摘要： 北极区域海冰是影响北极船舶航行安全的重要因素, 由于该区域现场观测站点少, 卫星遥感成为监测北极海冰变化的主要手段。为满足北极海域重点区块遥感观测的需求, 结合海洋卫星轨道预测技术和海岸带成像仪的载荷特点, 本文提出了一种多区域成像的卫星探测任务规划算法。简化的轨道预报模型和规划算法均为自主设计、独立编程, 脱离商用软件的约束, 自动化程度高, 经过海洋一号C卫星的应用实践, 验证了该算法满足近实时的观测需求, 改变了以往无差别接收任务规划的不合理局面, 有效提高了卫星资源的应用效能, 为北极航运提供更好的支撑服务。

Abstract:

Arctic sea-ice has a great influence on ship navigation. Since lack of regional field observation, high resolution remote sensing data becomes a major method for monitoring sea-ice change. To satisfy precise observation requirement on polar areas, this paper shows an auto-matching algorithm for detecting schedule management. Based on simplified satellite orbit-forecasting model and payload technical specification, this algorithm uses monitoring-coverage factor to get an optimal selection. The unique developed software could replace business software and apply on HY-1C satellite CZI. With advantage in near-real-time (NRT) sea-ice monitoring, it will provide more support to vessels sailing in the Arctic ocean and conserve satellite resource.
