No GPS warning with full GPS?

djiuser_UOmYJok8Lpfl

So I get a no GPS warning even though it appears to have good GPS reception. Anyone knows what is causing this?

Seems interesting. It seems like it's only possible to check after 2 days.
But if it's actually jammed won't it show 0 on the satellite number? Besides m3p is supposed to support GNSS and BDS. So is it possible that all 3 are jammed?

LV_Forestry

There are several forms of jamming.  One consists in transmitting valid but out of phase GNSS signals.  The receiver sees the sat, but fails to calculate a valid position.

I see Israel under your nickname, wouldn't you be close to a complex of the Elbit company?  They are specialists in this sort of thing.

GNSS is the global term for GPS, GLONASS, Galileo, BDS, QZSS and IRNSS.  Yes it is possible to jam all 6 at the same time.

I'm well aware of elbit IAI etc I keep away from that kind of facilities. As far as I know there is nothing sensitive in that area

DroneApe

They can flip it on and off just like the light switch in your bathroom.

But his suggestion had nothing to do with that incident.
Read my analysis in the same thread to see what really happened.

No ... You can check the recorded flight data anytime after landing your drone.

But if it's actually jammed won't it show 0 on the satellite number?
Usually

Besides m3p is supposed to support GNSS and BDS. So is it possible that all 3 are jammed?
Yes .. it's possible.
If you had GPS satellites still being reported, it's likely that you had a similar issue to digibud.
Post your flight data and I can look into it for you and see what was happening.

Hi, djiuser_UOmYJok8Lpfl. Thank you for reaching out. Please refresh the firmware version of the drone and RC using the DJI Assistant 2 (Consumer Drones Series). You may download it from this link: (https://www.dji.com/downloads/so ... sumer-drones-series). Make sure that the DJI Fly is in the latest version as well (V 1.10.1). In addition, please fly the drone in an open area without any possible interference to have a try. If the issue persists, please provide us with the following information below:
1. Screenshot of the firmware version
2. Flight controller data and the flight time
3. App Log and the time when the issue occurs

For Flight Controller Data Export:
Step I: Please connect the aircraft to a computer with a USB-C cable. Launch DJI Assistant 2 (Consumer Drones Series). Tap the Aircraft icon.
Step II: Go to the Product Page. Select “Log Export” on the left menu. Then, select the required time point data and finally select “Save to Local”.
Step III: After “Download Complete” appears, it indicates that the data has been saved locally.
Step IV: Then save the .DAT file format.

For DJI RC App Log Eport:
The app log cannot be exported by directly connecting DJI RC to access the file folder. Please try connecting DJI RC to DJI Assistant 2 (Consumer Series) to export logs, and the app log is included in the log exported from the software.
Method: After DJI RC is connected to DJI Assistant 2 (Consumer Series), click “Log Export”, select the log to be exported, and click “Save To Local".

Please keep us posted. Thank you.

Hi,

this is not a flightlog.

What color was the GPS indicator on the remote itself, and not in the flight log? I was in a poorly accessible place, with the number of satellites 22, the indicator was yellow and the system reported that there was no GPS. In the flight log, I also did not have a full GPS signal.

GPS quality shows only 2, thats quite low

Scroll page to left.

Perhaps it's your phone or controller that has no fix. If you are using the old N-1 controller, with a phone attached, be sure location is enabled . And/or check your phone in a mapping app.

Posting just 4 lines from a spreadsheet with thousands of lines of data isn't very helpful.

There is GPS jamming in your part of the world as you can see here:
