WinFrog GPS Calculations Module

The WinFrog GPS Calculations Module provides enhanced positioning and extensive differential GPS calculation capabilities. Available as an extension to the core WinFrog program, this module can combine solutions based on multiple reference stations or multiple RTCM sources into one network solution.

Using RTCM corrections from up to five stations, input from the same source (e.g., satellite) or from multiple sources, this module computes a multi-reference DGPS solution. The use of multiple reference stations provides increased redundancy, reliability and quality assurance benefits.

The GPS Calculations Module allows you to get the most precise and consistent positioning available from your GPS. It takes the accuracy of standard DGPS and enhances the solution, ensuring consistently accurate position solutions with extensive quality control monitoring features. This module is particularly useful on projects using long DGPS baselines and where increased redundancy or quality control is required.
