太空中单个卫星之间是通过光信号进行通讯的。因此需要一个可以自动调节角度的镜面倾斜系统，以确保一个卫星发出的光信号能够正对且持续稳定地达到另外一个卫星的接收系统。为了实现对镜面倾斜角度的闭环控制，核心的问题是通过非接触位移传感器准确测量镜面角度。为此目的，米铱公司提供高精度电涡流传感器系统，小巧的外形尺寸使该传感器可以方便地集成到整个系统当中。

In the communication between individual satellites fast mirror tilting systems are employed which use laser light as the carrier medium. The application of these mirrors enables the laser beam of the optical transmitter to be exactly aligned on the receiver and the direction to be kept stable during the transmission. The core of the closed-loop control system for the mirror tilting systems are displacement sensors which determine the exact positional values via the mirror movement. For this application MICRO-EPSILON supplies extremely high resolution eddy current systems in miniature versions which are integrated into the overall system.
