The ‘BIO.PNT’ project, funded by the European Space Agency (ESA), has developed a water quality monitoring system that combines biosensor and positioning, navigation and timing (PNT) technologies. The system enables the association of PNT data with detected organophosphate contamination in fresh water.

Researchers at the Technical University of Denmark (DTU) have developed a method to monitor daily ice loss in Greenland using data from 61 GPS stations installed on the bedrock around the island. This approach allows for precise tracking of ice melt, providing day-by-day data that enhances understanding of sudden changes in ice mass, especially during the summer.

Researchers from Columbia University Climate School Lamont-Doherty Earth Observatory have published a 4-part field report from ongoing field work in the Tea Region of Bangladesh. The team is using GNSS to measure tectonics, earthquake hazard, as well as land subsistence in the face of climate change and sea-level rise.
