Topcon Positioning Systems has expanded its Topnet Live reference station network by adding 200 new geodetic stations across the United States. This expansion enhances the availability of centimeter-level accuracy for industries requiring precise positioning, such as engineering, surveying, construction and agriculture.

The upgraded network provides advanced network corrections that optimize operational workflows in various sectors. The enhanced infrastructure supports emerging technologies such as automated turf management, precision line marking, imaging systems and UAV operations for mapping and delivery.

This expansion builds upon previous efforts throughout 2024, resulting in a 30% increase in Topnet Live’s total coverage in the United States. The network now offers comprehensive, network-modeled solutions that cater to a wide range of professional requirements across multiple market segments.

The Topnet Live network utilizes Networked Transport of RTCM via Internet Protocol (NTRIP) to stream GNSS corrections data via the Internet for RTK positioning. This technology allows for centimeter-level accuracy by mitigating errors from factors such as ionospheric disturbances, satellite clock deviations and orbit inaccuracies.
