"The PrimeSat Controller is a complete and automatic controller for Satellite Communication Stations. When there is the need to communicate by voice or data through a circular or elliptical, low or high orbit satellite, it is absolutely essential to have a continuous adjustment of the antennas and station operating frequencies, in order to guarantee the best alignment and RF signal, as also the correct frequency compensation due to Doppler effect."
