question is, do you need a GPS signal to use Home Lock and Course Lock? For example if you are flying indoors.

Yep of course.

All Intelligent Navigation (IN) modes selected by the F-GPS switch position use GPS.

Got it. Cheers for that
