The second anniversary optimization and upgrade of Beidou network network

In order to further improve the service performance of the Global Satellite Navigation System of Beidou and ensure that the navigation services are more secure, stable, and reliable, the Xi'an Satellite Surveying and Control Center has participated in the implementation of satellite -oriented software optimization and upgrading. On the second anniversary of the opening of the service of the Beidou III system, phased software optimization has been successfully completed in the orbit verification work. After evaluation, various indicators meet the requirements.

Popularly speaking, the optimization and upgrading of satellites on track software is similar to upgrading the smartphone operating system with the help of OTA means, but it is different, during the process of the Satellite's rail software upgrade, ground scientific and technological personnel should ensure that the entire system is continuously operated and stable, so as to use it to operate continuously and stabilize, so as to use it to run continuously and stable, so as to use it to run continuously and stable, so as to use it to operate continuously and stabilize. The service performance is steady. It is understood that the software optimization and upgrade work involves most of the systems of the entire system, with a total of more than a hundred configuration items. The total task is large, the software optimization involves the complicated technical status, the upgrade test verification has high time limit, and it is difficult to implement.

To this end, the center of scientific and technological personnel of the center has developed a special software for data review and comparison, and achieved remote control instruction operations, greatly improving the efficiency of work. At the same time, they have strengthened their internal work relationships, strengthened communication and coordination, strictly implemented the dual -post order review system, operated every day based on task progress, and communicated closely with the operation control system and the development unit. The "one -star one, one table, one table" and a number of emergency plans are formulated to provide a strong guarantee for the continuous and stable operation of the Beidou global navigation system during the upgrade and optimization of the rail software.

Entering the center of the center of the Beidou Navigation Satellite Management Hall, Ding Mengyu, the project team leader, is organizing scientific and technological personnel to study the next stage of the operation rules. According to reports, in the second anniversary of the operation of the Beidou Global Navigation System, they have formed a professional management and control team of Beidou systems to continuously summarize satellite management experience, standardize system systems, and optimize organizational management models. Implementation rules and special system documents, so that the operation is standardized, the actions are based, and the laws and regulations are made.

"The constellation network is not done overnight. Each Beidou satellite is a precious space asset. The mission of maintaining the stable operation of the entire system is equally difficult and long. In the future operation management process, we will continue to optimize the organizational model, innovative technical means, and we will continue to optimize the organizational model. Make sure that the service is reliable and let everyone use it. "Ding Mengyu said.

In the future, the center will continue to strictly organize the principles of obedience to quality, strictly organize, accurately manipulate, continue to promote project implementation, and make every effort to ensure the successful completion of software optimization and upgrade work, and provide strong support for the continuous stable operation of the Beidou global navigation system.
