Description
Technical Field
[0001] The present invention relates to the technical field of satellite communication terminals, and in particular to a portable integrated satellite communication terminal. Background Art
[0002] Satellite communication user stations are an important part of satellite communication systems. Among them, portable satellite communication user stations (including antennas, RF front ends and satellite communication terminals) have become the most common form of user stations due to their small size, low cost and ease of use. They are widely used in public security fire fighting, emergency communications, resource exploration and other fields.
[0003] Traditional satellite communication terminals do not include equipment such as antennas and RF front-ends. In the field of emergency communications, they are generally used in conjunction with portable satellite antennas. Portable satellite antennas generally take the form of parabolic antennas, which work with BUC and LNB to form the antenna feed equipment of a portable user station. This type of parabolic antenna generally has multiple panels on the antenna surface. When in use, they need to be spliced and then installed with components such as brackets, feeds, BUC (Block Up-Converter, up-conversion power amplifier and LNB (Low Noise Block, high-frequency head), and finally use cables to connect the antenna and satellite communication terminal before use. In addition, due to the irregular shapes of the various accessories of the antenna, it is also very inconvenient to store them. This type of equipment often requires one or two suitcases for storage and transportation. Summary of the invention

After the terminal receives the user IP data, it is encoded and modulated by the digital baseband unit 202 to form an intermediate frequency signal, and the transceiver is used to convert the frequency, filter and amplify it, and finally radiate it toward the satellite through the antenna. Full-duplex communication technology is an existing technical means. The present invention applies the existing full-duplex communication technology and does not improve the full-duplex communication technology.
