Available Information



The availability of global navigation satellite systems (GNSS) and other space-based systems is creating an unprecedented opportunity, bringing benefits in the areas of emergency management, marine and land monitoring or fleet control to name a few. Due to this availability, the development of integrated applications is an area in rapid expansion. To address a wide array of GNSS applications for socioeconomic benefits and to focus on initiating pilot projects and strengthening the networking of GNSS-related institutions in the region, a five-day Workshop will be held in Ulaanbaatar, Mongolia, from 13 to 17 April 2020. For details, see Information Note

The Workshop programme will include plenary sessions described below and also sufficient time for discussions among participants to identify the priority areas, where pilot projects should be launched and examine possible partnerships that could be established. Cooperative efforts and international partnerships for capacity-building, training and research will be discussed.

The main objective of the Workshop is to focus on the importance and need of cooperation to apply GNSS solutions through the exchange of information and the scaling up of capacities among countries in the region.


Thematic Sessions

Session 1: Current and planned GNSS and satellite-based augmentation systems

  • Programme updates on GNSS and satellite-based augmentation systems: GLObal NAvigation Satellite System (GLONASS) and System of Differential Correction and Monitoring (SDCM), Global Positioning System (GPS) and Wide-Area Augmentation System (WAAS), European Satellite Navigation System (GALILEO) and the European Geostationary Navigation Overlay Service (EGNOS), BeiDou Navigation Satellite System (BDS), Indian Regional Navigation System (NAVIC) and GPS Aided Geo-Augmented Navigation (GAGAN), Quasi-Zenith Satellite System (QZSS).

Session 2: GNSS-based applications focusing on, but not limited to

  • Advances and performance benefits due to multi-sensor integration of GNSS applications in surveying and geodesy;
  • The use of GNSS for aviation, including integration of satellite navigation technology into air traffic management and airport surface navigation and guidance;
  • The use of navigation and timing systems for road, rail, and engineering applications, including vehicle guidance, geographic information system (GIS) mapping, and precision farming;
  • Navigation systems operation in marine environment, including waterway navigation, harbour entrance/approach, marine archaeology, fishing, and recreation;
  • Commercial applications of GNSS;
  • The use of GNSS signals for navigation and positioning of in-orbit space operations, particularly from low-Earth orbit to cis-Lunar.

Session 3: GNSS spectrum protection and interference detection and mitigation

  • ICG activities and its role in spectrum protection and interference detection and mitigation.

Session 4: GNSS and space/atmospheric weather monitoring

  • Atmospheric monitoring (troposphere) to improve numerical weather predictions;
  • Space weather monitoring (ionosphere) for space situation awareness

Session 5: GNSS reference frames/systems and reference station networks

  • Programme updates on regional and national reference frames/systems and perspectives for a regional cooperative mechanism;
  • International GNSS Service (IGS) and other initiatives, CORS network and multi-GNSS environment.

Session 6: Capacity building, training and education in the field of GNSS

  • GNSS education opportunities at different levels/needs;
  • The strengthening of a specialized master's programmes for long-term professional education and support to PhD training and networking in GNSS;
  • GNSS education tools/open source software related to GNSS.

Objectives and Expected Outcomes

The specific objectives of the workshop will be:

  1. to introduce GNSS and its applications to transport and communications, aviation, surveying, mapping and Earth science, management of natural resources, the environment and disasters, precision agriculture; high precision mobile application, as well as space weather effects on GNSS and dual-frequency receivers;
  2. to promote greater exchange of actual experiences with specific applications;
  3. to focus on appropriate GNSS applications projects at national and/or regional levels;
  4. to encourage greater cooperation in developing partnerships and GNSS networks, in the framework of the regional reference frames; and
  5. to define recommendations and findings to be forwarded as a contribution to the Office for Outer Space Affairs, ICG and a "Space2030" agenda, particularly, in forging partnerships to strengthen and deliver capacity-building on satellite navigation science and technology.

The expected outcomes of the workshop are:

  1. recommendations and findings on discussed topics to be adopted by the workshop participants;
  2. preliminary agreement of cooperation between countries in the region and CORS networks;
  3. action plan addressing identified issues/concerns.

Additionally, building on past coordination and capacity-building activities, the current workshop could consider, inter alia, the following issues for recommendations:

  • Better define pilot projects to strengthen collaboration at regional level;
  • The creation of regional networks of GNSS-related institutions, including the regional centres for space science and technology education affiliated to the United Nations;
  • Propose actions to progress in the establishment of common and uniform continental reference coordinates frames and systems;
  • Promote actions for the development of modernized national horizontal reference systems, including deformation models and vertical datums based on accurate local geoid models;
  • Propose means to build capacity in regional geodetic project with a focus on GNSS data processing and the use of open geodetic software in cooperation with entities such as the International Federation of Surveyors (FIG) and the International Association of Geodesy (IAG).
