Globally a fully functioning GPS constellation generates over $1B per day, the satellites in question are specifically the Block IIIF that have improvements over Block III, notably when it comes to M-Code which has huge anti jam implications.

Really the downside is we are now wanting to launch Block IIIF’s first, and disregard some already built III’s. Limited time as a stockpile option to replace older satellites after the IIIF’s as sitting in a warehouse is bad for the atomic clocks meant to be in space.

You’re close, but a couple of clarification points: We’re not going to launch IIIFs before the rest of the IIIs. At least no discussions to do so yet, but we have discussed pushing SVs 11 and 12 (the first two IIIFs) to launch right after SV10. The first two IIIFs are largely the same as the IIIs anyway. The primary constraining factor to our SVs on the ground is the shelf life of the batteries. It’s better now that we’ve switched to Li instead of NiH2, but still are a life cycle concern if they are in extended cold storage instead of regular charging/discharging as designed.

I thought we were putting up a IIIF in January ahead of the next III?

Nope. GPS III SV06 is scheduled to launch January 18th. The first IIIF doesn’t even start assembly until August 2023. We’re building the IIIF non-flight test bed now. SV11 (the first IIIF) will finish testing right around the same time GPS III SV10 is launching.

Does it finally cover all of the flavors, including mint?

Mint jelly will still be allowed, as jam is not jelly

And those are the type of loopholes that don't allow us to have nice things.

The raspberry harvests are all being used for pi productions.
