    Abstract: Systems and methods that enable a targeting system operator, with no access to GPS signals, to self-locate using one or two landmarks and then geolocate an object-of-interest (OOI) using its own position and attitude and the range to the OOI. In the absence of GPS signals, the coordinates of the position of the targeting system can be calculated using a self-location algorithm either: (1) based on a measured direction and a measured range to one landmark and known coordinates of the position of the landmark; or (2) via triangulation based on two landmarks with respective known coordinates and respective measured headings. The coordinates of the position of the OOI can then be calculated using a geolocation algorithm based on the calculated coordinates of the position of the targeting system, and a measured direction and a measured range to the OOI. The calculated coordinates of the position of the OOI can then be sent to a weapons programmer by digital or voice message.

    Abstract: The general field of the invention is that of systems for detecting the posture of a mobile object. The systems according to the invention comprise a fixed electro-optical device comprising an emission source and a photosensitive sensor. The optical corner cube is arranged on the mobile object. The entry face of the corner cube has a predetermined geometry, the light coming from the source and reflected back by the corner cube forming a luminous contour on the matrix sensor. The fixed electro-optical device comprises an optical element with a known shape and location, which is placed in the vicinity of the said source and is arranged so as to form a dark zone in the central part of the luminous contour. The detection system comprises analysis means determining the position and the orientation of the mobile object from knowledge of the vanishing points of the luminous contour and the position and shape of the dark zone.

    Abstract: A Doppler lidar sensor system includes a laser generator that produces a highly pure single frequency laser beam, and a frequency modulator that modulates the laser beam with a highly linear frequency waveform. A first portion of the frequency modulated laser beam is amplified, and parts thereof are transmitted through at least three separate transmit/receive lenses. A second portion of the laser beam is used as a local oscillator beam for optical heterodyne detection. Radiation from the parts of the laser beam transmitted via the transmit/receive lenses is received by the respective transmit/receive lenses that transmitted the respective part of the laser beam. The received reflected radiation is compared with the local oscillator beam to calculate the frequency difference therebetween to determine various navigational data.

    Abstract: Systems, methods, and other embodiments associated with distance based position measurement are described. In one embodiment, an apparatus is configured to be positioned proximate a feature of interest. The apparatus includes a laser distance meter (LDM) configured to emit a laser beam and to determine first and second distances between the LDM and first and second targets. The first and second targets have known positions in three dimensions with respect to a reference plane from which the LDM is located. The apparatus also includes a trilateration unit configured to compute a two dimensional position of the LDM relative to the targets based, at least in part, on the first and second distances.

    Abstract: In an optical position detection device, when light source sections emit detection light, a light detecting section detects detection light reflected from a object to detect the coordinates of the object. When seen from the detection space, the light detecting section is located inward from a plurality of light source sections, and each of the plurality of light source sections includes first and second light emitting elements. Therefore, the position of the object can be detected on the basis of a comparison result of the received light intensity in the light detecting section when the first light emitting element is turned on and the received light intensity in the light detecting section when the second light emitting element is turned on in both the case where the object is located outside a region between the light source sections and the case where the object is located inside the region.
