When simulating a signal that includes GLONASS and Galileo my receiver is reporting different satellite IDs than shown in the Signal Studio, why?

While GPS satellites are commonly identified by the pseudorandom codes (PRN) that they use, there is no industry standard yet for how to refer to the GLONASS or Galileo satellites. Therefore, each GNSS chipset vendor may use a different label for a particular satellite. For example, in the u-Center software for u-blox chipsets, the u-Center Galileo SV ID is equal to the N7609B SV ID minus 6, and SV IDs of 205 to 210 in the u-Center software correspond to SV IDs of E1 to E6 in the N7609B.
