There are other technologies. GPS is an obvious one though it can be blocked. I think HIMARs used GPS with inertial backup if it's lost. Also with modern image recognition you can give the thing a picture of what it's supposed to hit for the last bit. I'm not sure which actual techs are used. Ukraine has a market set up where fighters can order the tech they need from defence startups. It's a significant advantage over Russia which has comparable tech but is bureaucratic and corrupt as to how it's allocated.

Some stuff from Google on FP-1 drones - the most popular long range one:

>Technological Features: They emphasize modularity, resilience to electronic warfare, and are developing optical navigation systems to reduce reliance on GPS.
