tailieunhanh - A gaussian mixture model based GNSS spoofing detector using double difference of carrier phase

In this paper, we propose a novel method to effectively detect GNSS (Global Navigation Satellite Systems) spoofing signals. Our approach utilizes mixtures of Gaussian distributions to model the Carrier Phase’s Double Difference (DD) produced by two separated receivers. DD calculation eliminates measurement errors such as ionosphere error, tropospheric error and clock bias. DD values contain the angle of arrival (AOA) information and a small amount of Gaussian noise. |
