[gpsd-users] Get fix mode with disconnect antenna

[Yakov Shmulevich]

Hi,

I am getting GPS data via shared memory export supported by libgps and try to get GPS data every ~1.5 sec.

But also then I disconnect antenna the gpsdata.fix.mode value is equal MODE_3D (3).

In main all gpsdata.fix (accumulated PVT data) is old and not updated.

At the same time the gpsdata.satellites_used = 0.

So, the question is how I can know that PVT data is wrong?

Thanks,

Yakov
