Multi-beam high-flux satellite forward link power band balancing system

Abstract

The invention discloses a multi-beam high-flux satellite forward link power band balancing system, and relates to the technical field of satellite communication. The multi-beam high-flux satellite forward link power band balancing system comprises a gateway station main station carrier wave monitoring system, a satellite monitoring system and a gateway station small station carrier wave monitoring system. The gateway station main station carrier wave monitoring system is connected to the satellite monitoring system; the satellite monitoring system is used for realizing satellite telemetry parameter monitoring, and the satellite monitoring system is connected to the gateway station small station carrier wave monitoring system; the gateway station small station carrier wave monitoring system is used for realizing reverse carrier wave real-time polling monitoring, and the gateway station small station carrier wave monitoring system is connected to the gateway station main station carrier wave monitoring system; the multi-beam high-flux satellite forward link power band balancing system has a normal monitoring cycle state and an abnormal monitoring cycle state. The method has the beneficial effects that the system stability of the whole forward link is greatly improved, and monitoring circulation is performed in each link in the link.

Description

technical field [0001] The invention relates to the technical field of satellite communication, more specifically, the invention relates to a multi-beam high-throughput satellite forward link power band balance system. Background technique [0002] High Throughput Satellites improve satellite capacity through key technologies such as multi-spot beams, frequency multiplexing, and high beam gain, and can provide several times or even dozens of times higher capacity than conventional communication satellites. Compared with the capacity of traditional communication satellites less than 10 gigabits per second (Gbit / s), the capacity of HTS can reach tens of gigabits per second to hundreds of gigabits per second. [0003] The multi-beam satellite communication system adopts cellular mobile communication and uses several high-gain spot beams to cover a larger area. Due to the different areas covered by the spot beams, the service requirements and channel conditions in the coverage a...

Problems solved by technology

[0007] The existing mature commercial multi-beam satellite systems are mainly based on fixed distribution methods, but once the distribution results are confirmed, the fixed distribution method keeps the power fixed, and its power bandwidth distribution does not form a closed-loop adaptive adjustment mechanism, which is difficult to apply in various complex application scenarios and Maintain power bandwidth balance in the environment
