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.
