摘要:
A line scanner scans in a cross track direction and moves forward on a platform in an along track direction. The line scanner includes a plurality of detectors forming a left array and a plurality of detectors forming a right array. The left array and the right array are tilted away from a line formed in the along track direction. The left array is configured to detect scene radiance from a surface of an object when the line scanner is scanning the surface on the right side of the line formed in the along track direction. The right array is configured to detect scene radiance from the surface of the object when the line scanner is scanning the surface to the left side of the line formed in the along track direction. The detectors in each respective array are configured to simultaneously detect the scene radiance.

Systems for establishing electrical interconnections for helmet-mounted devices are disclosed. A system for establishing an electrical interconnection for a helmet-mounted device is comprises a first interconnect mechanism coupled to one of a helmet and the helmet-mounted device, and a second interconnect mechanism coupled to the other one of the helmet and the helmet-mounted device. The first interconnect mechanism comprises a first frame, a biasing member, a plurality of first electrical contacts, and a first projection. The second interconnect mechanism comprises a second frame, a plurality of second electrical contacts, and a second projection. As the first interconnect mechanism is moved toward the second interconnect mechanism, the contact between the first projection and the second projection causes rotation of the first frame in a direction opposite the predetermined rotational direction.

Systems for mounting a helmet-mounted device to a helmet are disclosed. One such system comprises a frame configured to be movably coupled to the helmet, and an interconnect mechanism rotatably coupled to the frame. The interconnect mechanism is configured to receive the helmet-mounted device. The interconnect mechanism is rotatable relative to the frame between a use position for the helmet-mounted device and a stow position for the helmet-mounted device.
摘要:
Embodiments are generally directed to anti-spoofing techniques for satellite navigation systems. In general, the anti-spoofing techniques use codeless or semi-codeless tracking of encrypted satellite signals to generate measurements that can be used to perform consistency checks to received non-encrypted signals. The consistency checks will detect if the non-encrypted signal is a genuine satellite signal or a spoofing signal.
