A GPS replacement doesn’t mean having to launch a new GPS constellation.

As stated there are Lready 3 GPS MEO networks in the sky; plus various LEO constellations - Iridium is one already being leveraged for accurate navigation services - and other s are being launched in their thousands; SpaxeX alone intends to launch about 20,000 by 2025.

As as long as you know we’re they are then all you need is a smart received with a chip based atomic clock. Consider it a 21st century form of celestial navigation - and it can’t be jammed......
