    Radar at that great distance with such precision is amazing.

    I've read that it's primarily radar. I don’t think there’s a terrestrial telescope that can see D12. After a quick calculation it seems that it would have to have 10x the resolution of the Hubble...I think. :grin:

    You will find the info you want here. He maintains a service for satellite operators that advises them on collison avoidance.

    Doppler tracking is very, very accurate as well. Add in the accelerometers and star trackers that are generally part of a satellite bus for GNC, it's fairly easy to come up with accurate tracking data for professionals. The amateurs who do it for classified recon sats have to do it the old fashioned way with precise observations and angular velocity estimates.

    I believe speculation is new LNBs no matter what...

    I believe they use the Space Fence

    Please don't tell us we tax payers' spent hundreds of billions only to have amateurs do the work with old fashioned tools, if so I want my money back.

    I think it's more amateurs trying to keep track of what the Government is up to. Or just a hobby to try to figure it out. But with the way things are, it may be up to an amateur to find that there's an asteroid on a collision course.

    The very first synchronous satellite, Syncom I in 1963, had a postlaunch failure but nonetheless ended up at 22,300 miles with a 31 degree inclination. Although it was much smaller than D12, it was eventually spotted via telescope (it had the Clarke belt all to itself for several months).

    Flat, a couple feet tall, and you can crawl under it easily?

    But what can you see beyond a dot, and only at certain times of day, and you probably can't be very accurate in positioning...all a guess but I gotta believe that radar would be much more accruate.

    At least don't put up that fence until after Cinco de Mayo is no longer observed, or after D12 is found, can you imagine us Americans with beer bellies forced to crawl under it just to have some fun south of the border?

    Great news that D12 is drifting! Had some more good news today, our local translators are going HD early next week. I will finally get to see our local channels in HD! I figure after all this waiting and finally getting locals in HD OTA, DirecTV would now announce that DMA 131 is one of LiL HD markets they will be adding once D12 is in full operation…

    Let's first not forget to slow it down:) The faster the speed, the more likely we may over shoot it, I learned it the hard way a few times when I rushed too much and missed the final exit, ended up on the other side of the bay:)
