美国休斯飞机公司正在考虑一项商业投资,打算研制一颗用来监视海洋的小卫星,卫星收集的数据拟出售给渔业和环境部门。计划研制的卫星叫作“海洋宽视场遥感器”(Sea Wi FS),卫星重约250磅,可望于1991年投入使用。卫星将在700公里高的太阳同步轨道运行,在中午时穿过赤道。商业Sea Wi FS卫星将携带多谱段仪器,遥感器观测幅宽为2800公里,它将在8个窄波段可见光和近红外谱段收集低分辨率数据。该卫星的数据将类似航宇局雨云-7卫星的海岸带彩色扫描仪数据。
The U.S. Hughes Aircraft Company is considering a commercial investment and plans to develop a small satellite to monitor the ocean. Data collected by the satellite are intended to be sold to the fisheries and environment department. The proposed satellite is called the Sea Wi FS, which weighs about 250 pounds and is expected to go live in 1991. The satellite will run on a 700-kilometer solar-synchronous orbit and cross the equator at noon. Commercial Sea Wi FS satellites will carry multi-band instruments with 2,800-km observations of the remote sensor, which will collect low-resolution data in eight narrow-band visible and near infrared bands. The satellite’s data will be similar to coastal color scanner data from NASA’s Nimbus-7 satellite.
