The satellite platform usually consists of eight subsystems including structure, thermal control, attitude and orbit control, propulsion, power supply and distribution, measurement and control, integrated electronics, and data transmission.<\/p>\n
1. Structure subsystem<\/p>\n
The satellite structure subsystem is the physical foundation of the satellite. Its core is to provide safe, reliable, accurate and stable support, protection and configuration guarantee for all satellite equipment at the minimum weight cost under extremely harsh mechanical and space environmental conditions. Its design, analysis and verification are crucial and highly technical links in satellite engineering.<\/p>\n
The design of structural subsystems requires knowledge in engineering mechanics, mechanical engineering, mechanical design, manufacturing and automation, materials science and engineering, aircraft manufacturing engineering, etc.<\/p>\n
2. Thermal control subsystem<\/p>\n
The satellite thermal control subsystem is the “temperature guardian” that ensures the survival and normal operation of satellites in the harsh space environment. It uses a combination of passive (coatings, multi-layer insulation materials, heat pipes, etc.) and active (heaters, fluid loops, etc.) technical means to precisely manage the flow of heat inside the satellite to maintain the temperature at a safe and appropriate level. Its design is a very challenging and crucial task in spacecraft engineering, which is directly related to the success or failure and life of the satellite mission.<\/p>\n
The design of the thermal control subsystem requires professional support from energy power, power engineering and engineering thermophysics, materials science and engineering.<\/p>\n
3. Attitude and orbit control subsystem<\/p>\n
The attitude and orbit control subsystem is one of the core subsystems of the satellite and is responsible for the attitude stability, orbit maintenance and maneuver control of the satellite in space. Its design needs to tightly couple load requirements and space environment constraints. Future trends focus on higher precision (sub-arcsecond level measurements), greater autonomy (AI decision-making), and deep modularity (common platforms reduce costs).<\/p>\n
The design of the attitude and orbit control subsystem generally requires majors in aerospace, aerospace science and technology, control science and engineering, and astronomy.<\/p>\n
4. Promotion subsystem<\/p>\n
The satellite propulsion subsystem is an indispensable “engine” and “steering wheel” for satellite operation in orbit and completion of missions. It is mainly responsible for providing the required thrust and torque for the satellite to achieve orbit control, attitude control, initial attitude acquisition and other functions. Its performance, reliability and lifespan directly determine the mission capability and on-orbit lifespan of the satellite. With the advancement of technology, electric propulsion and green propulsion are becoming the mainstream development directions of future satellite propulsion.<\/p>\n
The design of propulsion subsystems generally requires majors in aerospace, aerospace science and technology, etc.<\/p>\n
5. Power supply and distribution subsystem<\/p>\n
The satellite power supply and distribution subsystem is the “heart” and “blood circulation system” of the satellite. Its core task is to provide continuous, stable, reliable and required power for all instruments and equipment (payloads and platforms) of the entire satellite. It starts from capturing and converting raw energy (mainly solar energy), through efficient storage, intelligent regulation, and safe distribution, and finally provides the “blood”-electric energy that every “organ” on the satellite depends on for survival.<\/p>\n
The design of power supply and distribution subsystems requires knowledge reserves in electrical engineering, electronic information, automation, electronic science and technology, and power technology.<\/p>\n
6. Measurement and control subsystem<\/p>\n
The satellite measurement and control subsystem is responsible for establishing a two-way data link between the satellite and the ground control center. It is the only bridge connecting the satellites in the sky and the ground personnel to ensure the monitoring, control and management of the satellites. Without an efficient and reliable measurement and control system, no satellite mission can be successfully implemented.<\/p>\n
The design of the measurement and control subsystem requires majors in electronic information, information and communication engineering, and communications.<\/p>\n
7. Comprehensive electronic subsystem<\/p>\n
The satellite integrated electronic subsystem is the “nerve center” of the satellite. It replaces traditional distributed electronic equipment through high integration and intelligent management to achieve unified scheduling of satellite resources and task coordination. The satellite integrated electronic subsystem is undergoing a transition from “functional integration” to “intelligent core”.<\/p>\n
The design of integrated electronic subsystems requires professional knowledge in electronic information, computer science and technology, electronic science and technology, and software engineering.<\/p>\n
8. Digital transmission subsystem<\/p>\n
The satellite data transmission subsystem is the core hub for transmitting satellite payload data to the ground. It is responsible for data collection, processing, storage and high-speed transmission tasks. The satellite data transmission subsystem has developed from a single data transmission to a comprehensive platform integrating intelligent processing, anti-interference transmission, and multi-satellite network collaboration. Its technological evolution closely follows the needs of high resolution, real-time performance, and multi-load adaptation. In the future, with the integration of inter-satellite links, artificial intelligence compression and other technologies, the data transmission system will further make breakthroughs in the direction of “high-speed, intelligent, and adaptive”.<\/p>\n
The majors required for the design of digital transmission subsystems are electronic information, electronic science and technology, information and communication engineering, communications, etc.<\/p>\n","protected":false},"excerpt":{"rendered":"
