Background

The maritime mobile communication generally refers to the communication between a land base station and a ship or a warship, the electric wave propagation path of the maritime mobile communication is almost the sea surface, and the propagation condition is superior to that of the land. When there are no islands or other obstacles in the propagation path, the propagation loss can be analyzed according to the propagation theory of a smooth spherical surface earth. The measured field strength of the marine propagation is given as a function of distance. A large number of actual measurement results show that: when a ship is underway, if there is no obstacle in the propagation path and the nearby water area, the signal electric field intensity does not change much, its instantaneous value changes by about 3dB, and the median change of one minute is only about 1 dB. In the past, the VHF frequency modulation and the HF single-sideband system are mainly used for marine communication and aeronautical communication. The radio wave propagation in the VHF band is generally limited to the line-of-sight range, and the radio wave propagation is greatly affected by the ionosphere and the fading phenomenon is very serious although the communication range in the HF band is not limited to the line-of-sight range. In addition, users in the HF band are crowded, interference is large, and it is difficult to increase communication capacity. To address this issue, satellite relays may be utilized to implement both maritime and airborne communications.

The marine mobile communication device mostly utilizes a satellite receiver to receive and propagate signals, and a satellite receiving system comprises: a set of complete satellite ground receiving station is composed of a parabolic antenna, a feed source, a high-frequency head and a satellite receiver, the parabolic antenna is used for reflecting and converging satellite signal energy from the air into one point, and the function of real-time positioning is achieved.
