The German Space Operations Center (GSOC) of DLR routinely performs precise orbit determination (POD) for it's low earth orbit missions. The requirements for many current and future missions require ...
It can be seen that under this special condition, the discrete- time state equation is still conditionally linear so that there is no need to use multistep propagation any more. Therefore, MUKF will ...
Precise Point Positioning (PPP) is widely used for high-accuracy navigation, but broadcast ephemeris from the BDS-3 system still suffers from hourly discontinuities that degrade real-time performance.
