It's a movable observation platform, plain and simple.
People forget that satellites orbit and course corrections like remaining on station are not designed into there plans and doing so uses up the
precious maneuvering fuel they need to have as there orbit naturally decays over time.
With the X37, when it needs more fuel - it lands and refuels.
