Overview of Honeywell H-764 Embedded GPS/INS Navigation System
The Honeywell H-764 is part of the company's Embedded GPS/INS (EGI) family, designed to meet the most challenging military navigation requirements while offering civil interoperability capabilities. This self-contained, all-attitude, tightly coupled navigation system delivers critical outputs such as position, velocity, attitude (roll, pitch), heading, altitude, and time-synchronized data. Since its introduction in the mid-1990s, over 50,000 Honeywell EGIs have been produced, setting the benchmark for inertial performance in demanding navigation, pointing, stabilization, and flight control applications. The H-764 is widely used across military aircraft, offering flexibility through its compatibility with features like ADS-B, RNP/RNAV, WAAS, and more. The system is designed to easily integrate with other aircraft systems and can be certified to civil standards like DO-178B and DO-254, simplifying certification for advanced navigation capabilities.
Performance and Features of the H-764 EGI
The H-764 offers a range of key features that enhance its performance and flexibility, including support for blended INS/GPS outputs, free inertial, and GPS-only solutions. It is capable of meeting CNS/ATM mandates and provides advanced capabilities such as RNP/RNAV, autonomous LPV, and integration with WAAS and EGNOS. Additionally, it supports dual 1553, dual/quad Ethernet, ARINC 429, and RS-422 interfaces, ensuring robust data communication for various applications. The system's alignment modes include Gyrocompass, In-Flight Alignment, Ship Alignment, and Stored Heading Alignment. With a demonstrated MTBF of over 25,000 hours, the H-764 is designed for high reliability and long-term operation. The system's size options include the H-764 (7”x7”x9.8”) and its smaller variant, FALCN, offering flexibility for different platform requirements. Performance specifications include position accuracy of 5m with dGPS, velocity accuracy of 0.01 m/s, and heading accuracy of 0.015 degrees, making it ideal for precise military and civil applications.
