SANTA BARBARA, Calif. Green Hills Software, embedded safety and security company, announced that its INTEGRITY-178 Time-Variant Unified Multi-Processing (tuMP) RTOS running on a quad-core ARM Cortex-A53 CPU has been selected by Northrop Grumman Corporation for the Embedded Global Positioning System (GPS)/Inertial Navigation System (INS)-Modernization (EGI-M) program.
According to the company, key factors in the selection of INTEGRITY-178 tuMP include its ability to run a DAL-A partition across multiple A53 cores, its built-in DAL-A functionality and tools for mitigating multicore interference per CAST-32A, and its certified conformance to the FACE 3.0 Technical Standard, including all the multicore requirements.
EGI-M is based upon a modular, open-systems architecture and supports rapid insertion of new capabilities to enable accurate and reliable positioning, navigation, and timing (PNT) information, even in GPS-denied conditions.
EGI-M incorporates a military code (M-code) GPS receiver that adds robustness to interference of GPS signals. The lead platforms for EGI-M are Northrop's E-2D Hawkeye and Lockheed Martin's F-22 Raptor, but it is designed to be scalable to any manned platform and larger unmanned vehicles.
