Marines Use ASTi Radio-Over-IP Bridges to Integrate Live and Virtual Training Assets

December 9, 2014

Advanced Simulation Technology inc. (ASTi) announced that the U.S. Marine Corps has fielded five Voisus radio-over-IP communications systems at the Marine Corps Air Ground Combat Center (MCAGCC) at Twentynine Palms, CA and at the 1st Marine Expeditionary Force (I MEF) at Camp Pendleton, CA. System installation, interoperability testing, and new equipment training was accomplished in two days, after which the I MEF determined that the Voisus system was ready to support their training requirements.

The Voisus communications systems installed at these locations boast the following capabilities:

  • Seamless linking of Marine Corps air and ground radio communications with simulator-based training facilities for blended live-synthetic training
  • Conservation of live radio usage; exercise staff and military trainees use Voisus Client apps on their computers and tablets for common access to live radio assets through network connections
  • Clients that provide trainees and exercise staff with group intercoms, private point-to-point calling, conferencing, and text chat
  • Web-enabled scenario generation and centralized system management from any network point, using ordinary web browsers

The Voisus systems' inaugural use was during Large Scale Exercise 2014 (LSE14), a Marine Expeditionary Brigade combat exercise based at Twentynine Palms. The exercise involved 3,700 U.S. Marines and Canadian soldiers executing long-range raids, casualty evacuations, live-fire events, defensive operations, and close-air support.

ASTi systems provided critical services and linked live and virtual voice comms between geographically distant sites, including:

  • Twentynine Palms: Battle Sim Center, Combined Arms Command and Control Training Upgrade System (CACCTUS), MAGTF Tactical Warfare Simulation (MTWS)
  • MCAS Miramar: MV-22 and CH-53 Flight Simulators
  • MCAS Yuma: AV-8B Flight Simulator
  • Camp Pendleton: H-1 Flight Simulators
  • Camp Wilson: Direct Air Support Center, Tactical Air Operations Center, Combat Convoy Simulators
