Abstract: A system for determining a geolocation of a mobile object movable through a terrain in a Global Navigation Satellite System (GNSS) signal attenuated environment is provided herein. The system may include: a sensor mountable on the mobile object and configured to obtain a dataset of a scene including three or more scene points; a digital storage unit configured to store a semantically segmented reference dataset representing the scene, the semantically segmented reference dataset having a reference coordinate system; and a processing unit configured to: determine three or more distances between the sensor and the three or more scene points; generate, based on the determined distance, an object semantically segmented projection dataset comprising a projection of the detected three or more scene points in the reference coordinate system; register the semantically segmented projection dataset with respect to the semantically segmented reference dataset; and identify the respective scene points real-world geographical locations.

Abstract: Aspects of embodiments to systems and methods for navigating a mobile platform using an imaging device on the platform, from a point of origin towards a target located in a scene, and without requiring a Global Navigation Satellite system (GNSS), by employing the following steps: acquiring, by the imaging device, an image of the scene comprising the target; determining, based on analysis of the image, a direction vector pointing from the mobile platform to the target; advancing the mobile platform in accordance with the direction vector to a new position; and generating, by a distance sensing device, an output as a result of attempting to determine, with the distance sensing device, a distance between the mobile platform and the target. The mobile platform advanced towards the target until the output produced by the distance sensing device is descriptive of a distance which meets a low-distance criterion.
