For some applications that's not that much. Imagine SpaceX putting one of these in each StarLink satellite and providing their own GPS-like service.
I'm not sure if this clock would be good enough for GPS. It's 3 orders of magnitude less accurate than a cesium clock. But with so many StarLink sats overhead, and synchronizing with more accurate ground clocks, might make up for that.
