EL SEGUNDO, Calif. – Navigation and guidance experts at Raytheon Technologies Corp. needed a real-time software operating system for the company's Military Global Positioning System User Equipment (MGUE). They found their solution from Green Hills Software in Santa Barbara, Calif.
Officials of the Raytheon Intelligence & Space segment in El Segundo, Calif., are choosing the Green Hills INTEGRITY-178 tuMP real-time operating system (RTOS) for the Raytheon Military Global Positioning System User Equipment (MGUE) Increment 2 Miniature Serial Interface (MSI) with Next-Generation Application Specific Integrated Circuit (ASIC).
Raytheon designers are developing one MSI card for aviation and maritime navigation systems and another for ground-based systems, and will use INTEGRITY-178 tuMP will be used in both solutions running on the Arm processor-based application-specific integrated circuit (ASIC).
Raytheon selected the INTEGRITY-178 tuMP RTOS based on the company's use in previous programs and for its ability simultaneously to meet safety and security requirements such as DO-178C design assurance level (DAL A) and the NSA-defined separation kernel protection profile (SKPP) for high robustness security.
The MGUE is the GPS receiver for the modernized GPS Enterprise. It can receive military code (M-Code) from newer satellites, including GPS-III. M-Code is a more robust and jam-resistant form of GPS that also uses more modern and flexible encryption methods to resist RF spoofing.
The MGUE Increment 2 MSI program is developing a small M-Code ASIC and receiver card that consumes less power while increasing functionality, security, and performance. The smaller card will enable use in handheld and dismounted applications as well as mounted, maritime and aviation platforms.
The U.S. Government Accountability Office (GAO) in Washington estimates that about 700 different types of weapons will require M-Code cards and M-Code-capable receivers, including ships, aircraft, ground vehicles, munitions, and handheld devices.
Raytheon was one of three companies awarded by the U.S. Space Force's Space Systems Command for the MGUE Inc 2 MSI with Next-Generation ASIC program. The other two companies are the L3Harris Technologies Interstate Electronics segment in Anaheim, Calif.; and Collins Aerospace in Cedar Rapids, Iowa.
