Abstract:	Researchers have begun investigating the potential use of image-based navigation systems for applications where Global Navigation Satellite Systems (GNSS) signals are not available or should not be used. Independence from external radio-frequency transmissions and potentially low-cost implementations of camera and image processing suites are key advantages of image-based systems. However, while the concept of integrity is well-understood for many GNSS applications, to the best knowledge of the authors, no one has fully addressed rigorous integrity quantification with respect to image-based navigation systems. This paper details the research into the impact of attitude in an image-based integrity framework and describes how image-based integrity can be calculated for both known and unknown attitude cases. The results show that, from an integrity perspective, there is a significant benefit to having known attitude information.
