Performance assessment of BeiDou-3 PPP-B2b real time pre-cise point positioning. [PDF]

Sci Rep
To assess the performance of the PPP-B2b service, most existing studies typically store real-time PPP-B2b messages and leverage them to acquire precise satellite orbits and clock offsets. However, they often overlook potential interferences, such as occlusions and receiving delays, that may occur in real-time scenarios. Consequently, these studies fail

Single-base station positioning for photovoltaic power plant inspection UAVs based on PPP-B2b signal. [PDF]

Sci Rep
Aiming at the situation where photovoltaic power stations in remote areas suffer from poor communication networks, which makes reliable acquisition of satellite precise orbit data and clock offset data unattainable, this paper employs PPP-B2b combined with broadcast ephemeris to obtain precise orbit and clock offset data.
