From March 19th to March 23rd, 2018, the United Nations Workshop on the Applications of Global Navigation Satellite System was held in Cordoba, Argentina’s second largest city. The workshop was co-sponsored by the United Nations Office for Outer Space Affairs (UNOOSA) and the Argentine Government, and organized by the Argentina Space Agency (CONAE). More than 80 officials, experts and representatives from 4 international organizations, 24 countries and regions including the United States, Russia, China, the European Union, Japan, Brazil and Paraguay attended the meeting.

This is the first time for the UNOOSA held the workshop in South American countries. The satellite navigation authorities from the United States, Russia, China and Europe introduced the latest developments and applications of 4 GNSS Systems and their augmentations. Representatives from Argentina, Paraguay, Latvia, Croatia, Brazil, Mexico, and Ecuador exchanged views on the application requirements and status, problems, and technological development of the satellite navigation applications in land surveying and mapping, disaster prediction, civil aviation air control, infrastructure construction, resource protection, and scientific research. During the exchange of reports, some representatives from South American countries and Nordic countries expressed their keen attention to join the BDS.  They proposed to use multi-system solutions including BDS in the system upgrade and application solution update of CORS. 


The Chinese delegation had five reports for discussion and exchange. The representative of China Satellite Navigation Office (CSNO) introduced the BDS development status and its ground-based and satellite-based augmentation systems. The BDS solutions in transportation, public safety, civil disaster reduction, and precision agriculture were also discussed. Representatives of the China Transport Telecommunications & Information Center and China North Industries Group Corp Ltd exchanged and discussed the BDS application solutions of in the field of transportation, ground-based argumentation systems, and high-precision location services. During the meeting, the UNOOSA also organized related experts to discuss the themes of “GNSS spectrum protection and interference detection and mitigation” and “GNSS and space/atmospheric weather monitoring”, covering satellite navigation principles, characteristics and interference analysis of the GNSS signals, the introduction of ITU, radio spectrum management, GNSS interference cheating events and the current policies and measures introduced by various countries. It aimed at advocating countries to pay attention to satellite navigation frequency protection and provide a safe and reliable frequency environment for GNSS applications. The National Time Service Center of the Chinese Academy of Sciences represented China introduced China’s progress and efforts in spectrum protection of satellite navigation. The workshop is an important part of the UN space application program. It aims to help developing countries to promote cooperation and exchanges in GNSS applications and to serve the sustainable development of economy and society. The content covers the construction of satellite navigation systems, application promotion, education and training, etc. It would be reported to the International Commission on Global Navigation Satellite Systems (ICG). In 2001, the United States hosted the first workshop. So far it has been held 20 times and played an important role in promoting the application of satellite navigation and has a greater influence in developing countries. The CSNO has participated in the application seminar for several times and played an active role in promoting the BDS internationalization.
