Nick,

I think there are a couple of satellites older that still transmit, but AO-7 is, I believe, the oldest satellite that still serves a useful purpose.

Hi, I know this topic has been debated for some time, but I believe by just looking around the Wikipedia and google, AO-7 would have to be the longest operating satellite around earth. All I have seen people mention is GOES 3 and ATS 3, but never once AO-7.. Even if it was silent for 21 years, it's still technically the longest operating satellite. Can anyone else confirm there are no other satellite older than it still operating? It's kinda hard to find a current answer because it's always changing, and you have to scavenge the internet. If so it would be awesome to think a low tech, ham built satellite would beat a commercial, million dollar satellite... 73's KE8AKW _______________________________________________ Sent via [email protected].
