The Regional Centre for Mapping of Resources for Development (RCMRD) invites the related international communities to register for the African Geodetic Reference Frame (AFREF) and Global Navigation Satellite Systems (GNSS) Data Processing workshop. The workshop, which is slated for October 4 to 8, 2021, aims to provide a forum for land surveyors, geodesists, engineers, earth research scientists and cartographers from African countries with experience in Global Navigation Satellite System (GNSS) technologies. In addition, the purpose of the course is to provide knowledge and skills on the establishment of real-time geodetic networks using real-time control points/monuments in the form of CORS using GNSS technologies to support various positioning applications. Furthermore, the workshop will focus on knowledge transfer and collaborations between participants to initiate new projects.
African Geodetic Reference Frame (AFREF) is a modern and uniform geodetic reference frame for Africa, fully consistent with the International Terrestrial Reference Frame (ITRF) and global coordinate systems to support national, regional and global applications in Africa, including civil aviation, regional infrastructural development, land administration and management, precision & commercial farming, weather forecast, and other earth science studies.
- Global Navigation Satellite System (GNSS) technologies and applications;
- GNSS augmentation systems and availability in Africa;
- AFREF concepts, applications and progress;
- Continuously Operating GNSS Reference Station (CORS) and Real-Time GNSS Geodetic Networks (RGTN) concepts and needs for implementation;
- Reference systems, AFREF, datum and coordinate systems;
- Practical field works on static GNSS surveys, RTK using Bass/Rover, RTK using CORS; and
- Practical GNSS data post-processing and reporting using open data sources.
For applications and more information, kindly contact Racheal Umazi.
AFREF comprises a network of Continuously Operating Reference Stations (CORS) using Global Navigation Satellite Systems (GNSS) technologies. AFREF data and products are freely available and are used in various positioning applications with positioning accuracy from sub-meter to millimetre levels. Furthermore, AFREF is endorsed for implementation and supported by the International Association of Geodesy (IAG), International Global Navigation Satellite System Service (IGS), Federation of International Surveyors (FIG), United Nations Office of Outer Space Affairs (UNOOSA) and the United Nations committee of expert on Global Geospatial Information Management (UN-GGIM).
