Advances in Lightweight Electronics Protection

Lightweighting continues to be a key topic for the aerospace, avionics and defense industries as new metals and composites are being integrated into end products and assemblies with the goal of decreasing overall system weight. As technologies continue to evolve, with components often decreasing in size and increasing in complexity, the materials used to manufacture and protect the latest components and systems are also improving. Whether used in commercial or military aircraft, rockets, satellites, terrestrial or water vessels, or the latest in unmanned air, land and sea vehicles; systems within these industries must meet similar requirements – assemblies, components and electronics must be both lightweight and designed to withstand harsh operating conditions.

Powering Outer Space: An In-Depth Look at Aerospace Battery Technology

With space’s extreme environments, there is never a one-size-fits-all battery. Nor is any space mission ever the same, so customized batteries for each operation are essential. Saft, has been powering outer space for more than 50 years. Saft’s first battery was launched into space in 1966 aboard the D1A “Diapason”, which was powered with nickel cadmium (Ni-Cd) technology. To date they are the only battery manufacturer to supply all battery technologies used in space: Nickel (Ni-Cd, Ni-H2), primary lithium (Li-SO2, Li-SOCl2 and Li-MnO2) and rechargeable lithium or lithium-ion (Li-ion).

Using High Bandwidth Oscilloscopes to Analyze Radar and Electronic Warfare Systems

Whether for multi-channel analysis, or for wider analysis bandwidth in a measurement, high bandwidth oscilloscopes offer an alternative to traditional spectrum and signal analyzers for both pulsed RF aerospace/defense and I/Q vector modulated communications application measurements. Signals with spectral content beyond 1 or 2 GHz are now being created to support the higher resolution requirements in radar systems and to move the vast amounts of information in new communications systems.

Bio-inspired Airborne Infrastructure Reconfiguration (BioAIR)

Conventionally, most autonomous mobile nodes, including unmanned aerial vehicles (UAVs), are operated remotely by human operators. As such, forming a mobile communication network to connect several airborne or ground-based nodes with multiple remotely controlled UAVs can be prohibitively costly and very inefficient because many operators are needed. Furthermore, the operators need to control the deployed UAVs, while coordinating with others and monitoring the performance of the deployed communication network. Hence, a feasible solution must support collaborative communication, sensing and navigation. BioAIR offers a solution to this problem by enabling multiple UAVs to autonomously control themselves based on network performance.

EMI Analysis Software Helps Telescope Group Simulate RFI Mitigation

Challenging Einstein’s seminal theory of relativity to the limits, how the very first stars and galaxies formed just after the Big Bang, the study of dark energy and the vast magnetic fields in the cosmos, and the age old question “Are we alone in the Universe?” – these are some of the key scientific goals of the Square Kilometer Array (SKA) project, led by the SKA Organization from Jodrell Bank Observatory in the UK, supported by 11 member countries: South Africa, Australia, Canada, China, Germany, India, Italy, New Zealand, Sweden, The Netherlands, and the United Kingdom.

Aspen Systems are supplying Environmental Control Units (ECU’s) for critical communications electronics cooling for the Joint Light Tactical Vehicles (JLTV) being produced by Oshkosh Corporation. The first vehicle order under this contract was released by the Army on March 23, 2016 for 657 vehicles. The initial JLTV production contract calls for a delivery total of nearly 17,000 vehicles, while the total program is expected to result in over 50,000 JLTVs delivered to the US Military.

The F-35 Joint Strike Fighter is the Department of Defense's next generation strike aircraft weapon system for the Navy, Air Force, Marines, and US allies. The fifth-generation fighter brings cutting-edge technologies to the battlespace of the future. On July 31, 2015, the first squadron was declared ready for deployment after training, an important part of which was accomplished with Lockheed Martin’s high-fidelity Full Mission Simulator (FMS). RGB Spectrum’s DGy™ recording and streaming codecs and multi-channel video servers are core components in the FMS.
