Topcon TopNET+ Reference Network Software

As the demands of modern satellite positioning continue to expand, Topcon is dedicated to meeting these new challenges. A key component of the modern GNSS industry is the fixed reference station, and Topcon is proud to offer a new, innovative solution to meet this growing need.

Features & Benefits:

  • Dual Frequency, Dual Constellation GNSS Reference Station Receivers
  • Reference Station Coordinates have been professionally surveyed and adjusted by Geodetic Surveyors
  • All Network Reference Stations are continuously monitored
  • Direct Connection to theĀ National Spatial Reference System
  • Reliable 24 hours a day, 7 days a week operation

Differential GPS (DGPS)

Real Time Differential GPS (DGPS) corrections are computed and broadcast from each reference station. Both Geographic Information System Professionals (GISP) and mapping customers will be connected automatically to the nearest reference station to maximize accuracy potential.

Real Time Kinematic (RTK)

The Real Time Kinematic (RTK) service will automatically connect your rover receiver to the nearest reference station using the low bandwidth, industry standard RTCM 3.0 data format.

Modeled Network Solutions (MRS)

TopNET server software constantly collects data from all available GNSS reference stations and forms a correction field, where precise values can be calculated at any point inside the field. From these corrections and user’s coordinates sent by the Rover (standard NMEA-0183 GGA message), TopNET simulates a reference station receiver position located close to the moving rover.  The generated data are streamed contantly to the rover using the industry standard RTCM 3.0 data format and used for obtaining precise solutions.
