TASGNSS

This is a GNSS positioning utility that implements Weighted Least Squares (WLS) positioning algorithm.

Overview

The tool processes GNSS observations to calculate receiver position, velocity, and clock parameters using WLS method. It supports multiple GNSS systems and includes necessary corrections for practical applications.

Key Features

  • Weighted Least Squares positioning
  • Support for multiple GNSS constellations
  • Atmospheric delay corrections (ionospheric and tropospheric)
  • Satellite clock and relativistic effects correction
  • Iterative solution until convergence

Documentation

For detailed technical information about the WLS algorithm and GNSS corrections, please see the Appendix.
