Russia has laser-guided weapons, which have been around for decades. GPS-guided artillery and rockets are relatively new. According to Wikipedia, they were developed because laser-guidance turned out to be too cumbersome in Afghanistan, where the Taliban might be too well concealed or too far away for convenient laser targeting. Perhaps drones and fancier features (e.g. top attack flight modes) make laser guidance more effective than before (presuming the Russian versions can benefit from such technologies), but M982 GPS-guided shells have a range of 25+ miles, and HIMARS GPS-guided rockets 50+ miles (up to 120), which provide huge advantages in distance in addition to not needing a laser designator on the target the entire time.
