sun position calculation

[BBC5]

My external GPS receiver antenna works fine on my win10 system, but doesn't seem to be recognized with the sun position calculation (and NTC).

What I see is that the GPS led will light briefly when I try the sun position calculation (and NTC), but the sun position calculation and NTC doesn't work.

What should I check?

According Qt documentation this will work: with GPS receivers exposed as a serial port providing NMEA sentences

Is there a way in qdd to specify a com port for the sun position calculation/NTC?

I am getting NEMA sentences at my com port. (see attachment)
