Why position information doesn't show in my display? (In Thailand)

[naratipb]

I can receive ADB-S signal but it doesn't show Latitude,Longitude,Dist and Brg. I try to track Thai airways,British airways(fly over Thailand).Why is it?

Are you saying that you see it in the list, but not on the display?

It true.I can see the list but not see on the display.

Although an aircraft is equiped with ADB-S some do not transmit their position. Military aircraft are one example.

If you look in the list, some will have a globe next to them. These are transmitting position information. Without this information there can be nothing on the display.
