最近,在研制美国海军海洋观测卫星(N-ROSS)的竞争中,洛克希德导弹和空间公司披露了其海军海洋观测卫星的方案建议。洛克希德公司提供的 N-ROSS 卫星设计方案是,卫星设计寿命为三年,重1800公斤左右。预计,1990年9月由大力神Ⅱ运载火箭置入高度为820公里、倾角99度的太阳同步轨道。在该轨道上,N-ROSS卫星能够每36小时绘制一次海洋环境图。N-ROSS 将携带四种遥感器:一个新型的低频微波辐射计、一个美国航宇局研制的散射计和海军
More recently, Lockheed missiles and space companies disclosed proposals for naval ocean observation satellites in the race to develop the Navy’s N-ROSS satellite. Lockheed company to provide N-ROSS satellite design is that the satellite design life of three years, weighing about 1800 kg. It is estimated that the synchrotron orbit at a height of 820 kilometers and an inclination of 99 degrees will be placed by the Hercules II carrier rocket in September 1990. On this orbit, N-ROSS satellites are capable of drawing a marine environment map every 36 hours. N-ROSS will carry four types of remote sensors: a new low-frequency microwave radiometer, a NASA-developed scatterometer and the Navy
