Abstract:	Integrated Guidance Systems LLC (IGS LLC), a joint venture between Honeywell and Rockwell Collins, has developed the next generation, Deeply Integrated (DI) guidance, navigation and control product which will meet the emerging demands of military applications. The guidance, navigation and control Flight Management Unit (FMU) is based on Selective Availability Anti-Spoof Module (SAASM) and Micro Electromechanical System (MEMS) sensor technology and is housed in a small, light weight, low power package. In addition to meeting the demands of the military’s gun-hardened guided projectile and missile applications, the FMU has applicability in soldier personal navigation systems and military/commercial attitude, heading and reference systems (AHRS). When coupled with Honeywell’s second generation C++ based Embedded Computer Toolbox and Operating System (ECTOS™ IIc), the FMU can be utilized easily and effectively for rapid prototyping demonstration (including customer generated guidance and control software), as well as full production systems. Utilizing the latest processor technology, the FMU has been designed to accommodate the next generation INS/GPS Ultra Tightly Coupled (UTC) algorithms. The UTC algorithms, together with the embedded hardware anti-jam electronics, enables the FMU to perform in the otherwise potentially disabling environment of today’s battlefield. The FMU has been tested to 20,000 G’s (battery backed state), successfully demonstrating the hardware components survive and perform after exposure to the high G environment. This paper presents an overview of the FMU and ECTOS™ IIc software. The hardware architecture and technical specifications of the FMU will be presented, along with a more detailed look at its high G and anti-jam capability. Performance will be reviewed as well as the IGS LLC’s approach to providing a deterministic IEEE 1394b bus protocol. Finally, the software architecture, capability, and customer usability / programmability features of ECTOS™ IIc will be described.
