Modular Open Radio Frequency Architecture Boot Camp
Authored by: Jerry Gipper, Vita Technologies.
Designers creating the next generation of embedded defense systems face several challenges getting their solutions off the ground. The newly launched Modular Open Radio Frequency Architecture (MORA) aims to enable the development of true open standards-based radio frequency and microwave modules and small form factor subsystem designs to reduce costs, foster commonality, and enable new communications capabilities.
Electronics are a key part of many defense platforms and are becoming more important as the content percentage is growing. However, the purchasing influence of defense programs has become a smaller percentage of the overall worldwide electronics industry. Complicating the issue is the demand to get new solutions to deployment in much shorter time frames to take advantage of the latest technology. This increase in reliance on electronics, reduction in purchasing power, and rapid shortening of time to deployment have created a challenging dynamic for system architects responsible for the design of next-generation defense platforms.
Over the years, many initiatives have emerged to drive standards for open, flexible platforms, with the most recent example being the U.S. Army’s VICTORY program. Recently, the U.S. Army’s Communications-Electronics Research, Development, and Engineering Center (CERDEC) launched a new initiative, the Modular Open Radio Frequency Architecture (MORA), which will enable the development of true open standards-based RF and microwave modules and small form factor subsystem designs that address the size, weight, and power consumption (SWaP) constraints of today’s ground vehicles. MORA is intended to leverage the work done under the VICTORY initiative by adding consideration for RF modules and subsystems.
About the MORA architecture
Current command, control, communications, computers, intelligence, surveillance, and reconnaissance (C4ISR) and electronic warfare (EW) systems use single-purpose hardware and software that aren’t shared beyond their defined functions and compete for limited resources on the platform. MORA decomposes radio systems into high-level components that enable sharing of hardware such as amplifiers and antennas. Low power distribution of RF signals improves overall system performance and efficiency through reduced cable loss. Use of software-defined radio technologies allows the same hardware to run different waveform applications to support a multitude of missions, including EW and communications.
Open Standards Drive Flexibility in Defense System Designs
Backed by broad support from government and industry, the release of SOSA Technical Standard 1.0 promises a new era of open standards-based system integration with flexibility and interoperability as its hallmarks.
Designing Rugged SWaP-Optimized MOSA Solutions for UUVs
As the U.S. Navy increases its investment in its fleet of unmanned undersea vehicles (UUV), suppliers of rugged commercial-off-the-shelf (COTS) subsystems, providing solutions for mission computers, network switches, and routers, and data storage are meeting the needs of these unique platforms.
The OMFV Next-Generation Combat Vehicle: A MOSA Milestone
The U.S. Army’s recent request for proposal (RFP) from industry for its new Optionally Manned Fighting Vehicle (OMFV), the planned replacement for the venerable Bradley Infantry Fighting Vehicle, represents a true milestone for the commercial off-the-shelf (COTS) industry.
What is Modular Open Radio Frequency Architecture (MORA)?
MORA is the U.S. Army's CCDC (Combat Capabilities Development Command) C5ISR Center's new architecture of open radio frequency interfaces for ground vehicles. Its purpose is to offer new capabilities, including reducing size, weight, and power (SWaP) and improving interoperability functions within the platform.
