Orbit Combination of BeiDou Satellites with Pseudo-stochastic Pulseecision. 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.

Mitigation of Orbit Integration Errors for Eclipsing Satellitesngs less error during eclipsing season than Runge-Kutta4 and Adams integrators, and can change step size flexibly. 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

Characteristic Analysis and Short-Term Prediction of GPS/BDS Satellite Clock Correctionn length, which is compared with the prediction using Polynomial and Periodic method. The results show that the precision has significantly improved, the mostly GPS rubidium clock error prediction precision of 6 h is better than 0.6 ns and 1 h is better than 0.25 ns which has 50 % improved as statis
