U.S. Navy Combined Arms Virtual Environment (CAVE) immersive simulator

The U.S. Navy is using MetaVR visuals in its Combined Arms Virtual Environment (CAVE) training dome and desktop systems. The CAVE training system provides an immersive, large field-of-view partial dome display for sea-and land-based individual and team training in supporting arms and close air support.

This spring, MetaVR's business partner Battlespace Simulations (BSI) delivered to and installed the latest CAVE system at the Expeditionary Warfare Training Group Pacific (EWTGPAC) in San Diego, CA.

The CAVE is comprised of student desktop stations in the partial dome, an instructor/operator station (IOS), a role-player station, and a supporting arms station in an adjoining classroom.

Ten VRSG channels are used in the CAVE to provide out-the-window (OTW) views for the partial dome, instructor station, and role player station, supporting arms station, as well as views for UAV camera feed and emulated military equipment (EME) devices. The CAVE also uses MetaVR's geospecific 3D terrain, and model libraries.

The system uses BSI's MACE as the CGF/SAF, BSI's Viper DIS radio for an operationally realistic communications environment, DIScord for AAR and debrief, Open Street Map server, combat radio interface, and several BSI-designed EME devices: emulated military equipment (EME) devices to include a portable lightweight designator/rangefinder (PLDR), Vector 21
binocular laser rangefinder, and an IZLID infrared illuminator.

Earlier in 2017, BSI delivered and installed the CAVE system to the Expeditionary Warfare Training Group Atlantic (EWTGANT) in Virginia Beach, VA. These systems replace legacy Multi-Purpose Supporting Arms Training (MSAT) dome systems at these sites.

The first U.S. Navy site to adopt the CAVE system was the Joint Close Air Support (JCAS) branch at the Naval Aviation Warfighting Development Center (NAWDC) at Naval Air Station (NAS) Fallon, NV. NAWDC JCAS uses the CAVE for the simulation training portion of the JTAC qualification course for all Naval Special Warfare (SEAL) JTAC students.

U.S. Air Force Joint Terminal Control Training and Rehearsal System (JTC TRS)

In early 2016 MetaVR was chosen as the 3D real-time visualization provider in the award of the Joint Terminal Control Training and Rehearsal System (JTC TRS) contract to QuantaDyn Corporation by Department of the U.S. Air Force – Air Force Material Command. This award supersedes a limited contract for the JTC TRS program that the U.S. Air Force awarded to Fidelity Technologies in February 2009.

This partial dome simulator, which uses MetaVR visual channels, geospecific 3D terrain, and culture and entity models, immerses the joint terminal attack controller (JTAC) or forward air controller (FAC) trainee in a 3D real-time virtual battlefield. These close air support simulators can be connected to the U.S. Air Force A-10 Full Mission Trainers (FMT) which are already standardized on MetaVR 3D visuals.

QuantaDyn's JTC TRS solution under contract is comprised of commercial off-the-shelf (COTS) components including QuantaDyn's DIScover, Immersive Display Solutions' immersive dome display system, Battlespace Simulations' (BSI's) MACE, and MetaVR's VRSG, which provides the out-the-window and sensor visuals for the dome display, a ROVER device, and emulated military equipment.

Under the contract, QuantaDyn initially installed two JTC TRS devices in 2016, and three more in 2017, with additional options for a total of 30 devices. The first delivery milestone was met in June 2016, with successful completion of USAF site acceptance testing at Fort Benning, GA, the site of the first JTC TRS installation.

JTAC desktop simulators in SOTACC classrooms at Yuma Proving Ground

MetaVR VRSG, 3D terrain, and 3D content are in the desktop JTAC simulators that replaced the former call for fire trainer (CFFT) simulators at the Special Operations Terminal Attack Controller Course (SOTACC) as part of an award made in late 2015 by Special Operations Command to Battlespace Simulations (BSI). The two-classroom setup uses 24 VRSG channels in total coupled with BSI's Modern Air Combat Environment (MACE) software.

One of the two classrooms of JTAC desktop simulators at the SOTACC facility at the U.S. Army Yuma Proving Ground, Yuma, Arizona.

