Claims

[Scope of utility model registration request]

A device for controlling the antenna of an artificial satellite for three-axis attitude control includes a plurality of reflectors arranged on each of the roll and pitch axes of the antenna, a circuit for receiving the output of the reflectors, and a laser beam directed to the reflectors. a laser angle detector equipped with a laser light source, an RF receiver having an antenna and a receiver capable of receiving beacon radio waves from a ground station, and dividing the output of the RF receiver into roll and pitch axis components; A meseri circuit that generates timing signals to switch signals and also outputs information on changes in the orbit environment, aging, safe operation, etc., and a command receiver that can rearrange the data in the memory circuit based on command signals from the ground station. a gap controller that controls the reflector output with a timing signal of the memory circuit output, an arithmetic circuit that converts the gap controller output into an antenna angle, a filter characteristic, and a D/A converter. An antenna control device for an artificial satellite, comprising: a control circuit; a power amplifier that amplifies a minute signal output from the control circuit; and an antenna drive mechanism that directs the antenna in a predetermined direction using the output of the power amplifier.
