在光通信APT技术中，位置误差信号的提取是非常关键的一环，相应地探测器件的选择就显得至关重要。

But in the laser communication of APT technique, the position error signal's distill is very important, correspondingly, the choice of the detector seem to be to importance.

通过测量信号在卫星和天线之间传播所需的时间，汽车的位置可以被锁定在100米误差之内。

By measuring the time required for a signal to travel between the satellites and the antenna, the car's location can be pinned down within 100 meters.

结果显示，大部分工况下进气压力传感器和节气门位置传感器的信号重构误差可控制在10%以内，表明了所提出的调节策略是切实有效的。

The results show that the error of estimated value of both throttle position sensor and manifold pressure sensor are less than 10%, and the strategy put forward in this paper is valid.
