Abstract: A star tracker determines a location or orientation of an object, such as a space vehicle, by observing unpolarized light from one or more stars or other relatively bright navigational marks, without imaging optics, pixelated imaging sensors or associated pixel readout electronics. An angle of incidence of the light is determined by comparing signals from two or more differently polarized optical sensors. The star tracker may be fabricated on a thin substrate. Some embodiments have vertical profiles of essentially just their optical sensors. Some embodiments include micro-baffles to limit field of view of the optical sensors.

Abstract: Methods and apparatus automatically determine a location, such as of an aircraft or spacecraft, by matching images of terrain below the craft, as captured by a camera, radar, etc. in the craft, with known or predicted terrain landmark data stored in an electronic data store. A star tracker measures attitude of the camera. Optionally, a rangefinder measures altitude of the camera above the terrain. A navigation filter uses the attitude, and optionally the altitude, to resolve attitude, and optionally altitude, ambiguities and thereby avoid location solution errors common in prior art terrain matching navigation systems.

Abstract: An optical communications system comprises a first node comprising a phased array transmitter for generating an optical beam and a receiver, and a second node comprising a phase conjugate mirror for returning the optical beam to be detected by the receiver of the first node. The phased array transmitters allow for electronic steering of the beams in a way that is much faster and with a potentially smaller physical footprint than the mechanical systems. The phase conjugate mirrors return the received beams of photons back over the exact path they were sent from the phased array transmitters, ensuring continuity of communication even in the presence of atmospheric turbulence.

Abstract: A navigation system includes a monocentric lens and one or more curved image sensor arrays disposed parallel and spaced apart from the lens to capture respective portions, not all, of the field of view of the lens.

Abstract: Scattered light in the sky (sky glow) from light sources at one or more known geographic locations is used as reference point(s), from which geographic location of a system observing the sky glow is automatically ascertained. The light is scattered by particulates in the atmosphere. An upward looking camera captures an image of the sky, including the sky glow. A search engine automatically searches a catalog of modeled or pre-stored sky glows for a model that matches the image. Each model is associated with a geographic location. The models characterize each sky glow, such as in terms of color, intensity, etc., as the sky glow would appear from the associated geographic location. If a matching model is found, within a predetermined match criterion, the system outputs the geographic location associated with the matching model. Optionally, the geographic location is used to select and display a map of the geographic location.

Abstract: Methods and apparatus ascertain a geographic position based on topographic contours of ocean surfaces. Observed ocean topographic contours are matched to predicted ocean topography and/or ocean topographic information stored in a database. Such systems and methods do not necessarily require INS, GPS, RF beacons, optical beacons or celestial sightings. These systems and methods may be used as references to correct INS. These systems and methods may be used to ascertain a geographic location of an aircraft, spacecraft, watercraft, landcraft (vehicle), person or the like. Similarly, these systems and methods may be used as part of a guidance system for guiding a craft to a destination. These systems and methods may be used in tandem with, or as backups for, other types of navigation or guidance systems or as one input to a navigation filter.

Abstract: A star tracker has an electronically steerable point of view, without requiring a precision aiming mechanism. The star tracker can be strapped down, thereby avoiding problems associated with precision aiming of mechanical devices. The star tracker images selectable narrow portions of a scene, such as the sky. Each stellar sighting can image a different portion of the sky, depending on which navigational star or group of navigational stars is of interest. The selectability of the portion of the sky imaged enables the star tracker to avoid unwanted light, such as from the sun.

Abstract: A digital camera optically couples a monocentric lens to image sensor arrays, without optical fibers, yet shields the image sensor arrays from stray light. In some digital cameras, baffles are disposed between an outer surface of a monocentric lens and each image sensor array to shield the image sensor arrays from stray light. In other such digital cameras, an opaque mask defines a set of apertures, one aperture per image sensor array, to limit the amount of stray light. Some digital cameras include both masks and baffles.
