摘要
描述了FY-3A气象卫星紫外臭氧垂直探测仪的组成和4种主要工作模式,即大气测量模式、太阳连续测量模式、太阳分立测量模式及标准灯测量模式。在此基础上对在轨运行的任务进行了分析说明。针对仪器运行参数多、测量模式转换复杂等特点,提出了合理的在轨运行控制方案,介绍了其程控设计要点与实现。给出了FY-3A星紫外臭氧垂直探测仪在轨测量的太阳模式和大气模式紫外辐射遥感数据,其太阳分立模式波长重复性为±0.03 nm,自动增益转换功能使系统的动态范围达到106量级。实验结果表明,FY-3A星紫外臭氧垂直探测仪在轨工作正常,测量模式转换和执行准确,其运控方案完备,数据获取有效,仪器在轨工作处于最佳性能状态。
Abstract
A satellite borne Solar Backscatter Ultraviolet Spectrometer (SBUS) developed by our country has been put into operation in-orbit for the first time. This paper introduces the composition of the SBUS and gives its main working modes(atmospherical mode, solar modes and standard lamp mode). After analysis of run missions, a reasonable scheme of operation control in-orbit is presented according to the characteristics of various operation parameters and complicated mode transitions, and then the main points of software design is explained in detail. The remote sensing data of ultraviolet radiation measured in-orbit with the solar/atmospheric working modes are given, which shows that the wavelength reproducibility by the discrete solar mode is ±0.03 nm and the dynamic range of the system reaches 106 magnitude with the function of automatic gain control. Obtained results demonstrate that the proposed measurement modes have been implemented correctly and the scheme of operation control is completed. The SBUS are working in a best state with reasonable paremeters and optimum performance.
