Small Form Factor Hardware Standards

Description:

OBJECTIVE: Define and demonstrate small form factor hardware standards that allow modularity smaller than 3U OpenVPX. DESCRIPTION: Command, Control, Communications, Computers, and Cyber (C5ISR)/Electronic Warfare (EW) Modular Open Suite of Standards (CMOSS), Sensor Open Systems Architecture (SOSA), and Hardware Open Systems Technology (HOST) hardware form factors leverage 3U and 6U OpenVPX to define hardware standards for military C5ISR systems. These standards allow multiple vendors to provide payload modules for C5ISR systems without the need to build to proprietary interfaces or replace entire systems. This increases competition and reduces the cost and effort required to upgrade C5ISR systems. While OpenVPX is suitable for many military ground and airborne platforms, it is not designed for small size, weight, and power (SWaP) platforms such as small unmanned aerial and ground vehicles. To address this gap and provide the benefits of CMOSS to more military programs, this effort will develop initial prototypes implementing open small form factor hardware specifications. As CMOSS, SOSA, and HOST leverage OpenVPX to define hardware standards, the proposed small form factor hardware specifications may leverage existing standards. Additional requirements for small form factor hardware standards: • Modularity is smaller than 3U VPX, with modules roughly MXM size (~ 80x80mm surface area) • Ethernet and PCIe connectivity • RF connectivity similar to VITA 67 • Optical connectivity similar to VITA 66 • Operates from -40°C to 85°C at cooling surface • Provide modularity similar to CMOSS standards [i.e. modularity between vendor payloads in a chassis (or equivalent) without modifications to the backplane (or equivalent)] The initial prototype should include a cooling solution, processing and transceiver modules, an Ethernet switch, and shared position, navigation and timing. Switch and PNT capabilities may be module-based or built into the chassis (or equivalent). Specific prototype performance requirements are not defined. The initial prototype shall be tested in a relevant environment to validate the specifications. These validation efforts will support further development of the specifications to mature them for transition to CMOSS. This effort will also develop verification requirements for the small form factor hardware specifications. These requirements will define the verification methodology to be used to test hardware for conformance to each specification requirement. In addition, this effort will design and develop a conformance test kit to automate conformance testing to the greatest extent possible. PHASE I: Develop an understanding of the key technical challenges that exist to support this concept. Conduct trade off studies on the use of existing small form factor hardware standards. Deliver initial open small form factor hardware standards. Provide an analysis of any performance limitations due to the hardware form factor. PHASE II: Design and develop prototype using the developed standards with a cooling solution, processing and transceiver modules, an Ethernet switch, and shared position, navigation and timing. Demonstrate the hardware with a relevant representative environment. Develop updated small form factor hardware standards for transition to existing relevant standards body. Develop an initial standards conformance plan and test kit for the small form factor hardware. PHASE III DUAL USE APPLICATIONS: Transition small form factor standards to existing standards body. Develop a payload for small SWaP platforms such as small unmanned aerial vehicles. Provide conformance testing and conformance test kits for small form factor hardware developers. REFERENCES: 1.
