Mobile Network To Support Afghan Mission
As the U.S. mission in Afghanistan evolves from full spectrum combat operations to a support role in helping Afghan forces take hold of their countrys security, unit commanders emphasize the need for network mobility.
Warfighter Information Network-Tactical, or WIN-T, Increment 2, the Armys improved tactical network communications backbone, was designed to fulfill such a mission.
As we reduce our presence in Afghanistan, it is absolutely critical that we continue to understand what is happening around us, to understand the operational environment, said Col. Sam Whitehurst, commander of the 3rd Brigade Combat Team, 10th Mountain Division (Light Infantry), during a recent training exercise at Fort Drum, in preparation for his units possible deployment to Afghanistan. My ability to take the information that I am hearing from my team leaders, and then share it with all of our Afghan partners, so they can correspondingly help confirm or deny that information and share what they are seeing, is one of the most critical elements as we go forward into Afghanistan over the next year.
The mobile WIN-T Increment 2 network is being fielded as part of the Armys new capability sets. Capability Set 13, or CS 13, is the first of these fully-integrated fielding efforts, which are scalable and tailorable in design to support the changing requirements of current and future missions. CS 13 includes radios, satellite systems, software applications, smartphone-like devices and other network components that provide connectivity from the stationary command post to the commander on-the-move to the dismounted Soldier. WIN-T Increment 2 is the tactical communications network backbone that binds the capability sets together.
The Army began fielding CS 13 in October 2012 to 3rd BCT, 10th Mountain Division, which is based at Fort Drum, and to the 4th BCT, 10th Mountain Division, at Fort Polk, Louisiana. The two units are training with these advanced capabilities and preparing for possible deployment to Afghanistan with them later this year. The 101st Airborne Division (Air Assault) Headquarters has already been fielded with WIN-T Increment 2 elements, and two BCTs from the 101st are slated for full CS 13 fielding later this year.
If called upon to deploy, Army BCTs armed with CS 13 capabilities will serve as Security Forces Advisory and Assist Teams, or SFAATs, who will work with Afghan National Security Forces to improve their capability and help the Afghans secure their country as coalition forces reduce their presence. The coalition forces footprint continues to decrease and many of the forward operating bases and fixed sites used to access the network are being dismantled.
As U.S. forces take down their fixed infrastructure and become more dispersed and mobile in conducting these support operations, they will rely on WIN-T Increment 2 for critical reach-back communications.
If you take a look at what were doing in Afghanistan right now, as U.S. forces start to reduce their presence, were still partnered with the Afghan National Security Forces and continue to focus on their development, but were doing it over greater distances, Whitehurst said. We are distributed throughout the area on a much greater scale than we were before.
Having the capability to command and control the brigade on-the-move gives commanders the ability to extend their reach even as the Army reduces its presence. It will enable them to focus on the mission of developing the Afghan Security Forces, Whitehurst said.
WIN-T Increment 1, formerly known as the Joint Network Node-Network, began fielding in 2004 and provides Soldiers with high-speed, high-capacity voice, data and video communications down to battalion level units, at-the-quick-halt. It utilizes both satellite and line-of-sight capability for optimum network connectivity and bandwidth efficiency. WIN-T Increment 2 improves upon these technologies by providing Soldiers with an integrated network, which for the first time, provides mobility and reaches down to the company level. It further increases capability by introducing network radios to the architecture and enhancing Network Operations, a suite of integrated monitoring tools used by communications officers to command and control the network.
When it comes to combating the communication challenges created by Afghanistans harsh and expansive terrain, WIN-T Increment 2 provides an advantage over previous capability. It enables communication signals to better reach over mountains and across deserts, said Capt. Jesse Ellis, commander of C company, 3rd Brigade Special Troops Battalion.
As SFAAT missions evolve, Soldiers will no longer be tied to fixed U.S. bases and secure network infrastructure, so maintaining communications through WIN-T Increment 2 while assisting the Afghans is a tremendous capability to bring to the effort, said Maj. Graham Wood, brigade communications officer for 3rd BCT, 10th Mountain Division

GPS III Tests Are Successful
A Lockheed Martin-led industry team has completed successful functional integration tests of the spacecraft bus and network communications equipment on the first satellite of the next generation Global Positioning System, known as GPS III.
The recent testing of GPS III space vehicle 1 (SV 1) busthe portion of the space vehicle that carries mission payloads and hosts them in orbitassured that all bus subsystems are functioning normally and ready for final integration with the satellites navigation payload.
Systems tested included: guidance, navigation and control; command and data handling; on-board computer and flight software; environmental controls; and electrical power regulation.
The SV 1 satellites network communication equipment subsystem that interfaces with the ground control segment and distributes data throughout the space vehicle also passed all tests as expected.
This milestone follows Februarys successful initial power-on of SV 1, which demonstrated the electrical-mechanical integration, validated the satellites interfaces and led the way for functional and hardware-software integration testing. The successful completion of the SV 1 bus functional check out validates that the spacecraft is now ready to begin the next sequence of payload integration and environmental testing, prior to delivery, said Keoki Jackson, vice president of Lockheed Martins Navigation Systems mission area.
GPS III SV 1s navigation payload, which is being produced by ITT Exelis, will be delivered to Lockheed Martins GPS Processing Facility (GPF) near Denver later in 2013. The hosted nuclear detection system payload has already been delivered and mechanically integrated. The satellite remains on schedule for flight-ready delivery to the U.S. Air Force in 2014.
GPS III is a critically important program for the Air Force, affordably replacing aging GPS satellites in orbit, while improving capability to meet the evolving demands of military, commercial and civilian users. GPS III satellites will deliver three times better accuracy and, in order to outpace growing global threats that could disrupt GPS service, up to eight times improved anti-jamming signal power for additional resiliency.
The GPS III will also include enhancements adding to the spacecrafts design life and a new civil signal designed to be interoperable with international global navigation satellite systems.
Lockheed Martin is currently under contract for production of the first four GPS III satellites (SV 1-4), and has received advanced procurement funding for long-lead components for the fifth, sixth, seventh and eighth satellites (SV 5-8).
The GPS III team is led by the Global Positioning Systems Directorate at the U.S. Air Force Space and Missile Systems Center. Lockheed Martin is the GPS III prime contractor with teammates ITT Exelis, General Dynamics, Infinity Systems Engineering, Honeywell, ATK and other subcontractors. Air Force Space Commands 2nd Space Operations Squadron (2SOPS), based at Schriever Air Force Base, Colorado, manages and operates the GPS constellation for civil and military users.
