SANTA BARBARA, Calif. Green Hills Software announced the selection of the INTEGRITY-178 tuMP real-time operating system (RTOS) by Raytheon Intelligence & Space (RI&S) for their offering of the Military Global Positioning System User Equipment (MGUE) Increment (Inc) 2 Miniature Serial Interface (MSI) with Next-Generation Application Specific Integrated Circuit (ASIC).
RI&S claims it is developing one MSI card for aviation and maritime systems and another MSI card for ground-based systems, and INTEGRITY-178 tuMP will be used in both solutions running on the Arm processor-based ASIC.
According to officials, RI&S selected the INTEGRITY-178 tuMP RTOS based on its use in previous programs and for its ability to meet safety and security requirements. Those requirements included DO-178C DAL A design assurance and the NSA-defined separation kernel protection profile (SKPP) for high-robustness security.
The Military GPS User Equipment is the GPS receiver for the modernized GPS Enterprise, and it is capable of receiving military code (M-Code) from newer satellites, including GPS-III. M-Code is designed to be a more robust, jam-resistant form of GPS that also uses more modern and flexible encryption methods to make it resistant to spoofing.
