The Long Lead Parts Procurement Starts
The GPS III program will affordably replace aging GPS satellites while improving capability to meet the evolving demands of military, commercial and civilian users. GPS III satellites will deliver better accuracy and improved anti-jamming power while enhancing the spacecraft?s design life and adding a new civil signal designed to be interoperable with international global navigation satellite systems.
Incorporating lessons learned from previous GPS programs, the Air Force initiated a ?back-to-basics? acquisition approach for GPS III. The strategy emphasizes early investments in rigorous systems engineering, industry-leading parts standards, and the development of a full-size GPS III satellite prototype to significantly reduce risk, improve production predictability, increase mission assurance and lower overall program costs. These investments early in the GPS III program are designed to prevent the types of engineering issues discovered on other programs late in the manufacturing process or even on orbit.

Defending CENTCOM Critical MILSATCOM Links
More than 22,000 miles away, spinning silently through the vacuum of space, is one of the most critical components to air, space and cyberspace superiority today; a satellite.
?We have five priority missions we support,? said Capt. Brandon Davenport, the Space Cell chief. ?Theater missile warning, personnel recovery support, satellite communications, GPS constellation health and modeling, as well as battle space characterization.?
One of the biggest threats to satellite communications and GPS missions is its vulnerability to electromagnetic interference, or EMI, which causes the signal to be ?jammed.?
Jamming, at its most basic level, is denying a satellite the ability to communicate by overwhelming it with energy where it would expect to see the friendly signal. This is basically like someone using a bullhorn to drown out someone else?s conversation.
This type of occurrence can be intentional, in which case it is considered hostile, or accidental. The most common causes of accidental EMI are easily found and remedied. Hostile jamming, however, can require a more creative solution.
?To assure minimal operational impact, our communicators systematically work through actions to quickly restore the services affected.? said Lt. Col. Jason Knight, the Director of Space Force?s assigned space weapons officer. ?If the EMI is determined to be intentional, we engage up the chain and through other governmental agencies to apply non-lethal, or lethal, national instruments of power in order to quickly restore services and resolve the problem.?
EMI resolution would not be possible without cross-Combatant Command and cross-agency collaboration between space and cyber professionals, or one of the most technical aspects of the space cell?s mission, geolocation of a hostile jamming signal.
?Our focus is to track down a jamming signal with high-confidence and say ?it?s this guy?,? Knight said. ?By combining our cyber and space expertise at the operational and tactical levels we are better able to attribute and identify sources of interference, and eliminate intentional denial of SATCOM by our adversaries.?
This allows for overlap between several satellites and grants U.S. forces the flexibility to shift to another satellite if necessary to complete the mission.
The linchpin in this whole process is Operation Silent Sentry, run by the 379th Expeditionary Operations Squadron. The Silent Sentry team?s mission is to monitor hundreds of satellite transmissions every week using the Rapid Attack Identification Detection Reporting System and help detect and locate signals that do not belong on U.S. satellites, such as a jammer.
?The Silent Sentry antennas and our satellites represent two known locations and the jammer a third, unknown location,? Davenport said. ?Because we start knowing two out of three points, and have both frequency and time values available to us, we can use algebra to figure out a line running north south as well as a line running east and west of possible locations. Where those lines cross, we?ll find the offending transmitter.?
Though the technology does not yet exist to prevent jamming, the available actions that the U.S. military and its allies may take can be swift and decisive.
?Most emitters that put our systems at risk can be identified by our teams,? Davenport said. ?During combat, an adversary could technically jam our satellite signals, but we can recover fairly quickly, attribute the source of interference and respond accordingly.?

