The constellation of BeiDou Navigation Satellite System (BDS) is different from that of GPS. GPS constellation includes only Medium Earth Orbit (MEO) satellites, while BDS constellation is composed of three types

Przemysław Mazureks become a reality based on the real-time precise point pointing (RT-PPP) technique. The accuracy of zenith total delay (ZTD) and PWV derived from RT-PPP have been validated using observed global positioning system (GPS) data and meteorology data from Satellite Positioning Reference Station Network

First, satellite positions were calculated based on the experiment of simulation of dynamics and orbital evolution. Secondly, the computational model of dynamic pointing of anten
