Abstract

The invention discloses an intelligent core system with measurement and control functions and a center computer function and relates to the field of rapid spacecraft platform designing. The intelligent core system solves the problems that in microsatellite integrated electronic system, a measurement and control transponder and a center computer are large in size, heavy in weight and low in functional density. The intelligent core system with the measurement and control functions and the center computer function comprises two data transmission and processing systems, an interface module and a power supply and distribution module. Each data transmission and processing system comprises an RF channel module and a data management module. The RF channel modules are used for receiving RF signals and processing the received RF signals to generate a baseband data flow, so that conversion between the RF signals and baseband data is achieved. The data management modules are used for remotely controlling telemetric terminals and computers according to the RF signals. The RF channel modules and the data management modules achieve data interaction through the interface module. The power supply and distribution module is used for transmitting power-on / off instructions to the RF channel modules and the data management modules. The intelligent core system is applicable to communication of microsatellite systems.

Description

technical field [0001] The invention relates to the field of rapid spacecraft platform design. Background technique [0002] In order to meet the needs of future space technology development, and taking into account the complex and changeable international environment, my country has carried out research on the concept and connotation of small satellites, and gradually established a principle of "fast", "smart" and "cheap". The road to the development of small satellites with Chinese characteristics. The integrated electronic system is responsible for completing satellite information collection, intra-satellite / satellite-ground interaction, processing and application, and is the overall electrical sub-system of the satellite. In the integrated electronic system of small satellites, other stand-alone components can adopt flexible designs, but the measurement and control transponder and central computer are the core of any integrated electronic system, and they are the indispe...