Each station contains a communications suite on a tablet to simulate PRC-117, PRC-148, PRC-152 radios, and a ROVER feed. All new hardware, including two terrain servers loaded with MetaVR's 3D terrain and 3D content were delivered to the SOTACC facility at the U.S. Army Yuma Proving Ground, Yuma, Arizona, in December 2015. The desktop JTAC simulators replaced the CFFT simulators delivered several years ago by Fidelity Technologies.

AAJTS / AJTS dome simulators at Nellis JTAC Schoolhouse, Hurlburt Field, and other sites

The Advanced Joint Terminal Attack Controller Training System (AAJTS,or AJTS at non-Air National Guard sites) is a 5-meter, 270 degree FOV training dome system which fully immerses the JTAC trainee in a 3D real-time virtual battlefield. The system, a combined effort of QuantaDyn, USAF Trainer Development Division, Battlespace Simulations (BSI), Immersive Display Solutions (IDSI), and MetaVR is comprised of, in part, components provided by BSI (MACE as the CGF/SAF at the instructor operator station and pilot/role-player station), IDSI (5-meter dome with14-channel LED+IR projection system, audio system, and warp/blend) MetaVR (VRSG, geospecific terrain, and models), and ASTi (voice communication and sounds). The system also includes emulated military equipment.

The partial dome simulator is designed to support all JTAC and combat controller squadron level continuation, qualification, and mission rehearsal training. The training system is designed to meet the requirements for unit training at Air Support Operations Squadrons (ASOS) and Special Tactics Squadrons (STS) and is accredited for types 1, 2, 3 controls for both day and night, and for laser target designation with a simulated military laser device by the US Joint Fire Support Executive Steering Committee (JFS ESC) Memorandum of Agreement (MOA) and the NATO Standardization Agreement (STANAG); the system meets or exceeds current STANAG standards.

iCASS JTAC Trainer at UK JTAC Schoolhouse

MetaVR's business partner Close Air Solutions uses VRSG in its Immersive Close Air Support Simulator (iCASS) training system. Since 2015, the iCASS has been in use in the UK’s FAC/JTAC Training Programme, at the Joint Forward Air Control Training and Standardisation Unit (JFACTSU), Royal Air Force Station Leeming, North Yorkshire, England.

The iCASS system is a FAC/JTAC simulation system which provides a high-fidelity, immersive training environment with a full after action review (AAR) capability. The system meets DIS/SISO standards. This system, developed by MetaVR's business partner Close Air Solutions, features a 3 meter 240 x 120 degree FOV immersive dome display from Immersive Display Group and uses MetaVR visuals: 12 VRSG channels for the projected views and simulated laser target designator and range finder, and 3D content. The iCASS also features computer generated/semi-automated forces and threat generation from MetaVR's business partner BSI's MACE, which includes CFF, 9-Line, and 5-Line interfaces as well as the virtual pilot station. The iCASS also uses BSI's Viper DIS radio for communications and DIScord DIS recorder for after action review (AAR).

The iCASS has been accredited by the US Joint Fires Support Executive Steering Committee (JFS ESC) Memorandum of Agreement (MOA) and NATO AIRCOM (STANAG 3797) to replace up to 8 out of 12 live controls required annually by each qualified FAC/JTAC.

JTAC desktop simulation system

Since 2013, 32 Air Force Special Operations Command (AFSOC), Air Combat Command (ACC), and Air Support Operations Squadron (ASOS) JTAC training sites in the US and abroad took delivery and installation of MetaVR and BSI’s JTAC desktop simulation system. These systems include 10 AFSOC JTAC Simulators (AJS), 20 JTAC/TACP-Operational Simulation Suites (J/T-OSS 2.0) used by Air Combat Command (ACC), a desktop system at the 169th ASOS in Peoria (ANG) and a desktop system at Camp Murray, WA (ANG).

These installations followed the accreditation in 2012 of MetaVR and BSI’s JTAC simulation system granted by the Joint Fire Support Executive Steering Committee for JTAC training. The system is accredited for types 1, 2, 3 for both day and night, and for laser target designation with simulated military laser, in accordance with the JTAC Memorandum of Agreement. Type 1 accreditation requires either a head-mounted display (HMD) or a 220+ degree FOV dome display. The JFS ESC accreditation applies to any JTAC simulator that uses VRSG version 5.7 or greater and BSI MACE version 1.0 or greater, such as the AFSOC JTAC trainer, USAF J-T/OSS, AAJTS, JFIRES, and JTAC-TRS prototype systems.

