LRGS stands for Local Readout Ground Station. LRGS is a universal store-and-forward device for GOES-DCP data. It can receive data via several satellite links and the internet. It stores the raw DCP data efficiently for a month or more, automatically deleting the oldest data when pre-set storage limits are reached. It provides the DDS network service to distribute data efficiently to client processes, such as DECODES.
The LRGS can retrieve data via any of the input interfaces as shown in diagram below. The LRGS can be configured with multiple interfaces. It can merge data simultaneously from any or all of the interfaces shown at the left. The LRGS acts as a store-and-forward device. It archives any amount of historical data (limited only by available disk space) and provides network interfaces to a variety of programs shown at the right.
