SAR-based augmented integrity navigation architecture

This paper presents selected results obtain under SARINA project. SARINA is a SAR-based Augmented Integrity Navigation Architecture proposed by authors of this paper. The main goal of the SARINA project was designing and assessing a novel aircraft Inertial Navigation System (INS) for missile and UAV that will make use of features extracted from SAR/InSAR imagery and on-board terrain landmark database in order to ensure robustness against uncompensated IMU errors due to possible GPS lack of.
