Overview
GNSS (Global Navigation Satellite System) and GPS (Global Positioning System) are geospatial technologies that provide high-precision positioning, movement tracking, and elevation data for infrastructure monitoring, construction, and large-scale surveying applications.
We integrate RTK (Real-Time Kinematic) and PPK (Post-Processed Kinematic) GNSS/GPS solutions to deliver centimeter- to millimeter-level accuracy, ensuring structural integrity, real-time monitoring, and proactive risk mitigation.
Our GNSS-powered solutions are widely used in infrastructure projects, construction, mining, transportation planning, and disaster risk management—ensuring safe, efficient, and data-driven decision-making.
What is GNSS and GPS Surveying?
GNSS vs. GPS: Understanding the Difference
- GNSS is an umbrella term encompassing multiple satellite positioning systems, including:
- GPS (USA)
- GLONASS (Russia)
- Galileo (EU)
- BeiDou (China)
- GPS, on the other hand, refers specifically to the United States-operated satellite system.
By combining multiple GNSS satellite constellations, we achieve higher accuracy, wider coverage, and improved reliability even in challenging environments like urban canyons, tunnels, and remote areas.
Key Features of GNSS/GPS Surveying
✔ Centimeter-Precision Accuracy – Achieved using RTK and PPK correction techniques.
✔ Wide Coverage & Real-Time Tracking – Suitable for remote sites, highways, and high-risk zones.
✔ Deformation & Settlement Monitoring – Detects micro-movements in critical infrastructure.
✔ Integration with Other Surveying Methods – Works alongside laser scanning, aerial mapping, and real-time data loggers.
✔ Secure, Cloud-Based Data Access – Enables remote monitoring and automated reporting.
✔ Monitoring System Implementation – With the appropriate software and structured database, GNSS receivers can be used as real-time monitoring devices for infrastructure and geotechnical stability.
