Not positive, but I believe that current base stations point at one satellite at a time, and will lose connection for a brief moment while they transition from one satellite to another. In the future, ground stations will be able to lock on multiple satellites at a time, in order to bond channels for higher bandwidth, and also to do handoffs so there's no drop in connectivity.
