Re: ARISS events

ISS is just like any other satellite when it comes to Doppler. The
satellite does not adjust its frequency. ISS transmits on 145.80 and
each ground station adjusts their Doppler according to their relative
position to the ISS.

Hi Ken...

Just a quick question that came to mind after today's school contact...

Do the astronauts know how to or do they adjust for doppler during the
contacts? I know from the ground station that we might be dealing with
+/- 8 kHz up there...do they have "steps" built into their radio?

Thanks and keep up the good work!
