TopNEXT GNSS Reference Network Real – Time Data Services Explained

TopNEXT DGPS

Real Time, differential GPS corrections (DGPS) are computed and broadcast from each reference station. GIS and mapping customers will be connected automatically to the nearest reference station to maximize accuracy potential.

RTK

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

Network RTK

TopNET collects data from all the available 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 located close to the Rover. The generated data are sent to the Rover using the industry standard RTCM 3.0 data format and used for obtaining precise solutions.
