The Topcon reference station network uses five GNSS satellite systems: GPS, GLONASS, Galileo, QZSS, and BeiDou. This ensures the best global coverage, accuracy, and reliability.
Services for wherever work takes you
Topnet Live is a global GNSS correction service that delivers positioning data to surveyors and construction teams whose projects use satellite positioning. Roving surveyors and construction workers, along with heavy construction equipment with satellite navigation systems, use this service for high-accuracy applications such as field surveys, jobsite layout, earthworks, paving, and as-built reporting.
Full-constellation service
What are RTK and PPP, and why do they matter?
RTK (Real-Time Kinematic positioning)
Realpoint uses a network of regional reference stations to enhance satellite positioning data. Start-up time is nearly instant when in range of the network.
Constant coverage
SkyBridge provides seamless PPP infill support in areas where RTK coverage is limited.
PPP (Precise Point Positioning)
Starpoint Pro calculates positions at the centimeter level using a single receiver in a global reference framework. It has a slower start-up speed, but provides service anywhere on the planet, independent of local networks.
Topnet Live service options
Choose RTK, PPP, or bridge both with borderless service that automatically switches between regional GNSS reference networks. Several subscriptions are available on the Topnet Live website.
