Prototype Space Fence Now Tracking Actual Orbital Debris
coondoggie writes "Lockheed Martin says the prototype system it is developing to track all manner of space debris is now tracking actual orbiting space objects. The Space Fence prototype includes new ground-based radars and other technologies to enhance the way the U.S. detects, tracks, measures and catalogs orbiting objects and space debris with improved accuracy, better timeliness and increased surveillance coverage. 'Space Fence will detect, track and catalog over 200,000 orbiting objects and help transform space situational awareness from being reactive to predictive. The Air Force will have more time to anticipate events potentially impacting space assets and missions. Our net-centric design approach allows Space Fence to be easily integrated into the broader U.S. Space Surveillance Network of sensors already operated by the Air Force.'"
The Earth can yell "get off my lawn" and have it mean something.
Seems like a better name would be "SpaceWatch" or something. The word "Fence" implies it can block debris . When I think of tracking I typically don't think of fences.
Still, sounds like a neat project.

MPAA ruled out their first choice, so they use the closest synonyms they could find:
Sky->Space, Net->Fence.
. . . another man calls, "my spy satellite" . . .
As in:
"Hey, you destroyed my spy satellite!"
"Oh, sorry, it looked like space debris to me. I was just trying to tidy up a bit."

This "fence" system, like some earlier fence systems, is called that because it's a bistatic (or multistatic) radar. The transmitters and receivers are at different locations, and the transmitted beam is not steered. Targets are located by time differences between what's received at multiple receivers. The previous system had three transmitter sites and six receiver sites, spread across the US.
Fence systems are somewhat specialized, but a good way to find everything that crosses the fence volume. Once the RF gear is in place, it's mostly a processing problem. Unlike regular radars, there's no useful information without correlating multiple receiving stations.
That summary ignores we already have that!
It only sounds interesting if you A) Don't know that we've had that capability since NORAD tracked Sputnik with similar projects done by every major space administration on Earth, or B) Didn't bother reading the infrastructure proposed.
And now, the troll that has a joke for, "Holy Junk!"

Actually, it's the current, working system. Space Weather has a nice link to a receiver that lets you listen to the echos from stuff flying through the fence http://spaceweatherradio.com/ Or you can do it your self....If you're within several hundred miles of Lake Kickapoo, Texas, and have a receiver that can hear 216.98 MHz, you can hear the echos of things flying through the fence... Big fun if you're a radio nerd :-)
We will soon reach a point where not having such predictive capabilities will doom any launched vehicle to a debris collision. Its interesting to think that such a program provides so much space superiority over other nations.
