On April 29 and 30, 2022, the Jiuquan Satellite Launch Center on the mainland and the Yellow Sea sea respectively sent seven satellites into the predetermined orbit with two rockets of different models. Beijing Aerospace Yixing Technology Co., Ltd. (hereinafter referred to as "Aerospace Yixing") provides measurement and control services for the four-dimensional Gaojing-1 01 and 02 satellites carried by the Long March 2 C carrier rocket and the "Jilin No. 1" series of five satellites carried by the Long March 11 solid carrier rocket.
The success of the high-intensity and intensive launch mission twice a day also means a great leap forward in the mainland's space launch capabilities and commercial measurement and control capabilities.
Aerospace Star Measurement and Control Center
Founded in 2016, Aerospace Drive Star is a leading global aerospace infrastructure construction and operation service provider in China. It mainly provides customers with comprehensive services for commercial satellite on-orbit operation and maintenance, including launch measurement and control services, satellite measurement and operation control services, remote sensing satellite calibration services, satellite collision early warning services, satellite orbit control services, etc. Provide one-stop solutions for global commercial satellites for low-cost, highly reliable and more convenient satellite in-orbit integrated management and aerospace data applications.
Commercial satellite measurement and control and commercial rockets, commercial satellites and other market segments began to develop synchronously, Aerospace Star CEO Zhao Lei said, "2016 is the first year of commercial satellite measurement and control. In December of that year, China's first science popularization satellite for middle school students, the Bayi Youth Xing satellite, successfully entered orbit with the Long March 2 Ding carrier rocket. The on-orbit measurement and control of the 'Bayi Youth Line' satellite is the first time that the mainland has entrusted third-party commercial measurement and control, marking the official opening of the mainland's commercial measurement and control market. ”
Due to the increase in commercial satellites and the beginning of their application scenarios, the commercial satellite measurement and control market is also continuing to expand, there are data show that by 2025, the mainland will launch more than 3,000 commercial satellites, satellite measurement and control This market size is expected to exceed 50 billion yuan.
Satellite measurement and control referred to as TT&C, mainly includes three parts: tracking, telemetry and remote control, of which tracking technology involves tracking, speed measurement, ranging, etc., to achieve continuous monitoring of satellites and data communication.
Aerospace Has created a complete product matrix, including multi-functional baseband, on-board communication machine, multi-functional ground station, portable station, etc. It also developed its own measurement and operation control software, constellation management software, task planning software, etc. These software and hardware systems, on the one hand, meet the needs of aerospace vehicles at a lower cost, on the other hand, they have also formed a customized software sales system.

Zhao Lei said: "In the measurement and control services of low-orbit commercial satellites, the ground station antenna is a more critical part. The aerospace station adopts a 4.5-meter aperture antenna as the satellite measurement and control main station, a 7.5-meter and 12-meter aperture antenna as the satellite data receiving main station, and a small-caliber portable station as a supplement, which realizes flexible deployment and meets the various emergency needs of users."
At present, there are not many commercial satellite measurement and control service companies in the mainland, mainly including aerospace driving satellites, Guokehua Road, Huanyu satellites, etc., while there are even fewer companies that can continuously provide stable measurement and control services. The survey shows that in terms of market share, number of ground stations, research and development capabilities, aerospace vehicles are relatively leading. The main advantages of the space drive come from the following three aspects:
1. Aerospace Driving Star has a professional technical team and a systematic technical system. The core members are from the core units of the original space system, and master the core technologies of software, hardware and services related to satellite measurement and control. At present, Aerospace Star has more than 200 employees, of which more than 70% are technical research and development personnel, and the core personnel have senior titles or above.
2. Aerospace Star has a global network of self-built ground stations. It has built the most complete commercial satellite measurement and control network in the mainland, including more than 50 sets of self-built ground stations and dozens of cooperative ground stations, covering most parts of Europe, Asia, South America, Africa, Oceania and so on. It can provide early stage tasks in any area, 100% coverage of SSO orbital laps, and data reception capacity of more than 20 times per day.
3. The space driving star has served 136 stars/arrows in total, and has rich experience in aerospace engineering missions. After more than 100 missions, aerospace vehicles have accumulated rich experience in orbit control, precision orbit determination, multi-satellite multi-task parallel control, rapid response, etc., and the current measurement and operation control system has the ability to serve more than 1,000 satellites.
