A robust on-orbit geometric calibration (GC) method based on the rational polynomial coefficient (RPC) model for spaceborne segmented linear-array camera is proposed. Through a series of processing steps, including obtaining reliable ground control point (GCP) observations based a priori gross error elimination, constructing the adjustment model for GC parameters, GC for absolute geometric distortion, GC for relative geometric distortions among segmented charge-coupled devices (CCDs), and the correction for the created bias field-of-view (FOV) distortion, this invention is able to achieve robust GC for camera distortion, as well as accurate geometric splicing and registration of segmented CCDs under the same geometric benchmark.

The present disclosure relates to optical fiber plugs, optical fiber adapters, and optical fiber connector assemblies. One example optical fiber plug includes a ferrule, a sleeve, and a lock cap. At least one lock block is disposed on an inner wall of the lock cap. The at least one lock block is configured to be engaged and locked with a lock slot on an optical fiber adapter. Two stop blocks are disposed on the inner wall of the lock cap. A stop rod is disposed on an outer wall of the sleeve. The stop rod is located between the two stop blocks. The lock cap rotates relative to the sleeve within an angle range limited by the two stop blocks.
