The invention discloses a ground station for implementing communication between a satellite and the ground. The problem that the original ground station has a large volume and low reliability is solved, the cost of the ground station is greatly reduced, and automatic tracking and one-station-multi-satellite signal transceiving. The ground station disclosed by the invention is composed of an antenna subsystem and a signal processing system. The antenna subsystem is composed of two groups of UHF antenna arrays and two groups of VHF antenna arrays, wherein group of UHF and VHF is respectively composed of a circularly polarized antenna which is synthesized by two mutually orthogonal yagi antennas. The signal processing system is composed of an uplink amplifying circuit, a downlink filtering circuit and a downlink low noise amplifier, wherein the uplink amplifying circuit completes two-stage amplification of an usrp output signal, the downlink filtering circuit adopts a general graph filterto complete the bandpass filtering of 437.645 MHz, and the downlink low noise amplifier completes low noise amplification of a downlink signal.
