Abstract
A low-cost, low maintenance earth-based station is disclosed which includes a fixed aperture antenna directed to a fixed location. The system operates with a plurality of non-geosynchronous satellites that will periodically pass through a beam coverage region of the antenna. When one of the satellites comes within range of the earth-based station, the earth-based station detects the presence of the satellite and synchronizes the earth-based station with the satellite. When synchronization is complete, the earth-based station transmits stored data to the satellite. The data to be transmitted is stored within a data storage device that may be present at the earth-based station or remotely located and transmitted to the earth-based station using conventional techniques. The data may be transferred to the earth-based station from a remote data storage facility in response to a polling request after the satellite has been detected within range of the antenna, or automatically transferred from the remote storage facility and temporarily stored at the earth-based station in anticipation of the next satellite to come within range.
