  • Patent number: 12282104
    Abstract: A satellite attitude estimation system includes an infrared sensor configured to capture an infrared image of a target satellite for which an attitude is to be estimated. The system determines, in the captured infrared image, a first pixel having a largest luminance and a second pixel having a smallest luminance in the infrared image. The system associates the first pixels with first coordinates of a 3D structure of the target satellite, and associates the second pixels with second coordinates of the 3D structure of the target satellite. The system computes a first normal vector to a surface of the 3D structure for the first coordinates, and computes a second normal vector to the surface of the 3D structure for the second coordinates. The system estimates a direction of the target satellite to the sun before the infrared image was taken, using the computed first and second normal vectors.

  • Publication number: 20250123127
    Abstract: Disclosed are systems, methods, and structures that increase overall sensing reach of a DFOS system and reduces system cost without sacrificing sensed signal quality by employing a cascaded arrangement of DFOS interrogators and operating method providing backscattering DFOS, maintaining each span within a desired length which can advantageously be determined by signal quality, pulse rate, or other factors such as physical layout. The cascaded DFOS interrogators work independently while sharing the pulse light produced by the first interrogator in a cascaded series of interrogators. The light is amplified in successive fiber spans and a circulator may be employed to cut-off any backscattered signal.
