just curious

Hey folks,
I've noticed on Sadouns sat list that on a few of them more then 1 sat occupies the same spot i.e. 101 has 2 sats on it.
How does that work? How can 2 birds occpy the same space??
Thanks

I always liked this chart from boeing to illustrate what satellites are where. They keep it up to date somewhat.

Satellites are not that big and they can be near each other and occupy the same orbital slot.

I like how you can ZOom in on the satellite positions : )

I had no idea there were THAT many sats up there! Amazing! :shocked

back to the original question

DBS satellites have frequencies from 12.2-12.7
KU band is from 11.7-12.2

So since they dont clash in frequencies, there can be 2 or 3 satellites at one spot (note theyre not exactly at the same spot in orbit...but when they come down 22000 miles, its near the same spot)

Look at 91...there are 3 different bands there
C Band and KU band on Galaxy 11
Nimiq 1 & 3 have the DBS slots split up.
