Working together toward a common vision, Army partners recently came together to collaborate on critical Army positioning, navigation and timing, or PNT, initiatives, technologies and capabilities necessary to support integrated system development.

The Vehicular Integration for C4ISR/EW Interoperability, known as VICTORY, Standards Support Office, or VSSO, risk reduction demonstration, held in January at Aberdeen Proving Ground, Maryland, focused on completing risk reduction efforts associated with implementing VICTORY capable systems on ground vehicle platforms.

The VSSO successfully demonstrated three major capability areas: Remote control and management of devices including PNT/GPS, data radios, and electronic warfare, or EW; distributed position and timing via native implementation on tactical radio and via adapter functionality for legacy radios; and Information Assurance (IA) — demonstrating centralized access control capability using VICTORY compliant software.

The demonstration focused on distributed position and timing, remote control, and centralized access control using VICTORY capabilities on essential items found in a vast majority of Army vehicles such as Global Positioning Systems, or GPS, tactical radios and EW devices. Charged with augmenting and enhancing GPS to provide more reliable PNT for the Army, the Direct Reporting Program Manager Positioning, Navigation & Timing, or PM PNT, protects the Soldier, and the equipment they use in the battlefield, through the development and fielding of advanced PNT technologies. As part of its strategy, PM PNT works closely with a number of partners across the Army and Department of Defense to ensure the most accurate and trusted PNT available to the Soldier.

Multiple partnerships

The VSSO risk reduction demonstration involved partners from across the Army, including Program Executive Office Ground Combat Systems, PEO GCS; PEO Combat Support & Combat Service Support, or PEO CS &CSS; PEO Command Control Communications – Tactical, known as PEO C3T; PEO Intelligence, Electronic Warfare & Sensors, or PEO IEW&S; Tank and Automotive Research, Development and Engineering Center, TARDEC; Vehicle Electronics and Architecture, or VEA; and the Communications-Electronics Research, Development and Engineering Center, CERDEC, Command Power and Integration PNT Division.

“Building optimal PNT capabilities for the Soldier is no easy task,” said Kevin Coggins, program manager for PM PNT. “Our partnerships play a critical role in making the Army PNT strategy a success and drive continuous innovation to provide the Warfighter with PNT data that they can trust.”

VICTORY is a set of open standard specifications that promotes inter-operability between Command, Control, Communications, Computers, Intelligence, Surveillance and Reconnaissance, or C4ISR, and EW systems through the use of standardized on-the-wire messaging and interfaces. This systems engineering approach reduces the overall integration time and cost, allows resources and data to be shared, reduces the size, weight and power, or SWaP, demand and total life cycle cost and management complexity for the ground vehicle platforms. A benefit of VICTORY is the use of common software pieces, which can be implemented and reused by developers as they adopt VICTORY in their own systems.

Coupling standards

Today, C4ISR/EW systems are integrated on ground vehicle platforms primarily utilizing serial connections like point-to-point, which are complicated. Modification to one system usually requires modifications to all other systems that are integrated with it. In addition, each system brings its own unique hardware resources, and in most cases, duplicate GPS receiver, monitor, keyboards, and antennas/cables associated with it. Data are not generally shared effectively among these stove-piped bolt-on systems.

Coupling VICTORY standards and concepts enables improved interoperability, flexibility and consolidation.

“VICTORY has been a collaborative effort for years among many PEOs, including PEO C3T,” said Deputy PEO for C3T Mary Woods. “Platform integration is a major challenge for the Army, and VICTORY should help enable us to mitigate that challenge in the future.”

VICTORY has adopted the commercial standard Precision Time Protocol version 2 as one of the VICTORY standards. As a widely accepted commercial standard there are many off-the-shelf hardware and software implementations available for reuse, thus negating the need for custom, proprietary timing solutions. The goal of the risk reduction demonstration was to share common data within a vehicle in an easier, more flexible and adaptable form using VICTORY compliant mechanisms.

Software defined tactical radios are critical to Soldiers working in highly challenging environments. Tactical communications provide Soldiers the capability to exchange voice, data and video even when spread over large geographic areas. Accurate timing is required for radios to synchronize and form tactical communication networks quickly. In collaboration with the CERDEC CP&I PNT lab, one capability the VSSO demonstrated was distributing time from a single PNT source simultaneously to two different types of tactical radios, establishing a continued connection and the Soldiers’ ability to communicate with one another.

Remote operations

Another focus of the demonstration was remote control and monitoring of C4 and EW devices. Remote control using standard VICTORY messaging enables Army vehicle operators to monitor and configure their onboard systems from a single, common display rather than having to reach for or access each device individually. VICTORY enabled device control also enables the Army vehicle community to consider relocating devices within the vehicle to reduce cab clutter and enhance safety through improved egress while still providing ready operator access.

The remote operation was focused on common operator tasks such as changing volume and presets on tactical radios, monitoring status of onboard GPS systems and monitoring and controlling the status of a Counter Remote Controlled Improvised Explosive Device (RCIED) Electronic Warfare (CREW) device (Duke v3).

Risk reduction

The final focus of the demonstration was a centralized access control function using the VICTORY Access Control Software, or VACS. Access to the radio and GPS configuration was controlled by VACS using authentication and authorization functions. Soldier or machine-to-machine actions were first authenticated and then checked for authorization. Valid and invalid authorization scenarios were demonstrated. This demonstration successfully established centralized access control functionality, which can be integrated into a larger, overall security strategy and architecture. As with other capabilities demonstrated, the VACS software is available for reuse.

The VICTORY risk reduction demonstration proved that a PTP switch has the ability to successfully send data to a number of systems on the network at once. Thorough testing was conducted confirming that providing PNT as a shared service would not degrade subscriber system capability. As a result, the Army has a clear path to access easier system interoperability and integration and accomplish SWaP reduction across vehicle platforms.
