Although GPS is one of the most important technologies of our age, it is surprisingly susceptible to tampering and failure. GPS signals are actually surprisingly weak with leaves them vulnerable to not only spoofing, but jamming.

In the United States, both jamming and spoofing are illegal, but other countries (which often use GPS as it was the first and arguably most reliable system) the laws vary and are sometimes nonexistent. This has led to many problems with GPS jamming and spoofing in other countries and here in the US. read more
