(Beidou Government Website) On May 8th, 2015, under the witness of China President Xi Jinping and Russian federation President Vladimir Putin, on behalf of two countries, China Satellite Navigation System Committee Chairman Wang Li and Russian Federal Space Agency Chief Igor Komarov signed the “China’s Beidou system and Russian Glonass system Compatibility and Interoperability Cooperation Joint Statement”. It indicates that the navigation cooperation between China and Russia entered into a new stage. The two sides will continue to strengthen the compatibility and interoperability cooperation between Beidou and Glonass system, which promote the common development of two systems, so as to provide a better and more reliable satellite navigation service.
The compatibility and interoperability among satellite navigation systems is the world development trend. The compatibility mainly refers to multiple satellite navigation system use independently or together, without any unacceptable interference and damage for any single system; Interoperability mainly refers to the use of multiple satellite navigation systems and their services. Users can gain a better service from multiple systems than one. As the global satellite navigation systems develop into the era of multiple system coexist, compatibility and interoperability between systems can enable users enjoy more than one system services on single terminal without dramatically increase terminal devices’ technical complexity and cost. The compatibility and interoperability also contributes to maximum utilization of resources and services of global satellite navigation systems.
