Eliminating on-site base stations, TopNETlive is increasingly employed in high-profile construction projects. Large highway construction projects, airport runways and machine control operations all benefit from the reliable accuracy and performance of TopNETlive GNSS reference networks.
TopNETlive networks deliver consistent, high-precision positions to precision agriculture machines used in applications across the crop cycle such as soil preparation, seeding and crop care. Equipped tractors, sprayers, spreaders and harvesters benefit from fast initializations and reliable positioning any time of the day or night.
TopNETlive delivers high-accuracy positioning to professional surveying and engineering applications such as land surveys, engineering surveys, GIS and mapping. TopNETlive removes the need for individual base stations, dramatically increasing production and safety.
OEM – System Integrators
TopNETlive is a global positioning correction service for system integrators, product designers and OEMs. It is ideal for scalable, precision GNSS positioning needs for applications such as automotive, Industrial IOT and autonomous robotics.
In order to provide precise positioning accuracy, a GNSS receiver needs to compensate for inaccuracies caused by satellite constellations, receiver hardware and atmospheric conditions. These inaccuracies can be calculated by a network of fixed reference stations that constantly receive GNSS data.
This correction information is then broadcast to GNSS receivers as a correction service. TopNETlive is Topcon’s GNSS correction service and consists of the reference station network, correction calculation software and the correction broadcast service.
Topcon manages, operates and monitors all TopNETlive reference networks.
Real-Time Kinematic positioning (RTK) is a method to enhance the precision of position data derived from satellite-based positioning systems. RTK works through a network of stations covering local countries. Single Base RTK provides fast and accurate correction from either a specific reference station or the nearest one. Network RTK delivers the correction from a number of stations in a local network of reference stations.
Precise Point Positioning (PPP) is a method to calculate precise positions at the few-centimeter level using a single receiver in a global reference framework. PPP delivers great accuracy with slower start-up speed, but provides service anywhere on the planet, independent of local networks.
Providing the Best of RTK and PPP
SkyBridge allows subscribers to combine RTK and PPP correction services.
Provides greater accuracy and quick start-up time.

The TopNETlive correction service is broadcast to customer receivers in two ways:
- NTRIP – The internet, typically using a mobile phone SIM card data link
- L-Band – Direct communication from a satellite
Customers have both options and can use whichever is most convenient.
As an additional service, the raw data (RINEX) from the networks is available to download. There is also an online correction processing service for specialist applications.
Both types of networks offer advantages and disadvantages. That is why Topcon designed and developed a service to provide its customers access to both systems simultaneously, even automatically switching between as reception changes. This means the customer always has the best of both systems and a truly global service.
The Topcon reference station network uses all four GNSS satellite systems: GPS, GLONASS, Galllieo and BeiDou. This ensures the best accuracy and reliability, often referred to as a full-constellation service.
Truly Global Solution
TopNETlive is a truly global solution, providing correction service anywhere with the combination of global PPP and local NRTK networks
NRTK networks are operated by Topcon and its partners to provide coverage in all major regions of the world
Customers can have a single subscription that provides borderless service which automatically switches between NRTK networks
TopNETlive is managed by Topcon’s own network and geodesy experts, which ensures a precise and reliable always-on service
Flexible and Tailored
Topcon’s OEM GNSS boards can be preconfigured for immediate use by system integrators' customers, with flexible subscription/licensing options to suit the exact need
The entire solution is designed to be scalable, so system integrators do not need to limit locations or numbers of customers
