BRDM00DLR: DLR’s merged multi-GNSS broadcast ephemeris product
As contribution to the IGS multi-GNSS pilot project (MGEX), the German Space Operations Center (GSOC) of the German Aerospace Center (DLR) provides a merged GPS, GLONASS, Galileo, BeiDou, QZSS, IRNSS, and SBAS broadcast ephemeris product called BRDM00DLR. Input data are obtained from altogether 37 globally distributed stations of the IGS and CONGO networks. The input data are the same as for the BRD400DLR product but only the information supported by the RINEX 3 format is included in the BRDM00DLR product.
