Satellite GLONASS orbit integration and analysis
Satellite navigation systems rely on precise knowledge of satellite positions. Galileo,GPS and BeiDou satellite coordinates are computed from pseudo-Keplerian elements. In contrast, GLONASS satellite are computed by interpreting the orbit from initial conditions of position and velocity using a four...

| Sumario: | Satellite navigation systems rely on precise knowledge of satellite positions. Galileo,GPS and BeiDou satellite coordinates are computed from pseudo-Keplerian elements. In contrast, GLONASS satellite are computed by interpreting the orbit from initial conditions of position and velocity using a fourth-order Runge-Kutta method. This master thesis aims to develop an algorithm that can compute GLONASS coordinates and clocks at any epoch using the broadcast navigation message. The algorithm analyzes the computed coordinates and key aspects of the satellite orbit derivation, such as external forces affecting the orbits. Through the analysis of the obtained data, coordinate and clock differences can be determined for both short and long terms, the data can be compared with other navigation products and the nature of these external forces can be identified. |
