Who operates it
- SiReNT (Singapore Satellite Positioning Reference Network) is operated by the Singapore Land Authority (SLA).
- It is the official national GNSS reference network supporting Singapore’s geodetic and mapping needs.
Availability & access
- SiReNT is a subscription-based service, available to professional users such as surveyors, engineers, and government agencies.
- Provides real-time GNSS corrections via NTRIP as well as RINEX data downloads for post-processing.
Coverage & scale
- The network covers the entire island of Singapore with strategically placed reference stations.
- It is integrated into regional and global GNSS frameworks to maintain alignment with the International Terrestrial Reference Frame (ITRF).
Typical use cases
- Cadastral and engineering surveying.
- Infrastructure projects such as high-rise construction, tunnels, and transport systems.
- Precision agriculture, though limited due to Singapore’s urban context, mainly for research and experimental purposes.
- Scientific applications including geodetic monitoring and environmental studies.
How it’s used in practice
- Surveyors and engineers connect GNSS rovers to SiReNT’s NTRIP caster for centimeter-level RTK corrections.
- Researchers and technical users download RINEX data for geodetic and geophysical analyses.
Notes
- SiReNT is known for its reliability and role in supporting Singapore’s status as a smart city with advanced geospatial infrastructure.
- It also provides additional services like coordinate transformation tools and ionospheric data.
