[SOES' 25 YEARS WITH MACAO] China Releases Its First Independently Developed Real-Time Geomagnetic Field Model

Updated: December 16, 2024

The scientific team behind the “Macao Science 1” satellites has released China’s first real-time and four-dimensional geomagnetic field model.

The release represents significant progress in the scientific research and application of the “Macao Science 1” space exploration satellite project, and will play an important role in geoscience research and geomagnetic navigation.

The geomagnetic field model leverages high-precision data from the “Macao Science 1” satellites and is the first independently developed real-time geomagnetic field model in China. Its wide-ranging applications span geoscience research in Earth's interior, oceans and geospace, as well as practical uses in aerospace, marine navigation, resource exploration and smart devices.

As the first such satellites jointly developed by the Chinese mainland and Macao, the "Macao Science 1" satellites are used to improve the Earth's magnetic field exploration. Developed by the China Academy of Space Technology, the twin satellites carry payloads provided by the Macau University of Science and Technology. On May 21, 2023, the "Macao Science 1" satellites were successfully launched from the Jiuquan Satellite Launch Center in Northwest China’s Gansu Province by a Long March-2C carrier rocket developed by the China Aerospace Science and Technology Corporation.

Since its launch last year, "Macao Science 1" has generated a wealth of high-precision scientific data which has been used by scientists worldwide for research into Earth's interior, oceans and space.

As "Macao Science 1" satellites continue to collect data and refine its algorithms and software, the satellite’s scientific team plans to release updated versions of the real-time geomagnetic field model.
