The Influence of the Signal Distortions on the Satellite Based Navigation Systems

摘要

The Global Navigation Satellite Systems (GNSS) is widely used in numerous applications that include the agricultural production, aviation, maritime and automobile navigation. GNSS is also involved with the lifesaving application such as the search and rescue. The GNSS is continuously developed with the additional satellite constellations being added to the orbit and the new frequencies are adopted. The new frequencies and the new signal are introduced to eliminate the largest errors that were ever experienced in the GNSS applications and improve the accuracy in terms of the position calculations. The signal distortions are caused by the GNSS signal degradation and the signal multipath becomes the prominent concern. The purpose of this paper is to assess and quantify the impact of the nominal signal interference in the in the GNSS receiver and further provide the brief description and the algorithm of the signal from the space. The results will be open and available for domain use for the researchers or institutions that are studying toward the solution based approach of increasing the GNSS performances. Furthermore it will provide an option to quantify the distortion impact to the GNSS.
