Application Writeups

This section describes each of the GPSTk applications. Each writeup serves as a reference and tutorial on using the application.

TECMaps Application

Summary

Program TECMaps reads RINEX data files containing extended RINEX observation types EL, AZ and SR or VR from several sites and at each epoch fits the vertical TEC data to a model of the ionosphere on a two-dimensional grid surface. Hardware TEC measurement biases are corrected, using input from the program IonoBias. The user can specify the type of grid, the type of TEC data and the model to be used. Output is in the form of files, one per epoch, which can be used to plot the 2D ionospheric TEC surface.
