Honeywell has recently announced the release of a new and highly resilient EGI system, designed to operate effectively in GPS-denied environments

Honeywell introduces the Resilient Embedded GPS/Inertial Navigation (EGI) system, an advanced navigation technology designed to address the interference and spoofing issues GPS can face in modern warfare. The system combines GPS and inertial navigation technologies to provide precise position, velocity and time information to meet the needs of a wide range of applications.The EGI system builds on the Honeywell H-764 and FALCN, and is designed specifically to meet military requirements in areas where GPS interference and spoofing problems are prominent.

In this area, Septentrio also introduced its advanced Septentrio M3 Pro+ GNSS board, a versatile OEM GPS/GNSS receiver board that combines more than two decades of Septentrio innovation.The M3 Pro+ is a multi-frequency, multi-constellation GNSS receiver with top-notch positioning performance. and has the flexibility to be used as a base station or mobile station receiver. In dual antenna mode, it provides heading and pitch or roll information in addition to reliable and accurate positioning. It also features a data update rate of 100Hz.

Features of the Septentrio M3 Pro+ GNSS board include:
AIM+ Advanced Interference Suppression and Monitoring (AIM+) technology, providing built-in protection against intentional and unintentional interference and spoofing, using sophisticated sampling and mitigation mechanisms.
Optimal SWaP (size, weight and power), providing the lowest power consumption for RTK positioning of any similar device on the market, meaning it can run for longer on a single battery charge, providing better value in field applications. Top performance in challenging environments, including LOCK+, IONO+ and APME+ technologies that automatically adjust receiver parameters in response to mechanical vibration or shock, provide state-of-the-art ionospheric interference suppression and effective separation of direct and reflected signals for improved positioning accuracy and measurement quality.
Easy integration provides fully documented interfaces, commands and data messages. The included GNSS receiver control and analysis software, RxTools, allows receiver configuration, monitoring, and data logging and analysis.

Honeywell plans to launch the EGI's engineering unit in early 2026 and certifiable units shortly thereafter. This schedule allows for comprehensive testing and enhancements to ensure the system achieves the reliability and performance required for critical military applications.

In addition, Honeywell's EGI system offers the following features:
Improved resistance to GPS jamming and spoofing through the integration of M-code and atomic clocks.
Open architecture allows for rapid integration and changes, enabling the platform to quickly adapt to new NAVWAR capabilities.
System design allows adaptation to mission-critical requirements while maintaining certified safety-critical systems.
The ability to detect and mitigate GPS threats without compromising the accuracy of the navigation solution has been demonstrated through simulations, rigorous testing and real-world applications.

This innovative technology from Honeywell demonstrates the company's leadership in high-performance IMUs and navigation systems, as well as its continued commitment to improving the reliability of military and civil navigation systems. With this advanced EGI system, Honeywell is able to provide customers with a critical solution for maintaining navigation capabilities in complex and threatening environments. At the same time, the Septentrio M3 Pro+ GNSS board provides users with another high-performance option to meet the need for precise positioning in a variety of challenging environments.
