  • Space Communication

    There are two types of communication systems: radio frequency (RF) and free space optical (FSO) also referred to as laser communications (lasercom).

    Most spacecraft communications systems are radio frequency based - one part of the electromagnetic spectrum.

    Satellites communicate by using radio waves to send signals to the antennas on the Earth. The antennas then capture those signals and process the information coming from those signals. Information can include:

    • scientific data (like the pictures the satellite took),
    • the health of the satellite, and
    • where the satellite is currently located in space.
