Triple-frequency GNSS has been intensively studying in the past decades, especially with
the open service of China's BeiDou system. In this review, we will address the ambiguity …

Precise point positioning (PPP) has been suffering from slow convergences to ambiguity-
fixed solutions. It is expected that this situation can be relieved or even resolved using triple …

PPP-RTK which takes full advantages of both Real-Time Kinematic (RTK) and Precise Point
Positioning (PPP), is able to provide centimeter-level positioning accuracy with rapid integer …

To meet the demands of precise orbit and clock determination, high-precision positioning,
and navigation applications, a software called GREAT (GNSS+ Research, Application and …

Precise point positioning (PPP) is receiving increasing interest due to its cost-effectiveness,
global coverage and high accuracy. However, its application in the urban environment is still …

Along with the rapid development of GNSS, not only BeiDou, but also Galileo, and the newly
launched GPS satellites can provide signals on three frequencies at present. To fully take …

This paper focuses on the contribution of the global positioning system (GPS) and BeiDou
navigation satellite system (BDS) observations to precise point positioning (PPP) ambiguity …

Multi-constellation GNSS (multi-GNSS) and multi-frequency signals open new prospects for
fast ambiguity resolution (AR) of precise point positioning (PPP). Currently, all the BDS and …
