The NeTTS Tools


The Realistic Operational Communications Scenarios (ROCS) System

ROCS POC: Joshua Davis

ROCs Overview ROCS, the NeTTS father, was developed in the late 1990s under contract to the Marine Corp Operational Test and Evaluation Agency (MCOTEA) using Resource Enhancement Program (REP) funding. ROCS supports the test and evaluation of IP-based data communication systems and networks. ROCS can inject and record:

ROCS 4.0 integrates the ROCS message capabilities into the NeTTS architecture, allowing ROCS to be used in conjunction with VETT in a fully-coordinated test involving data, voice, and video messages.

VETT Overview

Auxiliary Tools

ROCS system includes supplementary COTS tools that can be used to augment the basic functions of a ROCS test, providing enhanced functionality.

Prior and Scheduled Uses

The ROCS System has been used, or is scheduled to be used, to support the evaluation of several United States Marine Corp programs. ROCS supports the entire spectrum of system evaluation, including developmental tests, operational assessments, and operational tests.

The Voice/Video Emulation Test Tool (VETT)

VETT POC: Michael Witten

VETTOngoing C4I architecture modernization efforts are resulting in an increasing level and complexity of load on tactical networks, and a merging of the traditionally separated voice, video, and data communications channels. New and highly complex, multi-faceted systems will routinely utilize, generate, transfer, and manage both voice and video information on the battlefield, some of which must be exported from the front lines to Continental United States (CONUS) command and control and/or analysis facilities.

To support the testing of such systems, GTRI developed VETT in 2005 under contract to Marine Corps Operational Test and Evaluation Activity (MCOTEA) and the U.S. Army Operational Test Command (USAOTC), using funds provided by the Resource Enhancement Program (REP). VETT interfaces include:

VETT and ROCS can be used together to provide fully coordinated tests involving voice, video, and data messaging systems.

Scheduled Uses

The Commanders Air Defence Environment Test Tool (CADETT)

CADETT POC: Fred Wright

CADETT Graphic CADETT is a stand-alone system built for the U.S. Navy COMPOTEVFOR (Commander Operational Test & Evaluation Force) in 2003 to support the testing of advanced air defense systems. CADETT adds sensor and track simulation components to the NeTTS family, allowing one to generate a realistic, imperfect air picture. Built upon the Satellite Toolkit (STK), CADETT offers impressive 2D and 3D graphics.


CADETT supports the following communication interfaces:

Prior and Scheduled Uses

CADETT has been used in support of the Deployable Command and Control Testing (DJC2) system test (spiral 1) and the MDA’s Multiple Hypothesis Correlator integration.

The Integrated Broadcast Service (IBS)Test and Analysis System (ITAS)

ITAS POC: Andrew Henshaw

ITAS was developed in 2004 for support of the IBS Combined Test Force (CTF) Spiral 2 Developmental and Operational test program. ITAS provides a capability to inject and record the message traffic at the required density and ITAS duration necessary to evaluate the performance of the IBS, comprised of the Information Management Element (IME) and distribution network. Generated messages from ITAS are injected into the IBS via the IME. ITAS records messages output from the IME and at receiving Tactical Data Processor (TDP) locations. The ITAS-generated message traffic consists of pre-recorded intelligence messages that are formatted into message sets designed to test a specific capability of the IBS. ITAS emulates intelligence feeds into IBS, facilitates measurements to evaluate system performance, and provides real-time monitoring/control and rapid data reduction capabilities.

The ITAS supports the following data formats for the IBS:

Prior and Scheduled Uses

ITAS was developed to support developmental test and evaluation of various components of the IBS. The primary focus of ITAS is to evaluate the network servers associated with the IBS. The tests that ITAS has supported in the past and those planned to be supported in the future include the following:
