Tai Po Earth Station was completed and put into service in June 2003. The earth station integrates satellite measurement and control, user network monitoring and management, and carrier uplink and downlink services. Equipped with double-guarantee power supply system and perfect fire safety facilities, as well as meteorological monitoring equipment. The design of the main building and antenna of the earth station fully considers the influence of typhoon in summer. All antennas meet the design standard of strong wind, and can resist the strong wind with a speed of 300 kilometers per hour. There is no need to shelter from the wind during the typhoon, which ensures the all-weather monitoring of the Asian satellite series.
Asia Tai Po Earth Station is a comprehensive satellite ground facility with excellent performance in Asia, which can measure and control up to 7 satellites at the same time. Equipped with advanced user network monitoring equipment, various satellite communication radio and television equipment and supporting software systems, it can provide users with more comprehensive and perfect user network management services and other value-added services. The Asian Satellite Control Center (SCC) is located in Tai Po Satellite Earth Station, which is mainly responsible for the real-time 7X24 uninterrupted telemetry, remote control and tracking of the Asian satellite series, monitoring the satellite's orbital position accuracy, flight attitude and the working state of on-board equipment, so as to command and control the operation of each subsystem and adjust the satellite's orbital position and attitude.
The satellite control center also undertakes the responsibilities of user communication network monitoring, interference analysis and investigation, and carrier operation management. At the same time, monitor the operation of nearby satellites, and keep close contact with users and other satellite companies to prevent interference.
The satellite control center is connected with the satellite control system of the Stanley Earth Station in Asia through a special optical cable, so that the Stanley Earth Station can be used as a complete backup facility of the Tai Po Earth Station, and the whole monitoring system can run with high reliability. This kind of backup guarantee is second to none in Asia.
In order to improve the service quality, Asia transmitted the business monitoring signal of the satellite control center to the Beijing office in real time through the private network line, forming a network monitoring system for local users, which greatly enhanced Asia's ability to provide localized services for China users. Asia Stanley Earth Station is located in Stanley Peninsula at the southernmost tip of Hong Kong Island, adjacent to the communication hub PCCW. The Stanley ground station consists of a measurement and control room, five C-band antennas and two Ku-band antennas, which are mutually backup with the Asian satellite Tai Po ground station.
C-band antennas are used to track and control Asia-2, Asia-3 and Asia-4 satellites. Usually, an automatic tracking antenna of 1 1 m and a fixed antenna of 5 m are used for 3S satellites in Asia, tracking antennas of 9 m and 6 m are used for II satellites in Asia, and another automatic tracking antenna of 1 1 m is used for IV satellites in Asia. Except for the 5-meter antenna, the other four antennas can be easily aimed at any of the three satellites. Similarly, in the configuration of RF equipment, the redundancy and flexibility of simultaneous measurement and control of three satellites are fully considered. Two sets of 6. 1m Ku band step tracking antennas are used to provide technical support and services for Ku band users of AsiaSat-2, AsiaSat-3S and AsiaSat-4.
