The Air Force has launched a tender
for the launch of a next-generation Global Positioning System satellite
, releasing a RFP for the launch vehicle production, mission integration and launch operations. The latest Lockheed Martin GPS-III satellite was recently announced
as being ready for system testing.
GPS IIIA concept
GPS-III satellites, in conjunction with their companion OCX ground control, system are the Global Positioning System (GPS) future. They offer big advantages over existing GPS-II satellites and GCS, but most of all, they have to work. Disruption or decay of the critical capabilities provided by the USA’s Navstar satellites would cripple both the US military, and many aspects of the global economy.
The time-based GPS service is the most-used application of Einstein’s Theories of Relativity. GPS has become part of civilian life in ways that go go far beyond those handy driving maps, including crop planting, timing services for stock trades, and a key role in credit card processing. At the same time, military class (M-code) GPS guidance can now be found in everything from cruise missiles and various precision-guided bombs, to battlefield rockets and even artillery shells. Combat search and rescue radios rely on this line of communication, and so does a broadening array of individual soldier equipment.
This DII FOCUS article looks at the existing constellation, GPS-III improvements, the program’s structure, its progress through contracts and key milestones, and extensive PTN (Positioning, Timing & Navigation)/ GNSS (Global Navigation Satellite System) research links.

It’s 2020. A US soldier sits down with a village sheikh, with an unusual robot in tow. The sheikh greets him courteously, respectfully, in flowing Arabic. At the appropriate time, the robot offers the same speech in English. The soldier nods, speaks, and gives a command, whereupon the robot offers dependable translation that’s even customized to the local dialect. Offshore, an intelligence analyst sorts through a combination of intercepted emails, recorded cell phone conversations, and document archives, looking for patterns and connections. She’s not fluent in Arabic, but the same technology used by the soldier is providing usable translations for her searches – asking her questions as needed, and helped by embedded clarifications and tags.
Thanks to a 2003 DARPA program, The world got to know Siri, the show-stealing component of Apple’s iPhone 4S. DARPA’s 2011 BOLT program aims to take the next step, from a silicon intermediary between man and machine to an intermediary between people. Even as it also provides a powerful back-end translation system for traditional intelligence tasks. It’s one of a family of ongoing translation research efforts, all aiming to solve a persistent and expensive problem for the US military.

Shadow 200 in Iraq
Limitations on UAV use are imposed by the threat of collisions between UAVs and manned aircraft. An RQ-7 Shadow UAV is definitely large enough to create real problems if it hits a helicopter or other aircraft, and a UAV’s extremely narrow field of view is a lot less safe than the awareness available to a human in a cockpit. Worse, many UAVs are small enough that a potential collision may not be noticed by other aircraft until it’s too late. There have already been accidents.
This isn’t just a military problem. It also represents the largest barrier to widespread civil UAV use. Europe’s EDA has a program underway to address deconfliction, the Israelis are looking into it, the US military is funding research from multiple UAV controllers to SWARMs, and even private contractors are busy searching for the key that will unlock a vast UAV market. The ultimate goal is a system that’s small enough to equip smaller and more affordable tactical and civil UAVs, as well as larger and more expensive military UAVs like the MQ-9 Reaper and RQ-4 Global Hawk.
A recent project sponsored by the US Army, and led by Lockheed Martin, is bringing that goal closer – and may have ramifications for the inter-service balance of power.

As of July 2007, Raytheon Technical Services held the US Army contract for live training support, Computer Sciences Corp. (CSC) carries the contract for virtual training (simulators), and General Dynamics the one for constructive training (computer models & game-like simulations). More than 3,400 contractors served more than 150 manned sites and 458 unmanned sites with training devices world-wide.
The U.S. Army’s Program Executive Office, Simulation, Training and Instrumentation (PEO-STRI) office has been working for the last couple of years on a new approach that does away with the 3 domains, in order to put the full focus on delivering whatever training support is needed and appropriate, in whatever manner works best. The Warfighter Field Operations Customer Support (Warfighter FOCUS) contract would consolidate operations, maintenance, systems integration and engineering support services for the Army’s live, virtual and constructive training systems into a single 10-year, $11-12 billion package once existing contracts expire on Oct 31/07.
On one side was the Warrior Training Alliance (WTA), led by prime contractor Raytheon Technical Services Company LLC and Computer Sciences Corporation. One the other side was the Warfighter FOCUS Alliance (WFA), led by General Dynamics, Lockheed Martin, Northrop Grumman, and Saab. Each team had a roster that included other major and minor players, and DID details both teams below. The winner was the Raytheon-led WTA, and integration is now proceeding…
