On September 6th, the "Quancheng No. 1" Kuaizhou No. 1 A -Solid carrier rocket sent the micro -space low -orbit satellite navigation system S3/S4 test satellite into the scheduled track. What is the role of the test satellite? When will the network launch start? How will they serve people's lives in the future? New Yellow River reporters interviewed this.

"The main purpose of test satellites is to conduct a number of innovative key technologies of systems and satellites, interface protocols and operating timing between satellites, ground, and users, and the performance of the system to provide services. Realize the status to meet the expectations, and provide a basis for determining the status of the Star Place in the subsequent large -scale networking phase. "The relevant person in charge of the test satellite developer Shandong Future Navigation Technology Co., Ltd. introduced that in October this year, it was ready to launch the last group of test satellites in Yantai. Currently S5 The development of S6 satellite is progressing smoothly. It is conducting various tests and testing before the factory is planned. The state is in good condition and will be shipped to the launch site in the near future. The S5 and S6 satellites will operate with the S3 and S4 satellites launched this time, and 4 stars will complete all track tests and demonstration tasks. Small network launching will begin early next year, and will begin to enter the dense launch period in the middle of next year. It is planned to complete all more than 100 satellite launch by 2025.

In recent years, Jinan has been deploying remote sensing satellites. Satellite remote sensing is an important type of satellite application direction. It is mainly through satellites, according to the theory of electromagnetic waves, using various sensing instruments Collect treatment and extract people's care features, such as optical or radar images, atmospheric temperature, high ocean waves. The scope of satellite remote sensing is very wide.

Satellite navigation is another important satellite application direction that has developed in the past 30 years. The current mainstream technology is electromagnetic wave signals with accurate time and frequency information through satellites. The user calculates its own position and time by receiving these signals. The addition of low -orbit navigation satellites can greatly enhance the user feelings of traditional satellite navigation.

What can Beidou low -orbit satellite navigation enhancement system do in the future? According to reports, the Beidou low -orbital navigation enhancement system can provide global users with a high -precision navigation positioning service, high -precision timing service less than 1 nanosecond, and intact service that meets precision requirements such as aviation. These services have extensive demand in the fields of autonomous driving, precision agriculture, special logistics management, mobile communication, power network, aerospace and other fields.

Beidou low -orbital satellite navigation enhancement system plans to conduct trial operation at the end of 2024, select several typical application scenarios to conduct service performance verification and evaluation, and open services to global users in 2025.
