Can a GPS jamming device disable the PT200?
The way a GPS jammer works is to emit energy at the frequency it is trying to block to raise the noise floor above the signal you are trying to receive, thereby making the signal unintelligible. The quality of a GPS jammer is based on how wide a frequency it can disturb and how much power it can emit–in effect, how far it can jam signals. The GPS jammer that thieves would be likely to use is small, and probably has only 5 meters of effective range. To understand how a GPS jammer would affect the PT200, we must take a look at how the PT200 works. The PT200 has two modes of operation: Assisted GPS and cellphone tower triangulation, both of which use different frequencies. Assisted GPS is less suseptible to jamming than GPS, and cellphone tower triangulation is even less susceptible than Assisted GPS to jamming. To give a specific example, a GPS jammer that can only jam a GPS signal at 5 meters would have to be within 2 meters to jam an Assisted GPS signal, and directly on top of a devic
