在致导激光仪的协助下，发射器可将带有卫星定位系统且外壳附有环氧黏着剂的迷你跟踪设备投射并牢牢黏附到目标车辆上，这样警方就可以在不危及公众安全的前提下对嫌犯车辆进行追踪。

With the help of a guiding laser, it shoots a satellite-based tracking device, smothered in epoxy goo, onto the target vehicle, allowing the police to track the suspect without endangering the public.

说句题外话，像“GPS”(即“全球定位系统”——译者注)这样的技术倒的确可以通过三角测量的卫星定位进行远程跟踪，比如说跟踪某个坐在车里的人。

As an aside, a technology such as GPS can in fact track a thing or, say a person in a vehicle, remotely from far away, by triangulating off of satellites.
