电场探测仪是卫星进行高精度电场探测的关键载荷，其传感器的空间布局对探测精度影响很大。文章对传感器空间布局的影响因素和分析方法进行了研究，并以轨道高度500km的太阳同步轨道卫星为例，结合卫星的实际任务运行，对虚假光电场控制、电场探测仪传感器的几何布局构型、传感器与卫星的相互遮挡和干涉关系进行了分析，并最终优化确定了传感器的空间布局。研究结果表明，优化的传感器空间布局可以在设计阶段就针对多种误差，有效地提高其探测精度。

Space borne electric field detector (EFD) is a key instrument to detect in-situ electric field within ionosphere, and the sensor layout for EFD is one of the most important factors which would affect electric field data accuracy. In the paper, the influence of sensor layout is studied as well as the relevant analysis method. To demonstrate the whole procedure, a satellite in 500kin sun-synchronous orbit is used as an example for analyzing the factors such as sunward offset field, geometric layout and shading effects etc. , which concludes an optimized sensor layout. The analysis result shows that several error sources could be avoided through detailed analysis and op timized on EFD sensor layout, which can improve the EFD performance at design stage.
