Galileo L13 (GSAT0226 & GSAT0232)...Galileo L13 launch is planned for Sept. 13th 2024 from Cape Canaveral/Florida.
pre-launch testing for a commercial payload on Mission Galileo L13. Tests involve RF shielding ground system equipment attenuation stand-alone check at the SpaceX Payload Processing Facility at CCSFS
Given the previous Galileo launch expended the booster (B1060), I have a strong feeling another booster will be expended for this launch too.

To this date, the Galileo constellation has 30 First Generation satellites in orbit and an additional eight are ready to be launched, two in September this year and six more starting in 2025. Second Generation launches will begin before the end of this decade.
If I were to guess, a launch vehicle change.

That's performance penalty from the fuel reserves after MECO.

I was using logic based on the GPS-III launches when the first launch expended the booster and inserted the satellite into an elliptical orbit with the perigee at 1,200 kilometers. When SpaceX began recovering the booster starting with GPS-III 3, the perigee was 800 kilometers lower (400 kilometers).

When SpaceX began recovering the booster starting with GPS-III 3, the perigee was 800 kilometers lower (400 kilometers).GPS-3 has an apogee propulsion system, Galileo does not have one, so this is not an option here.
