Celestial Navigation for Drones (mdpi.com)
Celestial navigation is rarely seen in modern Uncrewed Aerial Vehicles (UAVs). The size and weight of a stabilized imaging system, and the lack of precision, tend to be at odds with the operational requirements of the aircraft. Nonetheless, celestial navigation is one of the few non-emissive modalities that enables global navigation over the ocean at night in Global Navigation Satellite System (GNSS) denied environments.

New laser could cram GPS alternative into a shoebox (ieee.org)
Dramatically more sensitive motion sensors could help ships keep track of their positions at sea, even in rough weather or when a military opponent jams GPS signals. However, these advanced sensors are typically lab-scale in size. Now researchers have developed a new laser system to help make these sensors fit in a shoebox, as well as potentially mass-producible.
