Top NET+ 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 & Benefi

  • 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 the 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 constantly to the rover using the industry standard RTCM 3.0 data format and used for obtaining precise solutions
