Spoofing signal detection is an essential process in GNSS anti-spoofing. The detection
probability of the existing metrics degrades significantly for many specific combinations of …

Security of global navigation satellite systems (GNSS) is important since the navigation
capability provided by the GNSS is a key enabler for many civilian and military applications …

Spoofing attacks are threatening the global navigation satellite system (GNSS). The
maximum likelihood estimation (MLE)-based positioning technique is a direct positioning …

This paper describes and demonstrates an assisted GPS technique, termed “Collective
Detection,” for combining satellite correlograms to enable rapid acquisition and direct …

In order to enhance the sensitivity of Global Positioning System receivers, increasing the
coherent integration time in the acquisition process is necessary. This letter analyzes the …

Passive localization is important because of its strong concealment and long detection
distance. Space-borne passive radiation source location technologies have contradicting …

This paper describes the improvements to acquisition that can be gained by combining
signals in terms of the theoretical reduction in C/N0 acquisition for given probability of false …

Since the development of the GPS, the global navigation satellite systems (GNSS) have
been widely diversified: maintenance, modernization and deployment of new systems such …

In order to enhance the positioning capability of terrestrial networks, a novel communication
and navigation fusion signal is proposed. The novel signal multiplexes the communication …

Mean acquisition time (MAT) is one of the key performance indicators for the acquisition of
global navigation satellite system (GNSS) signals. Usually, there are two stages in GNSS …
