Critical government and industry sectors (such as law enforcement, transportation,
communication, and finance) are growing increasingly dependent on Global Navigation …

The paper presents an approach for detection of spoofing/meaconing signals using the
direction-of-arrival (DOA) measurements available in a multi-antenna navigation receiver …

Array processing proved itself in the last decades as a powerful approach to suppress
harmful radio frequency interference. However, the interference mitigation in the spatial …

A nonplanar circularly polarized dual-band antenna for global navigation satellite system is
presented. The shape of the antenna is conformal to the surface of a cylinder such that the …

The positioning and timing services provided by global satellite navigation systems (GNSSs)
to the users are strongly affected by possible perturbations of the navigation signals in the …

The paper presents several novel techniques for detection of spoofing/meaconing signals
using the direction-of-arrival (DOA) measurements available in a multi-antenna navigation …

Adaptive antenna array processing is widely known to provide significant anti-interference
capabilities within a Global Navigation Satellite Systems (GNSS) receiver. A main challenge …

The quality of the ranging data provided by a global navigation satellite systems (GNSS)
receiver largely depends on the synchronization error, that is, on the accuracy of the …

A multimode antenna (MMA) can be an interesting alternative to a conventional phased
antenna array for direction-of-arrival (DoA) estimation. By MMA, we mean a single physical …

This letter discusses the design and manufacturing of a miniaturized 2× 2 stacked patch
antenna array, operating at E5a and E1 Galileo bands (ie, at central frequencies of 1176 …
