Thank you very much for your help.
At 6m 30.3s into the flight, the remote controller signal was lost. Since the GPS signal wasn’t strong enough for the drone to auto return to the home point, the drone automatically landed at its current location.
Your flight log shows the drone landed at 20.9818201674668, 105.4023027630152.
Thank you very much for your help, At this location I had find but still not find the drone yet. any locations more may the drone landed
No, the drone was clearly landing at that exact location. If you go to that spot and search within a 20 foot circle to allow for any potential GPS error (which should be minimal), you should be able to find it there. It looks like there may be some trees in that area, so be sure to check up in the branches as well.
plz help me to check At 6m 30.03s to 7m 28.4s the distance I measured with google earth is 3798.81m can the drone fly there (max speed of phantom 4 rtk is 47km/h isn’t it?).
Per the Phantom 4 RTK specs, the maximum speed of the Phantom 4 RTK is 50 kph in P-mode or 58 kph in A-mode.
I reviewed the flight log again and found that GPS was completely lost at 5m 48.2s into the flight. Interestingly, the latitude and longitude continued to be recorded, which is why it appears the drone landed at the location shown on the map above. However, without GPS data, that location data probably cannot be trusted.
At 7m 18.3s into the flight, the downlink reconnected and the drone was auto landing at its current location. It looks like you pressed the RTH button on the remote controller to initiate RTH while the downlink was disconnected. And since the drone was flying in ATTI mode at the time, it auto landed instead. Does that sound right?
Your drone’s RTK module also tracks its location. The yellow “Last GPS Location” pin on the right side of the map below marks where the drone last had a valid GPS signal. Both the GPS and RTK positions point to that location. After GPS was lost, the recorded GPS and RTK coordinates no longer aligned.
In the last record of the flight log, the RTK position shows the drone was at 20.9892261146758, 105.3303332255387. That location is marked with the yellow “Last RTK Location” pin on the left side of the map below.
That said, I’m not entirely sure that position is accurate either, since the RTK module likely relies on GPS data to determine the drone’s precise location.
Yes, after I can not control drone I pressed RTH but fail, the last location that I saw camera image in the remote control at 6m 30.3s after that nomore any information about drone and image. I had find the drone at the place that I marked with red colour at the attach image and the map that I marked, any guest from you, thank you very much.
Map:
At 6m 30.3s, GPS and RTK located your drone here:
Do you know for certain if either yellow pin is in the location you saw in the camera image?
The yellow pin of GPS location is the last camera image I saw.
After that point, the downlink dropped for 48 seconds. As you noted earlier, there’s no way the drone could have reached the next recorded location after that gap. If it had, it would have been flying at 148 MPH, which simply isn’t possible.
If both the final recorded GPS and RTK locations are inaccurate, then I don’t think there’s any reliable way to track down the drone. Since the data can’t be trusted, the only option would be to start walking from where you last believe it was located. But even then, you wouldn’t know which direction it was heading. It was drifting in ATTI mode, or possibly under your control since the uplink was restored at some point.
