Propagation Problems in Satellite Navigation

Kurzfassung

Satellite navigation is based on measuring the signal delay between transmission at the satellite and reception by the user receiver. Therefore, the modeling and correction of the additional delay due to the propagation through the atmosphere and mitigation of signal disturbances in the user environment play an important role for the accuracy of the derived position solution. The paper provides an overview about the mechanisms of the main propagation phenomena which are relevant for satellite navigation, their magnitude, temporal and regional variation and standard methods to correct and mitigate them.
