Inversion of the Ionospheric Current Density by Multi-point Synchronous Magnetic Field Measurements

  • 摘要: 相对于传统的单点磁场探测,多点磁场协同探测可以同时获得各测点磁场,消除探测磁场随时间的变化,能更好地计算空间电流密度.根据由多点磁场反演计算空间电流密度的计算方法,开展数值仿真,分析卫星编队数量、卫星编队构型、卫星定位偏差、卫星姿态测量误差、磁场测量误差、外部磁场强度及外部电流密度等对电流反演误差的影响.仿真结果表明,5星编队优于4星编队.在5星编队条件下,卫星姿态测量误差、卫星编队构型和外部磁场强度是反演误差的主要来源.根据仿真结果,当卫星姿态误差为0.001°,卫星编队尺度约为100km时,赤道区域电流密度的反演相对误差约为24%.
