Short summary
We developed two open tools that simplify and modernize the processing of satellite positioning data used to monitor volcanoes and earthquakes. They automatically collect and convert data from different instruments into a common format, making near real-time analysis easier and more reliable. These tools enable observatories in remote areas to enhance their ability to track ground movements and gain a deeper understanding of natural hazards.
