Software Package for Solving Navigation Problem Using Systematic Instrumental Error Correction

Satellite navigation is an essential part of our everyday life and is used in a variety of applied research projects. Satellite navigation is based on measuring signal propagation from a satellite to a GNSS receiver, and thereby it is important to use precise models and time corrections to get accurate results. This paper describes the software package that we have developed for solving the satellite navigation problem. It provides a wide choice of models for measuring pseudorange bias components as well as the analysis of the systematic instrumental error of the navigation receiver. The paper presents the results of solving the satellite navigation problem for different scenarios.
