This anti gps tracker disrupter will knock out gps logging or gps tracking system which may be operating on your vehicle, using our GPS disrupter system will make it very hard for any one to keep tabs on you or your vehicle, most spy devices can be quickly installed to a vehicle and allow the users to track your every move by mapping software or a gps recording system, this unit will disable the gps link and render the spy device useless.

这个反全球定位系统跟踪干扰，将淘汰的GPS伐木或GPS跟踪系统，可能就是操作上你的车，用我们的GPS干扰系统，将使它很难任何人以掌握你或你的车辆，大部分间谍装置，可迅速安装了一部汽车上，并让用户能够追踪你的一举一动，由绘图软件或全球定位系统记录系统，这个单位将禁用全球定位系统连接，并提供间谍装置形同虚设。

Let be a homeomorphism, the following statements were obtained: if is distal and has POTP ,then does not have the average shadowing property; if is equicontinuous and has the average shadowing property, then f is minimal; let :X→X be distal and chaintransitive, then does not have POTP; is distal if and only if is distal.

设是个同胚映射，得到了如下结果：若有POTP且是distal的，则不具有平均跟踪性；若有平均跟踪性且是等度连续的，则是极小的；若是distal的且是链可迁的，则不具有POTP；是distal的当且仅当是distal的。
