Ironically best fit for replacement is Starlink constellation.
IMHO after seeing what Ukraine pulled off in Russia recently - un-jammable gnss is kinda dangerous until drones like Skydio trickle down to the masses.

I’m now realizing I know hardly anything about GPS. Like it was made in the 50’s or something? Do we keep sending more GPS satellites into space? Or are there just the original handful?
The DMSP program was discontinued in 2015 by a vote in congress[1]. Virtually every working stallelite in this program has failed. As best as I can tell there's just a single working one specifically NOAA-19[2].
Instead the program has switched to JPSS[3] which is part of GEOSS[4].

Is this an attempt at controlling the narrative around climate change, in line with the impacts at NOAA and other climate-related government agencies?

I see 3 possibilities: They're cutting it off to limit bad news about climate change, for political reasons. Or they're trying to set up some private company to sell the same data. Or (tinfoil hat on) they're going to do something the raw microwave data might expose and so they're trying to keep the microwave data secret.

Yes. Quoting Proj ct 2 25: > Break Up NOAA ... NOAA consists of six main offices ... Together, these form a colossal operation that has become one of the main drivers of the climate change alarm industry and, as such, is harmful to future U.S. prosperity. This industry’s mission emphasis on prediction and management seems designed around the fatal conceit of planning for the unplannable. That is not to say NOAA is us…

Is that possible? I thought GPS works by just listening for signals from GPS satellites? I’m now realizing I know hardly anything about GPS. Like it was made in the 50’s or something? Do we keep sending more GPS satellites into space? Or are there just the original handful?
Earlier quoted context omitted.
By all means please do and pay for it yourselves.
Heaven forbid the richest nation on earth that steals resources from everyone else contribute to global improvement.

There's a 4th possibility: This program was cancelled in 2015 and it finally ended. The replacement is https://en.wikipedia.org/wiki/Joint_Polar_Satellite_System
