Long-Lost US Military Satellite Found By Amateur Radio Operator

Tilley, an amateur radio operator living in Canada, found a "zombie" military satellite that was supposed to shut down in 1972. NPR reports: Recently, Tilley got interested in a communications satellite he thought might still be alive -- or at least among the living dead. LES-5, built by the Massachusetts Institute of Technology's Lincoln Laboratory, was launched in 1967. Tilley was inspired by another amateur who in 2016 had found LES-1, an earlier satellite built by the same lab. What was intriguing to him about LES-5 was that if it was still working, it might be the oldest functioning satellite still in geostationary orbit. By scouring the Internet, he found a paper describing the radio frequency that LES-5, an experimental military UHF communications satellite, should be operating on -- if it was still alive. So he decided to have a look. "This required the building of an antenna, erecting a new structure to support it. Pre-amps, filters, stuff that takes time to gather and put all together," he says. "When you have a family and a busy business, you don't really have a lot of time for that," he says. But then came the COVID-19 pandemic. British Columbia, where Tilley lives, was on lockdown. Like many of us, suddenly Tilley had time on his hands. He used it to look for LES-5, and on March 24, he hit the ham radio equivalent of pay dirt. While Tilley thinks it may be possible to send commands to the satellite, the MIT lab that built LES-5 didn't comment on the matter when NPR inquired.
