| Popis: | Satellite navigation systems require of knowing satellite positions with a high level of accuracy. Unlike other GNSS constellations, GLONASS ephemeris can not be directly obtained from broadcast navigation messages at any desired epoch. A data post process is required to compute the user solution. The present MSc thesis focuses on implementing an algorithm to compute GLONASS coordinates and clocks at any epoch from the broadcast navigation message and allows its accuracy assessment and error characterization, with respect to precise products. Analyzing the resulting data provides values of coordinate and clock differences for short and long terms. The error characterization procedures give a comparison between different GLONASS satellites, allowing to obtain best and worst cases in relation to their coordinates and clock offsets accuracy. |
