And as you indicated, timing is everything here. You get your slot
to send the data.

I thought I read somewhere that it was a polled system, where the
satellite tells the stations when their chance is ?


Well, following the links I found this:

http://www.nws.noaa.gov/oh/hads/internal/

Check section 1. As I undestand it from my very very brief reading you have timed messages and random messages, but none of them is polled.

I'm sure someone can do a more serious homework than I just did.

Cheers,
Magnus
