Galilleo GNSS Service restored

Carlos des Dorides, executive director of the GSA made the following statement after restoration of GNSS services over the Galilleo satellite constellation.

“As members of the GNSS community, you are all undoubtedly aware of the recent technical incident that resulted in the temporary interruption of Galileo navigation and timing services.

The technical incident originated by an equipment malfunction in the Galileo ground infrastructure, affecting the calculation of time and orbit predictions, which are used to compute the navigation message. The technical incident affected different elements of the ground facilities.

The team is monitoring the quality of Galileo services to restore the Galileo timing and navigation services to their nominal levels. As soon as we gather all the technical elements and implement all necessary actions, we will provide more detailed information through our NAGU (Notice Advisory to Galileo Users) notifications to users.

All partners worked together to remedy the situation as soon as possible. We will set up an Independent Inquiry Board to identify the root causes of the incident. This will allow us to draw lessons for the management of a global operational system with several millions of users worldwide.

The Galileo system has grown stronger as a result of this experience, and we will continue to deliver Initial Services until full operational capability is declared. These challenging days have shown us how much you, the GNSS user community and stakeholders, rely on Galileo and how much you trust the Galileo system to deliver the services to support growth, business and sustainability. Europe and the world need a strong civil global satellite navigation system today more than ever.” http://www.gsa.europa.eu

Glonass protected against errors that hit Galileo

Russia’s Glonass satellite navigation system is protected against technical issues that earlier knocked down its European rival, Galileo, a spokesperson for Russia’s space corporation Roscosmos said recently.

“[The Glonass system] is certainly protected. In order to prevent such errors, rocket and space industry enterprises have a multiple-level checking systems for software. Besides, the ground-based control hub of the Glonass space system has automated control systems and reserve capacities,” the source said.

“Flight trials [of Glonass spacecraft] envisage simulation of emergency situations, and operating instructions contain measures for tackling them,” he added. https://tass.com

State Duma ratifies Russia- China agreement on national satellite system station

The Russian State Duma (lower chamber) has ratified an agreement between the Russian and the Chinese governments on cooperation in applying the GLONASS and the BeiDou global national satellite navigation systems, envisioning a mutual deployment of stations on their territories.

The agreement was signed in Beijing on November 7, 2018. According to the explanatory material, the agreement stipulates deployment of measurement station for the GLONASS and the BeiDou systems on the territories of China and Russia respectively to develop functional additional features of GLONASS and to create a global system of control and confirm the radio navigation zone characteristics of this system. https://tass.com
