It can add the ability to see aircraft. For example, the Hudson Bay area of Canada was non-radar. No radar was being installed because it is so expensive to install maintain, especially in a remote area like that. But, when relatively cheap non-moving receiver antennas can be installed with lower maintenance costs, it becomes viable. Now there is radar equivalent in the Hudson Bay area for properly equipped aircraft.
