I been flying and noticing it doesn't show D values sometimes, and the Flight Record shows 0 Distance, even tho Altitude is over 20m and several minutes of flight. What can that be?

This is possible when there is no GPS

It was from 6 to 11, poor signal. But hardly "no gps"...

This is not enough, look at the top corner for the GPS icon, if it is not white, then the drone is not using GPS to maintain position.

I see! Fair Enough. I saw some having the same issue, and this actually makes sense.

For your drone to get good GPS position information, it needs two things.
1.  Enough sats
2.  Sats must be spread far enough apart in the sky.
10 sats bunched in a small part of the sky don't give location data like 10 sats spread across the whole sky would.
Flying where a large part of the skyview is blocked by tree cover, buildings or terrain, you may have trouble getting enough sats AND a good spread of sats.

6-11 sats is a very low number of sats when your drone would be picking up around 30 in an open area.
With only 6-10, it's likely that were bunched close together in a small "window" of sky.

As mentioned above, the number of sats isn't the most important thing.
Watch the sat icon and when it's gone from red, to yellow and then to white, the app is telling you that you have good GPS data.

Hi there. Thank you for reaching out and we do apologize for the trouble. Please try to fly to a different location with a strong GPS signal to further isolate the issue. If you still experience the same issue, kindly reinstall the APP (if you are using the DJI RC-N1 with a mobile device) then check if there are changes. Please keep us posted.
