Effect of lunar gravity models on Chang'E-2 orbit determination using VLBI tracking data
The precise orbit determination of Chang'E-2 is the most important issue for successful mission and scientific applications, while the lunar gravity field model with big uncertainties has large effect on Chang'E-2 orbit determination.

Evaluation of strategies for the ultra-rapid orbit prediction of BDS GEO satellites
The quality of BeiDou Navigation Satellite System (BDS) Geostationary Earth Orbit (GEO) ultra-rapid products is unsatisfactory because GEO satellites are nearly stationary relative to ground stations.

Impact of Thermospheric Mass Density on the Orbit Prediction of LEO Satellites
Many thermospheric mass density (TMD) variations have been recognized in observations and physical simulations; however, their impact on the low‐Earth‐orbit satellites has not been fully evaluated.

Towards robust aero-thermodynamic predictions for re-usable single-stage to orbit vehicles [PDF]
Re-usable single stage to orbit launch vehicles promise to reduce the cost of access to space, but their success will be particularly reliant on accurate and robust modelling of their aero-thermodynamic characteristics.

Orbit Predictions for Space Object Tracked by Ground-Based Optical and SLR Stations
In many cases, we have few optical observations over a short time span, and most of the information generated is too limited to compute a full orbit according to the angles-only method.
