Analysis explores low-orbit augmentation and its impact on navigation signal reliability for GLONASS, indicating improved Earth coverage capabilities.
Modern global navigation satellite systems in medium-altitude and geostationary orbits have two significant drawbacks. The first is the degradation of the availability level (according to the criterion of the geometric factor by location (PDOP) ≤ 6) and the average value of the geometric factor with an increase in the angle of reception of navigation signals due to natural or anthropogenic terrain, which leads to both a decrease in the accuracy of navigation definitions and a complete failure of navigation. The second is the low level of the navigation signal in the zone of use (the Earth's surface and atmosphere), which, with a significant level of radio interference, leads to the impossibility of navigation definitions.
