Abstract

Global navigation satellite systems include various parts, such as control stations, Earth and space monitoring stations, and mobile navigation systems. The main results of the global navigation satellite system are the determination of time, location and control of navigation methods. Based on the vertical guidance approach procedure, local and global satellite navigation systems are used for positioning and precision approach in aviation instead of modern instrumental landing systems, as instrumental landing systems have errors in positioning and speed measurement. Differential corrections are determined using one or more reference stations. The concept of a single support station is simple, but the accuracy of position determination is lower. This article compares the methods of error correction of differential systems.
