Broadband Real Time IP-Based Architecture for Vehicle Electronics

The U.S. Navy is seeking development of an open protocol and software and hardware solution to support the use of IP devices (e.g., an Ethernet-enabled sensor with an Ethernet-enabled mission computer system) over a STANAG-7221 link without interfering with a MIL-STD-1553 connection being used concurrently. To address this Navy need, Intellisense Systems, Inc. (Intellisense) proposes to develop a new Broadband Real Time IP-Based Architecture for Vehicle Electronics (BRAVE) plug and play module based on the unique adaptation of existing System on Chip (SOC) commercial PHY IP and VITA standards. All BRAVE circuit developments will be supported by Systems Modeling Language (SysML) digital modeling. Specifically, the innovative adaptation of existing VITA and modular open systems architecture (MOSA) standards and SysML modeling tools achieves a plug and play solution without any required user configuration once installed. In Phase I Intellisense will create and demonstrate the feasibility of a real-time broad band data bus capable of supporting legacy MIL-STD-1553 simultaneously supporting STANAG-7221 while also demonstrating transmission of data at a higher data rate with higher bandwidth traffic on a common data bus. Methods for bridging data and providing link status will be investigated. Issues associated with using STANAG 7221 will be investigated, and mitigation plans will be developed. The Phase I effort will include prototype plans to be developed in Phase II. In Phase II, we will further enhance the design and develop a prototype hardware solution with integrated software, which can drop in and provide IP connectivity at STANAG 7221 speeds over MIL-STD-1553 bus with no manual configuration required.
