The invention discloses a double-
satellite remote sensing system and method based on inter-
satellite laser communication and tracking and pointing integration, and relates to the technical field of space
remote sensing. The
system is composed of a first
satellite and a second satellite which fly back and forth in the same
orbital plane, and the first satellite and the second satellite are respectively provided with a multispectral camera, a hyperspectral camera and a
transmission system integrating tracking and pointing, inter-satellite
laser communication and multi-dimensional calibration functions. The
transmission system comprises an inter-satellite
laser communication load and a Beidou short message
backup load, a stable laser link can be established autonomously, and tracking and pointing precision is guaranteed through three calibration
modes of fixed star, satellite-ground and inter-satellite. The
system transmits trigger information through an inter-satellite laser link, and realizes collaborative observation of multispectral general survey-hyperspectral detailed survey. The method comprises the steps of calibration preposition, laser link establishment, collaborative observation, calibration maintenance and the like, and supports
data collaboration and emergency communication. The timeliness and observation precision of double-
satellite remote sensing are improved, and the high-reliability and high-timeliness requirements of scenes such as
earth surface anomaly monitoring and the like can be met.
