Interference multipath is an important factor to affect the anti-jamming performance for the
global navigation satellite system (GNSS) antenna array receiver. However, interference …

Thanks to the international GNSS service (IGS), which has provided an open-access real-
time service (RTS) since 2013, real-time precise point positioning (RT-PPP) has become a …

Adaptive filtering algorithms can be used on the time-domain processing of navigation
receivers to suppress interference and maintain the navigation and positioning function. The …

Thanks to the international GNSS service (IGS), which has provided multi-GNSS precise
products, multi-GNSS precise point positioning (PPP) time and frequency transfer has of …

GNSSs, such as Galileo and modernized GPS, BeiDou and GLONASS systems, offer new
potential and challenges in precise time and frequency transfer using multi-frequency …

The global satellite navigation system represented by global position systems (GPS) has
been widely used in civil and military fields, and has become an important cornerstone of …

The dual-frequency precise point positioning (DF-PPP) technique has been widely used for
time transfer. Actually, DF GNSS receivers are much more expensive than single-frequency …

The precise point positioning (PPP) technique is widely used in time and frequency
applications. Because of the real-time service (RTS) project of the International GNSS …

Abstract In 2012 the Center for Orbit Determination in Europe (CODE) joined the Multi-GNSS-
EXtension project (MGEX) of the International GNSS Service (IGS). Since the end of 2013 …

The information of the satellite clock switching and performance variations on-orbit of
Chinese BeiDou-2 Navigation System (BDS) is not available for the public. In order to detect …