The accreditation followed a demonstration to members of the Joint Fire Support Executive Steering Committee (JFS ESC) at Hurlburt Field, FL, on May 24, 2012. Initial consideration for this accreditation resulted from a competitive fly-off at Hurlburt Field in August 2011, in which the BSI and MetaVR joint system was ranked the highest among five competing simulation systems in meeting the requirements for JTAC simulators.

This JTAC simulator is comprised of BSI's MACE scenario/entity generator and MetaVR’s VRSG. The system also includes an integrated software based Distributed Interactive Simulation (DIS) radio, a recording capability for recording and AAR/playback of missions, and a simulated laser range finder/laser designator. The BSI/MetaVR JTAC simulation system, a privately funded COTS solution, enables users to perform training missions on a virtual battlefield with close air support interfaces such as 9-Line, 5-Line, and Call for Fire.

Features that support training missions include physics-based weapons performance, laser target designation, full-motion infrared video feeds, a mission editor, human-level behaviors, path finding, blast effects calculations, complex weather system control, and a robust weapons and entity library. The JTAC system is capable of importing existing military topographic database information to allow operators and instructors to quickly develop scenarios appropriate for mission rehearsal.

This joint effort JTAC simulator is offered as a commercial-off-the-shelf (COTS) firm fixed price simulator with publicly available pricing, and is available in portable and desktop configurations with a head-mounted display, and as an integrated system with a fully immersive dome

The BSI/MetaVR system has been fully integrated at several sites, including multiple AFSOC sites such as Special Tactics Training at Hurlburt Field, FL, the Michigan Air National Guard's 4-meter Joint Fires Dome in Grayling, MI, McChord-Lewis Joint Base, Ft. Benning, Pope AFB, Cannon AFB, Kadena Air Base, Japan, Milden Hall RAF, UK and AFRL's JTAC-TRS 5-meter domes, and is currently being developed for additional US and international customers. Several other sites use the simulator through the U.S. Air Combat Command (ACC) under which the system is called the JTAC-TACP/Operational Simulation Suite (J-T/OSS) are listed below.

The US Air Combat Command (ACC) is fielding MetaVR visuals in J-T/OSS, which is used at the US Air Force’s Distributed Mission Operations Center (DMOC) at Kirtland Air Force Base (AFB) and other sites across the US. Note that VRSG's simulated UAV-produced ROVER feed for the J-T/OSS is through the Air Force Synthetic Environment for Reconnaissance and Surveillance (AFSERS). This system has been chosen by the ACC as the interim solution for the Joint Terminal Controller Training Rehearsal System (JTAC TRS).  J-T/OSS version 2.0 (which includes the accredited MetaVR/BSI JTAC simulator) will be the Interim Distributed Mission Operational (DMO) capable trainer until the JTAC TRS is fielded.

In addition to the DMOC at Kirtland AFB , the J-T/OSS is used for training at multiple sites across the US, including Nellis AFB JTAC Schoolhouse, Joint Base McChord-Lewis, Ft. Hood, Pope, Ft. Carson, Ft. Campbell, Ft. Riley, Scholfield Barracks HI, Ft. Drum, Ft. Benning, Ft. Polk, and Joint Base Elmendorf-Richardson, AK. *

Air National Guard

Air National Guard JTACs initially adopted the use of VRSG for training several years ago when they first developed their own desktop close air support training simulators with MetaVR VRSG in 2009. Trainees used VRSG in a first person shooter mode with a gamepad as the navigation device.

This service-developed Air National Guard JTAC simulator helped provide the basis for the ACC to approve MetaVR VRSG for use in simulated JTAC training. With this approval, issued in 2009, the training hours JTACs spend using VRSG contribute to approved simulator training credits for terminal attack control requirements.

