Zero coordinates problem

Good day! We have a some problem - some trackers losing GPS signal and sending zero coordinates. So, vehicle track is unreal - from Kazakhstan to zero-point (0.0000, 0.0000) of the Earth and back ))). Is any option to solve it?

Thanks!

I was just about to post this same question.

My device sends zero coordinate because most GSM providers in the USA block geolocation info on their cell towers by setting them to 0,0 - which it falls back on with loss of GPS signal. Is there any way to avoid this behavior?

You can filter zero coordinates. This have been discussed many times before.

Thank's. Go to RTFM )

I should also note these 0,0 locations often have useful information embedded, such as notifications, battery levels, etc, so I don't want to discard them. I just don't want them mucking up my location.

Will filter.zero also dump non-coordinate information? Is it possible to just remove coordinates and otherwise process the message?

No, it's not possible.
