The Design of Cone and Pendulum Scanning Mode Using Dual-Camera with Multi-Dimensional Motion Imaging Micro-Nanosatellite

This paper focuses on the design of a new optical cone and pendulum scanning imaging mode for micro-nanosatellites. kind satellite uses high-resolution camera with small plane to achieve ultra-wide coverage through three-dimensional motion camera’s wobble, spin, orbital motion. First, this designs single-camera constant speed OCPSI (optical imaging) mode. On premise ensuring coverage, parameters are derived. Then, in order improve performance quality system, dual-camera variable is designed. In method, reduce overlap ratio, oscillated at speed. Turn cameras turn same time minimize overlap. details these working modes. The simulation experiment carried out using orbit 500 km, focal length 360 mm, pixel size 2.5 ?m, resolution [5120 × 5120], number frames hoop 10, initial inclination angle 30°. has an effective swath 1060 km ground sampling distance 5.3 m. width 966 under conditions. Finally, prototype theory We choose 3.45 [1440 1080], 25 mm. was 10°, 3, height 11 experimental result that reaches 10.8 Compared traditional push-broom camera, 1.64 m increased by seven times, 3.83 three times compared whisk-broom study innovatively integrates into aerospace remote sensing provides reference research realization micro-nano satellites.
