Drone with GPS data sending problème

Nabil9 days ago

Hello,
We're looking for a type of GPS tracker that can provide decent results even at very high altitudes. From 200m to 4km!!

We tried it with the FMC940, but over 150 meters, no real-time data is sent.

Could you please let us know if other parameters need to be adjusted on this teltonika GPS tracker, or if we should definitely change it and test with other modules.

I did a test this morning, when the altitude of the drone is a little low (20 to 50 meters), the data transmission time is perfect (2 to 10 seconds ). but as long as the drone is raised in the sky, no data arrives even after 3 or 4 minutes of waiting

Thank you so much for your support.

I think most devices should work just fine at high altitudes. I'm surprised that Teltonika is not working. Is there some logs to check the root cause?

hello anton,
thank you for your replay.
in attached the logs as requested:
the test operation for yesterday was between 11h:30 and 11h:45 ( morocco times)
My teltonika IMEI Number is 868373079646479

but I was did some research and discovered that the GSM network (voice + 4G/5G) of any telephony operator does not propagate upwards (it propagates like a pyramid whose head is the top of the pylon).

this means that at high altitudes there is no connection so the GPS tracker is no longer connected!

There are same gps trackers that use satellite sim cards which can work at hight altitude but they are expensive !!

Well, I hope we can find a solution for my case, because I really need it, thank you once again for your help

Help please

I don't know that. That's why I said if it's possible. You should check with your vendor if you don't know.
