What is a GHOSt satellite?
GHOSt (Global Hyperspectral Observation Satellite) is a planned earth observation constellation by Orbital Sidekick. The custom payload will produce the highest resolution commercial hyperspectral imagery launched to-date with a GSD of approximately 8 meters.
Do satellites have beacons?
Most of the satellites have a beacon. They are normally at the top or bottom end of the frequency spread for that satellite. Some have two beacons.
Do satellites use telescopes?
Astronomers use a number of telescopes sensitive to different parts of the electromagnetic spectrum to study objects in space. In addition, not all light can get through the Earth’s atmosphere, so for some wavelengths we have to use telescopes aboard satellites.
