TLS Model 2000系统定位原理是当被干扰卫星受到干扰时，我们可在与其轨道位置邻近的卫星中选择一颗类型相同的卫星，选择的邻星不是唯一的，选择时需注意的几个关键因素将在后面介绍。由于干扰源必定有一定的旁瓣泄漏，所以干扰信号的一部分能量会被发射到这颗相邻的卫星上去。我们可以用监测站的两副天线分别接收这两个来自两颗卫星转发的信号，并将接收到的信号传送到定位系统中去。
The TDOA-based source localization problem in sensor networks is considered with sensor node location uncertainty. A total least squares (TLSs) algorithm is developed by a linear closed-form solution for this problem, and the uncertainty of the senso
