    摘要:

    面向多種災害頻發的應急觀測任務,現有地面應用系統響應能力無法滿足常態化的高時效性觀測需求。為發揮風云四號B星(FY-4B)快速成像儀靈活、快速的載荷性能優勢,通過設計應急響應與常規觀測一致的觀測模式及時間表,規劃中國及全圓盤區域,建立智能決策觀測任務的自動化星地指揮調度系統,在保證衛星安全前提下實現載荷應急觀測快速部署,全業務流程響應平均不超過30 min。該系統有效減少頻繁變更觀測任務所引起的星地資源壓力,保證遙感數據連貫性,已在汛期服務及各類災害氣象保障中發揮重要數據支撐作用。

    Abstract:

    Spacebased earth observation has the advantages of extensive coverage and the potential for using multiple payloads for detection, offering technical support for increasingly frequent disaster emergencies. FY-4B, represents the first operational satellite of China’s second generation geostationary orbit quantitative remote sensing meteorological satellite. Its high-speed imager’s primary function is to conduct high-frequency emergency observations for sudden natural disasters such as severe convection, typhoons and earthquakes. Given the regular occurrence of various disasters, the response capability of current ground application systems fails to meet the needs for normalised effective observation. Therefore, to capitalise on the benefits of flexible and speedy observation performance, we adopt a mix of static and dynamic task planning observation strategies. We have designed, within a one-minute timeframe, an observation range of 2000 km (South-North)×1800 km (East-West) that aligns with emergency response and convention observation requirements. This is for a West-East single direction scanning imaging observation mode and a 15-minute period observation schedule. Included are areas, position, and calibration missions planned with 37 units in the China region and 119 units in the full disk region. Efficient observation is achievable only through the rapid and dynamic switching of payload areas. Furthermore, it is crucial to minimise the response time of the satellite-ground system as much as possible. To this end, we carry out a comprehensive conflict analysis according to the existing satellite platform and payload operation schedule. We establish a full process intelligent observation task decisionmaking and automatic switching system, adopting a dual-thread concurrent automatic operation. This aims to achieve unified command and scheduling of the entire business process, including high-speed imagers deployment observation and the data processing, product generation, and emergency response for the FY4-02 batch ground application system. This improves the high effectiveness, stability, and reliability of the unified command and scheduling of the normalised emergency response satelliteground system. The fully automatic FY-4B high-speed imager business system entered trial operation on 15 June 2022. Up until 20 October 2022, a total of 37 emergency responses have been completed with a success rate of 100% for satellite-ground measurement and control scheduling. While ensuring satellite safety, we achieved rapid deployment of payload emergency observation, with 950 regional observations within 24 hours and an average response time of no more than 30 minutes for the entire business process. This system effectively alleviates the pressure on satelliteground resources caused by frequent changes in observation tasks, ensures the coherence of remote sensing data, and plays an important data support role in flood season and various disaster meteorological support.