Using subject matter experts, the DTOC develops and maintains a series of training scenarios that create simulated threats on the network for the Air National Guard sites. It also creates a Multiple Unified Simulation Environment/Air Force Synthetic Environment for Reconnaissance and Surveillance (MUSE/AFSERS) simulated UAV camera video feed that the Air National Guard uses to jointly simulate a close air support mission on geospecific terrain that correlates across both facilities' simulation applications. The JTAC simulations are fully interoperable with the A-10 Full Mission Trainers, F-16 Air National Guard simulators, the MUSE/AFSERS program, and the Army National Guard UAV trainers, as well as others.

MetaVR's Afghanistan virtual terrain, shown in several images on this page, is optimized for ground attack training missions in JTAC simulation, such as A-10 missions.

Approximately 30 ASOS sites in the US and overseas use VRSG for JTAC training in first person shooter JTAC mode and via a regeneration station. Networked environments that do not have the bandwidth to handle VRSG’s streaming MPEG (simulated UAV camera video feed) directly set up a UAV regeneration station to capture the streaming MPEG of the VRSG-simulated UAV camera payload video in the form of data packets. These data packets are then regenerated as video, and streamed to another device on a local network, such as a ROVER.

JFIRES at Grayling Air Gunnery Range

The Michigan Air National Guard’s Combat Readiness Training Center (CRTC) at the Grayling Air Gunnery Range in Alpena, MI, uses the accredited MetaVR/BSI JTAC solution in its JTAC simulation training system, called the Grayling 4m JFIRES Dome.

Used in conjunction with the Human Effectiveness Directorate studies on JTAC simulator training, the Grayling JFIRES dome is comprised of a 4-meter dome with 4 MetaVR VRSG channels, an installed BSI MACE instructor operator station, a MACE person-in-the-loop pilot station with 1 VRSG channel dedicated to out-the-cockpit views and another VRSG channel for the sensor view. The dome has a 4-meter spherical screen, which gives a JTAC trainee a 160° to 170° horizontal field of view. The JTAC trainee also has two additional VRSG channels available for a monocular/binocular used for laser range finding and target designation as well as a full motion video ROVER-type feed for external targeting information. The simulator has a variety of DIS tools, including DIS radios and a DIS recorder. The instructor can control all constructive entities (including attacking aircraft and artillery), as well as ground entities and threats.


The Air Force Research Laboratory (AFRL) Warfighter Readiness Research Division, 711th Human Performance Wing, at Wright Patterson Air Force Base uses VRSG in its JTAC training research in three JTAC dome training systems. These three systems, called Joint Terminal Attack Controller Training Rehearsal System (JTAC TRS), were developed and installed in 2007 at the AFRL site in Mesa, AZ, and then moved to Wright-Patterson AFB in 2012. The simulators are the precursors to the next generation JTAC dome training systems currently fielded or in production today. The dome systems provide AFRL with the testbed capability to continue the research and development for training in all facets of CAS and joint fires.

The JTAC TRS system provides a high-fidelity, fully immersive, realistic training and rehearsal environment with real-time sensor, simulator, and database correlation. Its primary focus is to provide a persistent total air-ground virtual training environment for networked air/ground training and mission rehearsals. This prototype system is used to train both JTAC and combat air crews assigned to accomplish complex missions in close proximity to ground forces. The JTAC TRS connects to distributed mission operations networks to enable geographically separated high-fidelity close air support platforms and JTAC and CCT teams to train together. Additionally, the JTAC TRS enables operators to conduct Joint Close Air Support (JCAS) training and mission rehearsal using tailored, dynamic scenarios that are relevant to mission tasking.

With information such as the laser code, the target location, and the compass rose, this view is the same view as seen in the desktop-based JTAC simulator. The desktop and dome simulators produce the same designator view. Click the image to see an enlarged version.

The JTAC TRS simulator built by Lockheed Martin, uses 19 VRSG channels, 14 of which are for the dome itself. There are 7 VRSG channels for 360-degrees around the bottom half of the dome, and another 7 channels for the top half of the dome. The remaining VRSG channels are used for various emulated hand-held command and control (C2) devices inside the dome (binoculars, laser range finders, and so on), a sound channel, and a single AAR/stealth channel. The DIS/HLA compliant system interoperates with legacy systems and provides the capability to network with other air and ground simulators, including simulators of the A-10 program.
