Problems solved by technology

[0004] my country's large satellites (above 1,100 kg) use relay user data transmission terminal systems and relay satellites for data transmission and playback of overseas data. Although there are individual models of successful experience, it is the first time to design relay data transmission user terminals based on small satellites. , the main problems are: (1) how to optimize the system design of terminal products and carry out miniaturization under the limitation of the overall weight and power consumption of small satellites; The optimal and reasonable installation position of the relay user data transmission terminal system; (3) Under the limitation of the overall layout structure, how to carry out the system design of the small satellite relay data transmission user terminal, so that the user satellite and the relay satellite can be better Communication, so as to better meet the requirements of users

Embodiment Construction

[0027] The specific implementation manners of the present invention will be further introduced below in conjunction with the accompanying drawings.

[0028] like figure 1 As shown, the system of the present invention includes a transmitting channel, a system control module and a receiving channel. The transmitting channel includes a transmitting module, a power amplification module, and a transmitting antenna. The system control module includes a master control unit and a backup control unit. The receiving channel includes a receiving antenna, a filter module and trace receiver module. The system control module controls the dual-machine cold backup, and the receiving antenna and the transmitting antenna are shared.

[0029] like figure 2 As shown, the working flow chart of the relay data transmission user terminal system of the present invention, in the initial working state, the tracking and receiving module searches for the relay satellite signal received through the rece...

Abstract

The invention discloses a miniature relay data transmission user terminal system and a realization method thereof. The system includes a receiving channel, a transmission channel and a system control module, and at the same time, the invention also provides a realization method of the miniature relay data transmission user terminal system. With use of the invention, the overseas transmission problem of load data transmission required by the user is solved; the real-time data transmission capability of the satellite is improved; the arc of the load data transmission is increased; the requirement of the user is met to the maximum; and the executive ability of the satellite is improved.

Description

technical field [0001] The invention relates to a satellite relay data transmission user terminal system and an implementation method, and belongs to the technical field of data transmission of relay satellite systems abroad. Background technique [0002] In recent years, users have higher and higher requirements for the design of small satellite systems, as well as higher requirements for real-time payload data and observation arcs. At present, the only ground-to-ground data transmission of small satellites cannot meet the urgent needs of overseas data as soon as possible. Backhauling the requirements of the ground, so the use of relay data transmission user terminals in small satellites is a general trend. [0003] Outside the visible range of the ground data receiving station and within the visible range of the relay satellite, the small satellite relay user data transmission terminal system transmits a load data required by the user through the Ka relay antenna after mod...
