GSGT provides equivalent functionality to the existing HCS SIM system. GSGT generates radar, non-radar, and combined radar/non-radar tapes for use by the National Airspace System (NAS) as a source of real time inputs and facilitates the testing and integration of NAS and related subsystems. It enables simulation (SIM) developers to perform their development activities in a fraction of the time that it would normally take utilizing NAS SIM alone.

SGET is one of the ERAM CSCIs. SGET is based on a set of core functions provided by the GSGT CAS product. GSGT has been augmented with a set of external functions to enable interfacing with other ERAM CSCIs.

From the SGET SRS: The SGET CSCI provides the functions to create, store, retrieve, edit and preview Scenarios. SGET is used by Scenario Developers. SGET provides a set of tools that assist in the generation of Scenario inputs and Scenario debugging. In addition, SGET's preview function and output reports allow a user to see and analyze Scenarios in the off-line environment. This allows a high degree of Scenario checkout before execution in a lab or system environment.

GSGT includes a special build tailored to running with ERAM Evaluation System. This GSGT build includes most of the functionality found in normal version of GSGT, with exception of several features designed for better integration of the system.
