Abstract EN
A perceived emerging threat to GNSS receivers is posed by a spoofing transmitter that emulates authentic signals but with randomized code phase and Doppler over a small range.
Such spoofing signals can result in large navigational solution errors that are passed onto the unsuspecting user with potentially dire consequences.
In this paper, a simple and readily implementable processing rule based on CNR estimates of the correlation peaks of the despread GNSS signals is developed expressly for reducing the effectiveness of such a spoofer threat.
Consequently, a comprehensive statistical analysis is given to evaluate the effectiveness of the proposed technique in various LOS and NLOS environments.
It is demonstrated that the proposed receiver processing is highly effective in both line-of-sight and multipath propagation conditions.
