吉林一号轻型高分辨率遥感卫星光学成像技术
Optical imaging technology of JL-1 lightweight high resolution multispectral remote sensing satellite
摘要
Abstract
In order to realize light-weight design as well as multi-spectral and multi-mode imaging with high resolution of JL-1 optical remote sensing satellite, advanced integration design method and payload centric concept were adopted, thus indexes, scheme and key techniques of JL-1 were given and in-orbit multi-mode optical imaging was achieved.The mass of JL-1 is approximately 450 kg, the payload ratio reaches 40% and the attitude maneuver speed of JL-1 can be 2.1 (°)/s, which enable stereo and piece imaging.With the capacity of 800 GB on-board FLASH storage and double X band 600 Mbps telemetry, JL-1 satellite can collect up image data over nearly 150,000 km2 daily.The satellite was launched in 2015, and can collect images with resolutions of 0.72 m (PAN) and 2.88 m (MS) in 656 km sun synchronous orbit, which meet the requirements of commercial movements.关键词
