Cooperative GNSS authentication
from Inside GNSS
Secure, reliable position and time information is indispensable for many civil GNSS applications such as guiding aircraft, tracking freight, synchronizing power grids and cellular networks and time-stamping financial transactions. This article introduces a cooperative signal authentication architecture in which civil GNSS signals, as well as the encrypted military signals on the same frequency, are sampled by a user receiver and several ad-hoc cross-check receivers at the same time.
