The core performance elements of global navigation satellite system include availability,
continuity, integrity and accuracy, all of which are particularly important for the developing …

As the Global Navigation Satellite System (GNSS) is widely used in all walks of life, the
signal structure of satellite navigation is open, and the vulnerability to spoofing attacks is …

Within the framework of differential augmentation, this paper introduces the basic technical
framework and performance of the BeiDou Global Navigation Satellite System (BDS-3) …

Communication, positioning, navigation, and decision-making abilities have evolved into
Positioning, Navigation, and Timing (PNT) intelligence during the long process of human …

China's BDS Navigation Satellite System (BDS) has been independently developed, which
is similar in principle to global positioning system (GPS) and compatible with other global …

To realize the smooth transition from regional BeiDou Navigation Satellite System (BDS-2)
to the global one (BDS-3), the integration of BDS-2 and BDS-3 is important for providing …

Abstract BeiDou Global Navigation Satellite System (BDS-3) not only performs the normal
