Probably not necessary since you won't get GPS under all that concrete. There's no need to calibrate the compass, because the drone never loses its calibration. DJI's warning is badly worded and confuses users. It's telling you that the compass sensor is detecting a magnetic field greater than...

Not a bit. No previous solar maxima have caused problems for drone flyers, so it's unlikely this one will be any different.

You can't install 3rd party apps on the GL300E controller. But if you can find a GL300F controller, you can use that with the drone. You would also need to buy a tablet or use a phone with the controller.

The launch isn't the real problem. It's where you power up the drone. That's when the gyro sensor gets its initial values from the compass.

Many drones have been lost because they were powered up on a reinforced concrete surface where hidden steelwork was close enough to the compass sensors to deflect the compass giving it a false reading. If the magnetic field is stronger than what the drone is expecting, it will bring up a compass...

There are two reasons that this is ringing alarm bells for me. There is no need to recalibrate the compass before a flight. That you are, indicates a poor understanding of what compass calibration actually does (and doesn't do), and when it might be needed (almost never). There was nothing...

400 ft is too much clearance above terrain for most flying. It would mean an unnecessary, battery-wasting climb and possibly put the drone up in higher level winds that could be another issue. It's better to set an RTH height to suit wherever you are flying and whatever obstacles are there. It...

Click the CSV link that's below the map image on the Overview page of your Airdata report.

The actual recorded data shows much more than Airdata's brief summary.

The recorded data shows the number of sats dropping to zero briefly a few times after 261 seconds. And after 296 seconds it drops to zero and stays on zero for the rest of the flight. The maximum number of sats acquired was only 13, which is very low for a P4 pro, which typically finds 20+ sats...

How old is the battery ... how long before flying was it charged? The Go 4 app allows you to check the battery like this: The recorded flight data from your flight incident will help find the explanation for your issues. There are a couple of options ... 1. Go to DJI Flight Log Viewer |...

You can achieve accuracy of around a foot without GCPs or RTK. With GCPs you can bring that down to a couple of inches. How much accuracy do you really need? I really doubt that you need centimetre level accuracy for habitat surveys.

Not sure where that idea came from .. it's not true at all. If it was you could only ever map very small areas. You drone can acquire mapping images as it flies along at 20-30 mph.

Your GPS count went as high as 10-11 for only 6 or 7 seconds during the flight. That is quite a bit lower than a P4 pro should receive if it's got a clear view of most of the sky and you haven't mounted an accessory on top of the GPS antenna. Singapore is a very vertical city with tall buildings...
