Satellite data acquisition system and its key technologies
The satellite data acquisition system utilizes aerospace telemetry, remote control, remote monitoring and other technologies to monitor the apogee of spacecraft, automatically collect data according to requirements, transmit it to the data center for processing, and send it to the user's application system for use.
The technical characteristics of the satellite data acquisition system are: it can automatically extract the collected data; Low data rate; Time division data collection;
● Wide coverage area; Can work in the field; Unattended.
The advantages of satellite data acquisition systems are: high timeliness; Collecting data from a wide geographical area; Excellent economic efficiency; Strong authenticity.
The main components of a satellite data acquisition system include sensors, acquisition platforms, satellite acquisition channels, data receiving stations, network management, and central processing systems. The satellite data acquisition system is coordinated by space satellite channels, sensors, data acquisition platforms, user data receiving stations, and central management stations. Each user data collection platform group and receiving station form a subsystem, and the central management station centrally manages and coordinates the system's satellite channel allocation, data resource exchange, system operation, etc. The satellite channel is a channel for meteorological satellites, resource satellites, or communication satellites.
The key technology of satellite data acquisition system is:
1. Development of specialized sensor technologies, such as sensors for monitoring the moisture content of surface combustibles in forest areas, soil moisture sensors, and sensors for measuring the composition of marine hydration.
2. Efficient energy technology, due to poor power conditions in the location of the data platform, requires the development of efficient solar power sources, high-energy batteries, etc.
3. Develop system network management and control technology to achieve automated monitoring of system resource sharing and information exchange status.
4. Development of an intelligent data acquisition platform with high reliability, low power consumption, and remote control program download.
5. Development of high stability and miniaturized frequency sources.
