What frequency is Milstar?
The Milstar system provides uplink communications at extremely high frequency (EHF), 44 GHz, and ultrahigh frequency (UHF), 300 MHz, and downlink communications at super-high frequency (SHF), 20 GHz, and UHF, 250 MHz. The crosslinks operate in the 60 GHz region.

Can I launch my own satellite?
You can send your own satellite into space with the help of NASA’s Cubesat Launch Initiative. This CSLI program makes space research more accessible than ever before in history! A cubesat is a miniaturized satellite for space research and commercial use. It’s about four inches long and weighs about three pounds.
What is MUOS USMC?
Initially fielded in March 2019, the system enables mobile or stationary Marines to leverage cellular technology to increase access to voice and data communication. It also improves overall reliability in urban environments. “MUOS gives us a 3G capability using satellite constellations,” said Lt.
Do satellites detect missiles?
The satellites are designed with “improved warning” features to detect missiles that move faster or create a dimmer infrared signature than current systems are designed to track, according to the release.
Who built DSP satellites?
Northrop Grumman Aerospace Systems
Do satellites have weapons?
Strategic Defense Initiative Other aspects included satellites in orbit carrying powerful laser weapons, plasma weapons, or particle beams. When a missile launch was detected, the satellite would fire at the missile (or warheads) and destroy it.
