ARLA/CLUSTER: Estados Unidos encerraram radares de deteção orbital em 216 MHz

US Space Fence shut down

It is reported on SatWatch that the 216 MHz US Space Fence, used to
detect orbital objects, was shutdown on September 1, 2013 at 0000 UT

The Space Fence is a U.S. government multistatic radar system built to
detect orbital objects passing over the United States. There are three
transmitter sites operating on 216.983, 216.97 and 216.99 MHz and six
receiving stations.

According to Wiki the system is understood to be capable of detecting
a 10 cm object at an altitude of 30,000 km and makes 5 million
satellite observations each month.

Early in August Space News reported that: Gen. William Shelton,
commander of Air Force Space Command, “has directed that the Air Force
Space Surveillance System be closed and all sites vacated” effective
Oct. 1, the memo said.

However, it appears that the shutdown has occurred earlier.

The reason for the shutdown is believed to be because the Federal
Government is spending more than its budget resulting in automatic
budget cuts known as sequestration.
