MightySat Ⅱ.1卫星的主要有效载荷中有一台傅里叶变换超光谱成像器,这是将要在空间飞行的这类传感器中的首台仪器。在过去的一年中,该传感器已通过初步设计阶段,传感器的一个工程样机已经制成。该样机已开始受到鉴定。到目前为止,传感器已达到其重量、体积和电源的设计目标。一种异乎寻常的高水平随机振动鉴定迫使人们重新设计两块反射镜的安装技术。一种定制的、适用于空间的VME电子摄像机接口和用以处理20M位组/秒图象数据的控制卡已经设计和制成,而且已同一组(4个)C-40处理器耦合以提供160 MIPS的星上处理能力。现正在研究任务的运行,利用卫星的在轨三轴操纵能力,仪器将演示 30 m的地面采样距离。根据预定计划,有效载荷应于1999年初交付以便在总线上的装配。
The main payload of the MightySat II.1 satellite has a Fourier transform hyperspectral imager, the first of its kind to be in space. In the past year, the sensor has passed the preliminary design phase and an engineering prototype of the sensor has been made. The prototype has begun to be identified. So far, sensors have reached their design goals of weight, volume and power. An unusually high level of random vibration qualification forced people to redesign the installation of two mirrors. A custom, space-compatible VME electronic camera interface and a control card for handling 20 Mbit / s of image data have been designed and fabricated and have been coupled to the same set of (four) C-40 processors 160 MIPS on-board processing power. Now working on the mission, using on-orbit three-axis maneuvering capability of the satellite, the instrument will demonstrate ground sampling distances of 30 m. According to a predetermined plan, the payload should be delivered in early 1999 for assembly on the bus.
