在低地球轨道上以掩星的几何形状观测全球定位系统，为电离层成像提供了一种强有力的手段。利用奇异值分解分析对空间和地面的电离层层析成像进行了研究。研究了分辨率和协方差矩阵，并进行了模拟，结果表明空间数据在解析水平和垂直结构方面明显比地面数据更有效。结果表明，掩星数据可以探测狭窄的垂直结构，如E层。(C) 1994 John Wiley and Sons, Inc。
Observing the Global Positioning System with a satellite in low earth orbit in an occulting geometry provides a powerful means of imaging the ionosphere. Tomographic imaging of the ionosphere from space and ground is examined using singular value decomposition analysis. The resolution and covariance matrices are examined, and simulations are performed that indicate that space data are significantly more effective than ground data in resolving both horizontal and vertical structures. It is shown that narrow vertical structures, such as the E layer, can be probed with occultation data. (C) 1994 John Wiley and Sons, Inc.
