Introduced is a comprehensive optimization design about light and small push-broom &video integrated cameras for micro and nano satellites. In the system design, the integrated processing of satellite and ground is considered comprehensively, the RC system with large F-number is used to reduce the volume and weight. Commercial shelf strengthening technology is applied to achieve high performance and reduce cost. On-board data processing adopts digital TDI technology to realize push-broom and video integrated imaging of array camera, greatly improving imaging efficiency. The designed micro/nano remote sensing camera has a variety of working modes, such as video, push-broom, strip and so on, to meet the needs of different application scenarios. This technology has been applied in the design and development of micro and nano remote sensing payload, such as the OVS-1 video camera. High quality video and remote sensing images have been obtained in orbit. It has a broad application prospect in the market of commercial remote sensing payload.
