NROL-22 (Trumpet 4)
Type: Government/Top Secret
These spacecraft are probably the replacement for the Trumpet SIGINT satellites operating in a Molniya orbit. As no name is known, these are referred here as “Trumpet Follow On”. Possibly these satellites might be named Raven. These satellite most likely use a large, unfurlable dish antenna to collect the signals. Advances in both antenna and electronics technologies have allowed for a large reduction in size compared the Trumpet predecessors.
