,Durchführung und Auswertung von Messungen,rrors based on real observations which collected from multi-GNSS experiment (MGEX) stations. The accuracy of BDS/GPS real-time clock errors was also analyzed which compared with the final precise clock products. Finally, the performance of BDS/GPS RT-PPP with the real-time BDS/GPS satellite clock er

Gallenblasen- und Gallenwegskarzinom,ecision. The orbit precision of GEO and IGSO is improved more than that of MEO. The precision of BeiDou satellite orbit can improve by extending the orbit arc with certain limits, and the result is mostly obvious in the tangential direction.

To mitigate integration errors during eclipses, this contribution introduces an improved method based on Runge-Kutta9 integrator. We use dichotomy to detect the exact epoch of penumbra
