Flying the Mini 4 Pro Indoors - ATTI Mode or Other Tips?

[Dogpilot]

All I can say is my system works quite well. I actually own and use one, I do not depend just on the web, but actual experience. I have been using it since 2017, now with several generations of drones. Notice even your quote says usually. If it was using only the VPS it would tend to drift , since the carpet provides little texture data. I have tried testing my drones during the winter indoors. The 2-3' of snow pretty much eliminates any GPS signal. When the drones try flying just by VPS they drift and do not maintain a steady hover, at least in my home with the very neutral beige carpet. Being a geologist I have a lot of survey equipment, some ground based some airborne. I Also own a D-RTK-2 system for the enterprise drones and a Emild Rover for field ground truthing. I am pretty up on casting gps data.

It will be interesting get confirmation of whether the handheld shows different coordinates as you move around.
I can't see how it could and believe that the repeater could only relay the coordinates of its outdoor location, which makes me wonder what the purpose of such a device would be.

Please turn all the lights off, and repeat your flight in complete darkness, and report back, while checking the handheld GPS coordinates during the flight.

Your repeater can only relay the coordinates of the external GPS antenna, which is only designed to simulate a single GPS signal location for testing purposes of avionics indoors, and is not designed for navigation indoors.

I am not disputing your ability to fly indoors without GPS. DJI drones do quite well without GPS indoors in well-lit areas within 30 feet of the ground.

However, they cannot fly well in the dark without also receiving GPS. A repeater will only transmit the location of the external antenna, which will not help with supplying the necessary changing GPS coordinates of the drone inside for GPS navigation.
