Processing of data from global navigation satellite systems (GNSS), such as GPS,
GLONASS and Galileo, can be considerably impeded by disturbances in the ionosphere …

Abstract The PRIDE Lab at GNSS Research Center of Wuhan University has developed an
open-source software for GPS precise point positioning ambiguity resolution (PPP-AR)(ie …

The Global Positioning System (GPS) is a navigation system based on satellite technology.
Its fundamental technique involves measuring the ranges between the receiver and a few …

We develop a new approach for cycle slip detection and repair under high ionospheric
activity using undifferenced dual-frequency GPS carrier phase observations. A forward and …

China completed a basic COMPASS navigation network with three Geostationary and three
