Swivel Antenna

Probably many people know that television satellites are in a geostationary orbit, which is a circular orbit located above the Earth’s equator (0 latitude), on which, an artificial satellite rotates around the planet with an angular velocity equal to the angular velocity of the Earth’s rotation around its axis, and constantly dwells on the same point on the earth’s surface. The satellites are located on the so-called polar arc (photo 1) at an altitude of approximately 36,900 km above sea level, the satellite’s altitude is not chosen randomly, but based on calculations of centrifugal force so that the satellite does not fall to the ground and does not fly into open space. So, a rotary antenna is a motorized antenna, designed in such a way that when moving it describes exactly the same arc as the one on which the satellites in space are located. Due to the Earth’s gravitational force and the centrifugal force that counteracts it, the satellites are stationary relative to the earth’s surface, so it’s enough to install a device (motor) to move the antenna along the given satellite Continue reading
