Analyzing the Impact of Dynamics on GNSS Receivers

Andreas Lipp, Stefan Vieweg, and Martin Weiser

Abstract:	Experience from the use of satellite navigation sys- tems in high precision dynamic positioning tasks has shown severe deficiencies in dynamic response even for equipment designed for such applications. Since satellite navigation will become an important tool for navigation of vehicles under dynamic conditions especially in air and road traffic, these deficiencies must be addressed. Although it seems to be well known that satellite navigation receivers have a dynamic behaviour, ac- curacy, continuity and integrity are often treated with “static” or “quasi-static” approaches and are extrapolated to a dynamic environment. This re- sults in a misunderstanding of the real capabilities of different satellite navigation receiver designs. It is shown, that it is possible in general to create dy- namic models of existing receivers to make them suitable for precise, dynamic applications. Nevertheless there are some situations which require an immediate error correction within the receiver, since it may be impossible to correct these errors afterwards in the navigation unit or by post pro- cessing. Some current receiver designs are prone to systematic errors caused by the dynamic environ- ment, which may impair or preclude the use of some types of integrity monitoring algorithms external to the receiver. Therefore the limitations and advantages of different receiver designs related to accuracy and reliability are presented by means of flight- and bench-tests.
