Abstract: A distributed secured database system includes a ledger, a transmitting device, edge devices, and a time synchronization source. An evolving nonce is generated at the transmitting device and the edge devices. The evolving nonce is time-synced across the transmitting device and the edge devices. A hash value is generated at the transmitting device and the edge devices using the evolving nonce. The hash value is verified at the transmitting device and each of the edge devices during a particular time frame. A block is added to the distributed secured database system when the hash value is verified by the transmitting device and the edge devices.

Abstract: Technology for facilitating position determination is disclosed. A satellite with a known location can activate a light source on the satellite operable to emit light. The satellite can emit the light for a defined period of time to enable a receiver to detect the light and determine a geographical location using the light emitted from the satellite.

Abstract: Systems, devices, methods, and computer-readable media for horizon-based navigation. A method can include receiving image data corresponding to a geographical region in a field of view of an imaging unit and in which the device is situated, based on the received image data, generating, by the processing unit, an image horizon corresponding to a horizon of the geographical region and from a perspective of the imaging unit, projecting three-dimensional (3D) points of a 3D point set of the geographical region to an image space of the received image data resulting in a synthetic image, generating, by the processing unit, a synthetic image horizon of the synthetic image, and responsive to determining the image horizon sufficiently correlates with the synthetic image horizon, providing a location corresponding to a perspective of the synthetic image as a location of the processing unit.
