Workshop 2017 - Lars Prange - The Center for Orbit Determination in Europe (CODE) is contributing to the IGS MGEX (Multi-GNSS Extension) since its start in 2012 with an orbit and clock solution - meanwhile fully incorporated in the operational activities for the IGS. The CODE MGEX (COM) solution currently includes the satellite systems GPS, GLONASS, Galileo, BeiDou, and QZSS. Due to its experimental character, the COM solution is subject to frequent changes and improvements. Subsequently, we focus on empirical solar radiation pressure models suited for orbit normal attitude, which is applied to QZSS and BeiDou satellites at low elevations of the Sun above the respective orbital planes. We discuss results obtained with different force decompositions. The publication of meta data of the Galileo ...
