Most early satellite communication operated at C band with relatively low power and low antenna gain. A satellite in geosynchronous orbit circles the Earth once every sidereal day. An orbit determines a satellite's speed as well as its distance from and position above the Earth. Reflector antennas or phased arrays provide the high gain needed by the antennas in a satellite link. A Global Positioning System receiver must have the Gold codes from all the satellites in order to decode the signal. Geostationary satellites are important for weather and communications, because ground satellite dishes do not have to track the satellites. A communications satellite transponder goes by the name of bent pipe architecture. Spin stabilized satellites fire jet thrusters to start the spinning once in orbit. Spin and three‐axis body stabilization keep the antennas and solar panels pointing in the desired directions.
