Come on guys.. We all know that them there GPS satellite thingies are scared of the Dark.."If you took off at night there is a danger that your RTH point was not recorded. "
I was curious about this too?

The only way you could not correctly record the home point would be to launch before getting GPS.If the home point hadn’t been recorded correctly, the drone would have made off (if it could) to whatever homepoint it had in its memory.
Wrong! I just turned on my drone and connected. Got green to go with no GPS lock and the map in Go4 changed from the position of the controller, in this case literally my home, to the home point at my last flying position about 8 miles north west of my current position. So if I’ve not flown for a while, the AGPS data might be out of date, and need downloading before the drone acquires GPS lock and home point reset.The only way you could not correctly record the home point would be to launch before getting GPS.
If you were to do that, your Mavic would still record a home point and it would happen when it got GPS reception, probably fairly close to your launch spot which would have no impact on the flight at all.
Since the stored home point evaporates when the drone is switched off, the only home point it could have stored will be the correct one.

Sar is correct.Wrong! I just turned on my drone and connected.

Ok, so the old home point isn’t overwritten in Go4 until gps lock is attained. I never fly until I’ve seen the drone icon and RC position overlaid in the correct orientation at the correct location.Sar is correct.
To confirm what I said.
Check the recorded flight data and it will show a blank field for the Lat and Long until you get GPS reception.
I've checked the data from hundreds of flights al over the world and they never start with an old home point.

More to the point is that we’ve heard nothing from the OP for days and he can’t be bothered to post the logs that will tell us definitively what caused the loss of the drone, even though he’s a regular viewer of this thread.
The old home point record doesn't exist after you shut down your Mavic.Ok, so the old home point isn’t overwritten in Go4 until gps lock is attained.
In a few of my 274 flights I’ve had signal strength drop off and been able to regain it by adjusting the antenna orientation and I still have my original drone, so I think I’ll just carry on doing what I’m doing.Luckily i have never lost a signal (in my 15 ,16 flights)
i never adjust my Antennas...i point them UP and so far i have never lost a connection (i would be very upset if i did as i am constantly concerned with the possibility of a fly away or a loss of signal while flying over one of the most populous parts of our country..(NYC ) and the harm that my flying might cause IF this happened..so far,ALL flights have been flawless and for that,i am grateful..

You start again and the home point is blank until it has good GPS reception and records a new home point.
To SAR (who’s knowledge and skill with flight logs I respect) and Meta4, ok I get it, the home point is lost when the Mavic is turned off and there is nothing until the drone gets gps lock. Not the best of programming but not a lot that we can do about it. But we don’t know what happened with the lost drone as the op is not giving the logs that would show what he did or the conditions.
To others that commented on height limitations, my version of Go4 has a maximum height of 400ft above takeoff that has to be altered manually. I also understand that most countries have a recommended max altitude for drones of 400ft to give some separation from manned aircraft who have a lower limit of 500ft.
That’s it. Bye and merry Christmas.
