Singapore-Up to four new Coastal Global Navigation Satellite System (GNSS) reference stations will be installed across the island for data collection to better monitor changes in land and sea levels in Singapore.

The move will take place on Monday (6 June) under a new four-year partnership signed between the Singapore Land Authority (SLA) and the Singapore Earth Observatory (EOS) at Nanyang Technological University.

Additional stations are expected to contribute to and enhance the existing network of nine reference stations across the island managed by the SLA.

These are part of SLA’s Singapore Satellite Positioning Reference Network (SiReNT) and are the national infrastructure for accurate positioning, mapping, and navigation.

Founded in 2008, the NTU Observatory studies earthquakes, volcanic eruptions, tsunamis and climate change events around Southeast Asia.

The agreement also gives the observatory access to archived historical GNSS data for more than 10 years.

Dr. Feng Lujia, 40, a senior researcher at the observatory, said historical data better predict how future events, such as large regional earthquakes, could change the height of Singapore’s land. I told The Straits Times that it would be useful.

Dr. Victor Khoo, 52, director of the Survey and Geomatics division of the SLA, processes signals received by ground reference stations to enable researchers to measure land height and sea level changes in several locations around Singapore. Said that you can.

The observatory also hopes to utilize and compare water vapor data collected by GNSS and local meteorological services to study rainfall and possible flood patterns.

This study is expected to contribute to the Singapore National Sea Level Program, which aims to support national sea level forecasts in the future.

Researchers can also improve the accuracy of data collection. GNSS can continuously collect data to measure annual changes in terrain height up to millimeters.

Dr. Kuu said: “We would like to adopt geospatial technology and infrastructure to provide efficient and accurate long-term data collection and solutions to support Singapore’s sustainable development.

“This will help protect the coast and mitigate the effects of rising sea levels.”
