GPS is the foundation for commercial operations
GPS timing is used and considered essential in 15 of the essential Critical Infrastructure and Key Resources defined by Department of Homeland Security. According to the US government, attacks on these sectors, whether targeting one particular sector or a mix of them, could have a disastrous impact on national public health and safety, as well as security. Additionally, Fleet & Maritime operators, and autonomous vehicles rely on the acquisition of the weak GPS satellite signals to determine their precise location.
Unprotected GPS devices are susceptible to harmful jamming attacks that have catastrophic consequences.
