Evolution of military navigation is well underway - Story
December 01, 2014
Military navigation is undergoing several significant changes - including the introduction of international satellite constellations, a transition from Selective Availability Anti-Spoofing Module (SAASM) secure GPS to M-code, and an increasing interest in augmenting GPS with other technologies.

Cognitive radio's fate 'uncertain' as the spectrum battle plays out - Story
October 01, 2014
The U.S. Federal Communications Commission (FCC) is attempting to find a regulatory fix - striking a balance between national defense and economics - to eliminate electromagnetic spectrum inefficiencies. For now, this is making the exact role cognitive radio technology will play in the U.S. military's future unclear.

Next-gen shipboard electronics enhance data sharing and automation - Story
September 11, 2014
New design trends for shipboard electronics, such as those onboard the U.S. Navy's Littoral Combat Ship, focus on enabling enhanced data sharing capabilities and automation, along with a heavy emphasis on being prepared for electronic warfare.

Vetronics designers focus on reduced SWaP-C and enhanced C4ISR - Story
August 04, 2014
Government cutbacks may be slowing vetronics upgrades, but the defense industry is still focusing on initiatives to reduce size, weight, power, and cost (SWaP-C), as well as investing in command, control, communications, computers, intelligence, surveillance, and reconnaissance (C4ISR) capabilities.

U.S. rolls out big export policy changes for satellite industry - Story
June 04, 2014
The U.S. State Department and U.S. Department of Commerce are making big changes to long-standing export control policies as part of an effort to improve the international competitiveness of the U.S. space industrial base.

Unmanned underwater vehicles modernize U.S. Navy's sea-mine-hunting capabilities - Story
April 23, 2014
Since the end of World War II, sea mines have damaged or sunk four times more U.S. Navy ships than all other types of attacks. In the future, advances in fully autonomous Unmanned Underwater Vehicles (UUVs) - equipped with embedded computing technology - will play a key role in sea-mine countermeasures.
Avionics
Avionics upgrades enhance situational awareness for military pilots - Story
March 05, 2014
Military avionics retrofits to aircraft such as the B-1 Bomber are leveraging powerful commercial processors and high-speed networking in a distributed architecture to enable future capability upgrades. Meanwhile, safety concerns related to degraded visual environments are driving synthetic vision designs for rotary wing platforms.
Radar/EW
New capabilities on the way for airborne maritime surveillance radars - Story
January 29, 2014
Airborne maritime surveillance radars play a central role in the global homeland defense of more than 315,000 miles of worldwide coastline. While considered state-of-the-art, these radars continue to evolve to meet military customers' needs for persistent surveillance, automation, and continued tracking of targets as they move from sea to land.

GPS: Smaller, faster, jam-proof, and nearly everywhere - Story
December 17, 2013
Missile systems, Unmanned Aerial Vehicle (UAV) payloads, soldier radios, and other applications are seeing the benefits of miniaturization and enhanced performance in Global Positioning System (GPS) technology. However, GPS designs also require more elaborate anti-jamming techniques such as combining GPS with Inertial Measurement Units (IMUs) to combat new, sophisticated threats. Meanwhile, DARPA researchers continue to reduce GPS footprints as they combine a tiny IMU and timing capability on one substrate.

Evolving radio technology: SDR to cognitive radio - Story
October 09, 2013
Software-defined radio is no longer a military-only technology, as it has evolved beyond the now-defunct Joint Tactical Radio System (JTRS) program, can be found in commercial and defense applications worldwide, and is essentially a solved problem. Meanwhile, a big remaining challenge is the finite amount of available spectrum. Dynamic spectrum management is needed to navigate what is left and cognitive radio is seen as the technology that will make that possible.
