A system and method for communicating between ground stations and mobile satellites effectively eliminates the need for transferring information from one ground station to another. Communication between a ground station and a mobile satellite is accomplished via an intermediate network of geosynchronous control satellites. The mobile satellite is positioned within a three-dimensional cellular grid formed by the network of geosynchronous satellites. This system is particularly applicable to a terrestrial network communicatively coupled to the geosynchronous network via one or more ground stations. The terrestrial network of ground stations no longer needs to perform expensive, time-consuming and manual synchronization and hand-off procedures. Instead, the position of a ground station antenna can remain fixed on one specific satellite in the geosynchronous network, while the mobile satellite is tracked by the geosynchronous network utilizing the three-dimensional cellular grid formed by intermediate control satellites.
