Abstract
The use of GNSS technologies has been spreading over time up to a point in which a huge diversity of applications require their use. Due to this demand, GNSS has turned into a more reliable technology, as multiple aspects of it have evolved. Integrity has become a vital aspect of being considered when using GNSS. The following document gathers and shows different aspects of integrity in terms of GNSS. The paper mainly focuses on the description of different receiver autonomous integrity monitoring methods. For this purpose, basic concepts and possible GNSS error sources (and their corresponding solutions) are introduced. Afterward, an explanation and a classification of the integrity monitoring techniques is given, where the fault detection and exclusion methods and different protection level computation formulas are analyzed.
Highlights
Nowadays, the demanding requirements of industry and society urge positioning systems to be safer, more reliable, and even faster
This paper focuses on the review and explanation of the different fault detection and exclusion (FDE) methods found in the literature to improve the integrity of the estimated GNSS PVT solution
This means that integrity is dependent on the quality of the input information/signals and the detection and mitigation techniques implemented in the positioning algorithm for the multiple error sources that receivers need to handle
