High-Speed Switched Serial Fabrics Improve System Design

Well into its third decade of widespread deployment, VME adopted the new VXS gigabit serial interface, clearly representing the most significant leap in backplane data transfer rates throughout its entire history. Because VXS delivered such a dramatic improvement in embedded system performance, the use of gigabit serial technology was extended to create VPX. The OpenVPX initiative followed shortly thereafter, as risk-averse government agencies mandated the need for industry-wide standards. The hallmark of any successful standard is that it continues to evolve with technology, and none offers a better example than VME’s evolution to VXS and VPX.

High-Speed Real Time Recording Systems

In today’s world of high-speed A/D converters operating in the gigahertz range, real-time signal recording has become a challenging task that requires specialized hardware and intelligent application software. When designing a real-time recorder capable of streaming sustained data to disk at rates of up to 5 GB/sec and higher, the system developer has to consider the limitations presented by the recorder’s operating and file systems, the limitations of disk drive technology, the hardware interfaces, and the RAID controller technology.

Putting FPGAs to Work in Software Radio Systems

FPGAs have become an increasingly important resource for software radio systems. Programmable logic technology now offers significant advantages for implementing software radio functions such as DDCs (Digital Downconverters). Over the past few years, the functions associated with DDCs have seen a shift from being delivered in ASICs (Application-Specific ICs) to operating as IP (Intellectual Property) in FPGAs.

Critical Techniques for High-Speed A/Ds In Real-Time Systems Handbook

To help define the meaning of “high-speed A/D” used in this handbook, we will be focusing primarily on A/D converters with sampling rates higher than 100 MHz. We will review sampling techniques, FPGA technology and we will present the latest Pentek high-speed A/D products and applications based on them.

Putting VPX and Open VPX to Work

Before the advent of OpenVPX, designers of embedded systems took advantage of the extreme connectivity offered by VPX (VITA 46), but were faced with a virtually unlimited number of possible implementations. Specific choices for the control and data channel assignments for each slot, the backplane connectivity, and serial fabrics were often made somewhat arbitrarily to suit the particular needs of the current system. Although following the general framework of VITA 46, each system tended to be so unique, that the boards and backplanes designed for one system were seldom usable in other systems, even from the same vendor.

Harsh, wet and dusty environments pose serious reliability issues for data collection. The SLICE IP68 data acquisition system is designed to measure physical signals in challenging test environments. With an ultra-small footprint of only 60 mm x 60 mm, the system can be embedded in most test articles with size and mass constraints. Its compact size means that it can be placed near the point of interest, eliminating the need for long cable runs, waterproof enclosures, or slip rings.

New Technologies Tackle UAV Challenges

Unmanned vehicles for air, land, and water represent an increasingly-important capability for virtually all military services worldwide. Because each new generation of device technology promises capabilities and higher levels of overall performance for unmanned vehicles of all types, military customers expect these benefits in the latest UAV offerings. To meet these expectations, systems engineers must deal with increasingly difficult problems of thermal management, power budgeting, EMI emissions and susceptibility, weight, size, cabling, connectors, antenna management, and command/control functions. Several new technologies and innovative packaging concepts now provide better solutions to these issues.

New Products: May 2018 Aerospace & Defense Technology

Rapid Deployment SIGINT Sensor

VStar Systems (San Diego, CA) announced the addition of a pod version of its MA-C SIGINT Sensor, the MA-C MiniPod™. Two active high frequency (HF) antennas allow for intercept and copy of land mobile radios from both direct Line of Sight (LOS) as well as Near Vertical Incidence Skywave (NVIS) signals for Beyond Line of Sight (BLOS) communication methods. The MA-C MiniPOD can be installed on most standard airborne racks/missile launchers for integration on a wide variety of platforms.

Protecting Critical Data on Unmanned Underwater Platforms

Emerging mission requirements from global defense forces are driving new programs and applications for Unmanned Underwater Vehicle (UUV) platforms. Like their airborne counterparts, UUVs are ideal for deploying Intelligence, Surveillance and Reconnaissance (ISR) mission payloads. To speed the development of these autonomous vehicles, system designers are turning to small form factor (SFF) Commercial off the Shelf (COTS) technologies previously proven in Unmanned Aerial System (UAS) deployments. These low-power SFF subsystems, including miniature network switches and mission computers, are ideal for use in UUVs for which any additional weight or power consumption can have significant detrimental effects on mission distance and duration. By selecting proven rugged COTS solutions, already tested and qualified to the extreme demands of MIL-STD-810G, MIL-STD-461, MIL-STD-704 and/ or RTCA/DO-160G standards for environmental, power, and EMI compliance, UUV system developers have found that they can greatly accelerate their program integration and reduce overall risk.
