The Department of Geophysics, Faculty of Mathematics and Natural Sciences (MIPA), Hasanuddin University (UNHAS), organized an International Workshop titled “Introduction to GNSS and Its Application” on Tuesday 2 December 2025. The event featured Lujia Feng, an Assistant Professor from the Earth Observatory of Singapore, Nanyang Technological University (EOS–NTU), as the main speaker, and was moderated by Muhammad Taufiq Rafie, an Assistant Professor from the Department of Geophysics.

The workshop provided an in-depth introduction to the Global Navigation Satellite System (GNSS), covering fundamental concepts, types of data generated, instrumentation, and examples of its current applications in Earth science. The program consisted of two 45-minute sessions, focusing on the basics of GNSS and its applications in monitoring Earth’s surface dynamics.

In her presentation, Lujia Feng emphasized that GNSS data play a crucial role in precisely monitoring tectonic plate motion through measurements of relative positional changes with respect to satellites. Such data also serve as an essential basis for studying potential earthquake sources and supporting geological disaster mitigation.

The workshop was attended by 76 participants, including undergraduate and graduate students, as well as alumni of the Department of Geophysics. Participant enthusiasm was evident from the number of questions raised, particularly regarding opportunities for GNSS research development in Indonesia and its application in geological hazard mitigation.

Through this activity, the Department of Geophysics aims to advance the fields of geodesy and geodynamics within the academic community while opening opportunities to enhance research capacity through collaboration with global institutions such as NTU Singapore.