SATCOM Terminal Training Suite Upgraded
The Army recently began schoolhouse computer-based and simulated training upgrades for its advanced Secure Mobile Anti-Jam Reliable Tactical -- Terminal to evolve the previous legacy training system to accommodate various new system enhancements.
This system makes it possible for Soldiers to extend the range of their network in such a manner that communications cannot be jammed, detected or intercepted. The Advanced Extremely High Frequency, or AEHF, SMART-Ts provide advanced capability to the force over legacy systems, including a four-fold increase in throughput and enhanced security features.
?Since all of the legacy SMART-T systems are currently being upgraded to the AEHF capability, these training upgrades are a vital step in ensuring that Soldiers and their units are getting the most out of these improved protected communication capabilities, and in the most efficient and cost-effective manner available,? said Lt. Col. Greg Coile, product manager for Satellite Communications, or PdM SATCOM, which manages SMART-T. PdM SATCOM is assigned to the Army?s Project Manager Warfighter Information Network-Tactical.
The United States Army Signal School and Fort Gordon, Georgia, training upgrades began in December 2012 after months of planning and scheduling critical events.
Major enhancements include the AEHF upgrades to the Satellite Simulator, or SATSIM, and Computer Based Training, or CBT, system, along with the addition of 12 new AEHF SMART-T systems, with the last of these systems being delivered in February.
The updated training began in mid-January with four Army classes and one Marine class, totaling 73 students. Over the next year, the three-week AEHF SMART-T course will be taught to 62 classes, with more than 1,000 Army students and 100 Air Force, Marines and civilians.
?These training enhancements increase efficiencies for both the Army and Marine Corps,? said Larry Raville, SMART-T project lead. ?If these Soldiers have an AEHF SMART-T fielded to their unit, they will have already had the Advanced EHF training, eliminating the need for delta training had they only been trained on the legacy system.?
SMART-T is part of the WIN-T architecture and is compatible with both WIN-T Increment 1 and Increment 2, which make up the Army?s tactical communications network backbone.
Similar to a home Internet connection, WIN-T Increment 1 provides high-speed, high-capacity voice, data and video communications to units on the battlefield, at-the-halt or at-the-quick-halt.
WIN-T Increment 2 provides this network to maneuver formations down to the company level while on the move. In May WIN-T Increment 2 will undergo its Follow-on Operational Test and Evaluation at Fort Bliss, Texas, and White Sands Missile Range, New Mexico. As part of the training improvements at Fort Gordon, the facility?s SATSIM was upgraded to accommodate the new AEHF SMART-T training.
The SATSIM provides constant simulated satellite access to allow training to be conducted year-round, without interruption or overloading the satellite in real-time.
Satellite time is a limited and costly resource. However, the simulator provides the same training benefits and replicates everything that Soldiers would normally see if they were logged onto a real satellite, thus decreasing satellite cost and dependency.
?Simulation is a big focus now because our forces can train in real-time without having to utilize valuable satellite resources,? said Mel Pointer, SMART-T logistics management specialist. ?Now instead of Soldiers logging on to the actual satellite for training, they can use the SATSIM, and that satellite resource can be more appropriately dedicated to an operational unit where it is most needed.?
The SMART-T CBT system was also upgraded to accommodate the AEHF capabilities. The CBT replicates a satellite and AEHF SMART-T working in tandem so Soldiers receive real-time, simulated training as if they were actually using the system.
In the past this server-based system was used to provide classroom training on the legacy SMART-T, but in January both the server and CBT classrooms were upgraded to accommodate the upgraded AEHF version of the system.
The number of classrooms and student capacity was also increased to four classrooms with 24 students per class, running two or three shifts.
Although it is not practical or cost efficient to have enough actual live AEHF SMART-Ts to put every Soldier on a terminal for hands-on experience for the entirety of the course, the SATSIM and CBT upgrades maximize the amount of training that can be conducted by minimizing the amount of hands-on training time needed.
Following the classroom training with the SATSIM and CBT, the SMART-T AEHF terminals themselves provide hands-on training through live practical exercises.
Since the Soldiers already had the simulated training, by the time they get to the hands-on training, they know how to operate the system.
?By having this updated SMART-T AEHF training available, Fort Gordon, the Training and Doctrine Command, and the Army are postured to absorb any type of Military Operational Specialty surge that might arise in the future and they will be well prepared to meet any increased training requirements,? Pointer said.

Four Days Of Flight Without Need Of Fuel
During the flight, at NASA?s Dryden Flight Research Center at Edwards Air Force Base, California, Phantom Eye climbed above an altitude of 8,000 feet and remained aloft for 66 minutes at a cruising speed of 62 knots before landing. The aircraft exceeded what it achieved last year during its first flight when it flew at an altitude of 4,080 feet and remained aloft for 28 minutes.
Boeing is self-funding development of the environmentally responsible Phantom Eye, which generates only water as a byproduct of its propulsion system.
Following the first flight, Boeing upgraded the aircraft?s software and hardware, including the landing gear. The upgrades paid off in the form of a picture-perfect landing.
The Phantom Eye demonstrator is capable of carrying a 450-pound payload while operating for up to four days at altitudes of up to 65,000 feet.

Archangels Continue Satellite Control Legacy
Alpha Company at Fort Detrick began its existence as the first Satellite Operation Center in 1982.
With the launch of the Wideband Global Satellite 5, Alpha Company is now preparing to make the next move in advancing satellite communications to soldiers, sailors, airmen and Marines around the world.
WGS is the latest military communication satellite, with the first launching in 2007.
The WGS constellation continues to mature and Alpha Company will be taking on the newest mission.
Although this is not the first WGS in orbit, it will be a first for the 59 soldiers, one Department of Army civilian and 11 contractors who make up the Archangels.
?We continually endeavor to provide seamless communications to our users, and Alpha has created a yearlong training plan to ensure mission accomplishment with WGS,? said Capt. Mark Anderson, company commander.
?The Archangels have worked with a legacy satellite constellation known as the Defense Satellite Communication System for more than 30 years, and the move to WGS requires training on new equipment and most importantly?experience. Alpha Company has drawn from multiple resources to ensure our satellite controllers are prepared for this mission.
?We have the benefit of five geographically dispersed sister companies and other agencies to support our train-up. Our Sister Companies around the world are able to share a wealth of knowledge about this new system, but we are fortunate to have one of our sister companies, Bravo Company, located an hour down the road at Fort Meade, Maryland.?
According to Anderson their location allows Alpha Company to conduct new mission training by bringing WGS experienced soldiers here, as well as sending soldiers to the Bravo location. In addition to this new mission training, he said, the ability to learn from subject matter experts on new equipment and positions has proved invaluable.
?All of our satellite control equipment training is conducted on site, and takes up to six months for Soldiers to achieve their initial certification. This type of mission has no room for error, so training is a constant at Alpha Company.?
In addition to new mission training, Alpha Company has been able to work with multiple organizations to change their site configuration to utilize a WGS.?This has created the ability for our satellite controllers to experience a ?crawl, walk, run? training plan. This is the first time this site re-configuration has ever been attempted, and has proven to be a success. The ability to look at a different WGS before taking on our new mission has created a real world WGS operating environment at the Alpha Company site.?
This opportunity allows the company to test and validate new standard operating procedures, as well as give the satellite controllers real world experience, while having another operations center sit in the ?back-up? seat to coach Alpha Company along.
The 53rd Signal Battalion?s goal of providing the best customer support possible does not stop, no matter what systems they use. ?Alpha Company?s new WGS mission is no exception making our long range planning and execution so important,? Anderson said.
?This train-up utilizing organizations and agencies around the world will ultimately ensure the Warfighter has all the satellite resources needed to fulfill their mission for years to come.?
