L96 Multiple constellation output

I have enabled GPS+GLOSNASS+Galileo constellations. In the L96 GNSS Protocol Specification document, Table 3 shows that the Talker ID for GGA and VTG is “GP”. Does this mean that the information in the GGA and VTG sentences are from GPS constellation only? Or is the information from all constellations?

Hi arurke
The information in the GGA and VTG sentences is from all the constellations in the combined constellations. Talker ID is a historical issue and you can ignore it.

Thank you very much George!
