The more impressive military stuff are the SAR based satellites and the capabilities of the newer remote sensing satellites. I don't think much of the rumours suggesting newer Chinese satellites have some submarine detecting LIDAR or laser technologies but the exciting synthetic aperture radars probably have immense military value. China has been busy launching SAR and other remote sensing satellites since the early 2000s.
I've honestly no doubt satellites are key to PLA's detection and tracking of USN surface and possibly even subsurface assets. They may even play some important role in directing AShBMs. To have some redundancies the tech that doesn't demand perfectly smooth and predictable distance measuring, may be relying on the various super high altitude drones in PLA. The US will definitely be targeting all Chinese satellites in case of kinetic war. I'm not sure if any are in unreachable geo orbits.
