Our current design is capable of just over 1 year of continuous propulsive operation. Feel free to mess with our services tool on the website to simulate various missions to see how many operations a single droid could perform! But to answer your question, yes, several orbital inclinations are highly populated with operational satellites and debris. A mission such as going from 55° inclination to polar would be possible but very expensive (ie would likely drain a significant amount of life out of the Droid on a single mission). This is why we want to build a constellation of vehicles spread across many inclinations.
