I have a question of that sort. A couple of days ago I've found a GPS tracker under my car. If I use the GPS jamming equipment, then I will be tracked?
First of all you should know that GPS is not the only option to calculate somebody's location. Those tracking device may use GLONASS as well, it is a Russian analogue of GPS. The only difference is that they use different frequencies and a simple GPS jammer won;t be able to block it. Also, cell tower triangulation may be used. That technique is used to track your raw location between three closest GSM base stations.
