The TAGS performs the spacecraft data capture and command uplink functions, allowing simplex or duplex communications.
TAGS can store command loads and all telemetry data for later delivery.
The TAGS receives satellite downlinked telemetry, performs basic decommutation operations, and transmits spacecraft health and safety data in real-time to the GNCC during spacecraft passes. The standard mode of high volume payload data delivery is on tape by a commercial carrier. Higher priority or lesser quantities of data can be delivered via Satcom or land lines to the customer. Prior to spacecraft or launch vehicle supports, each TAGS receives pointing, activation, and configuration instructions from the GNCC through a configuration database. Also through a secure Internet link enabled shortly before a pass, customers will be able to monitor the ground station configuration and availability from their own operations center.
