Abstract
A navigational apparatus and method for augmenting a GNSS signal to the GPS simulator with alternative position, navigation, or timing (PNT) data, wherein the GPS simulator encodes an RF-simulated GPS signal based on the alternative PNT data when the GNSS signal is not available or is denied. The alternative PNT data may be provided by one or more of an Inertial Measurement Unit, Inertial Navigation System (IMU/INS) module and oscillator coupled to the GPS simulator.
