At 1 o'clock on July 11, Galileo's navigation system service was suddenly interrupted, and all ground signals were lost. Until 8 o'clock, there was no sign of resuming service. Beginning at 1:00 on July 11, users will experience service interruption of the "Galileo" satellite navigation system, and services will be unavailable. The specific recovery time is to be determined. According to the "Monitoring and Evaluation Center" report, Galileo's system was abnormal for 3 hours at 14-15 and 17 o'clock UTC on July 10, 2019 (22-23 on July 10 and 11:00 on July 11, Beijing time). The broadcast ephemeris of its satellite navigation signals has not been updated.
"Galileo" positioning system is a satellite positioning system under construction. The system is built by the European Union through the European Space Agency and the European Navigation Satellite System Administration. It is one of the four global positioning systems, and its purpose is to build Europe's own satellites. Navigation system, get rid of the dependence on the US "Global Positioning System" (GPS).
According to iGMAS data, there was a service outage in this "Galileo" and the broadcast ephemeris of its satellite navigation signals was not updated.
It is reported that in the following period, the situation continued to deteriorate, and the 24 satellites of the Galileo navigation system continued to lose contact and disconnection.
On August 21, 2011, the first satellite of Galileo was launched. The system plans to launch 30 satellites, which will be completed before 2020. In 2019, the "Galileo" system will begin to be fully operational. There are currently 24 satellites in orbit. It is estimated that all 30 satellites will be deployed by 2020. The system was originally planned to have all navigation functions in 2019, but it collapsed at a critical moment.
Some analysts pointed out that at the critical moment when the Galileo navigation system has all the navigation functions, a "collapse" accident will severely dampen the market's confidence in this emerging navigation system, cause concern about its system reliability, and promote its future promotion and The application prospect has a serious impact.
China's Beidou Navigation also released a message on July 12. Sources said that data from the Xi'an Satellite Measurement and Control Center showed that the 34 satellites of the Beidou Navigation System operating in orbit are stable and in good condition, and provide high-precision navigation services normally.
Galileo navigation and Beidou navigation are still quite related. In the early days, due to the blankness of China ’s satellite navigation system technology, it invested 230 million euros to participate in the European Union ’s Galileo navigation system development plan. To unequal treatment. In desperation, China withdrew from the Galileo navigation system development plan and set about developing its own Beidou navigation system. The Galileo navigation system has been intermittent, and the networking progress has been slow due to the financial problems of various countries. Although China's research and development experience in the navigation field was almost blank at that time, after hard work, it later took the lead and launched the satellite five years before Galileo launched.
Since its establishment in December 2003, the party branch in the navigation field has led all party members and staff to hold the national door key with high-quality satellite products, and has completed the Beidou navigation test satellite, Beidou 2 satellite, and Beidou 3 test stars. Development and launch missions of 14 satellites and 37 satellites. According to the plan, in 2020, a world-class satellite navigation system will be built to provide better services; in 2035, a more ubiquitous, more integrated, and more intelligent integrated positioning and navigation timing system with Beidou as the core will be completed.
