Drones exist, and cost a lot less then thousands to buy. Plus a drone can be used when you want to, the satellite goes overhead every few weeks and if it is a cloudy day too bad. For farms the information from images is only valuable on a few specifc days, too early and you don't learn anything, a few days later and it is too late to do anything about it.
