Real-time PPP algorithm considering hourly discontinuous BDS-3 broadcast ephemeris with covariance-adaptive Kalman filter

open access: yesSatellite Navigation
Previous studies indicate that the accuracy of the BDS-3 broadcast orbit is comparable to that of the real-time precise products provided by International GNSS Service (IGS). However, the precision of both the broadcast orbit and clock remains limited by

Calculation of a Dynamical Substitute for the Real Earth–Moon System Based on Hamiltonian Analysis

open access: yesThe Astrophysical Journal
The Earth–Moon libration points no longer exhibit the dynamical characteristics of “equilibrium points” due to perturbation effects when applying the ephemeris model. By decoupling the forced motions within the ephemeris model and computing the dynamical
