RTK via cellular network
Topnet Live is a global GNSS correction service that provides precise positioning data to surveyors and construction teams using satellite-based systems. Ideal for roving crews and heavy equipment with GNSS capabilities, it supports high-accuracy tasks such as field surveys, site layout, earthworks, paving, and as-built reporting—ensuring reliable performance wherever the job takes you.
GNSS receivers are subject to errors from satellite geometry, atmospheric interference, and signal delays. Without correction services, positioning data can be off by several meters—leading to construction clashes, costly rework, safety hazards, and potential property boundary disputes. GNSS correction services eliminate these inaccuracies, ensuring precise, dependable positioning for every stage of your project.
Topcon’s reference station network leverages all five major GNSS satellite systems—GPS, GLONASS, Galileo, QZSS, and BeiDou—to deliver superior global coverage, enhanced accuracy, and unmatched reliability for your positioning needs.
Realpoint enhances satellite positioning using a network of regional reference stations, delivering centimeter-level accuracy with near-instant start-up when within network range.
SkyBridge offers seamless PPP infill, maintaining reliable positioning in areas with limited RTK network access—ensuring uninterrupted workflow across challenging locations.
Starpoint Pro delivers global, centimeter-level accuracy using a single GNSS receiver and a global reference framework. While start-up is slower than RTK, it provides consistent, high-precision service anywhere in the world—independent of local infrastructure.
