Embedded GPS-aided INS (EGI) for military aircraft

Visit Website Contact

Honeywell’s embedded GPS-aided inertial navigation systems (EGIs) are self-contained units designed to support demanding military-grade navigation, pointing, stabilization and flight control applications. Certified to DO-178 and DO-254, the systems deliver a variety of highly reliable outputs, including:

  • Linear and angular acceleration, velocity and position
  • Attitude (roll, pitch)
  • Platform azimuth
  • Magnetic and true heading
  • Altitude
  • Body angular rates
  • Time tags in Coordinated Universal Time (UTC) synchronized time

EGI with M-Code

EGI – Embedded GPS/INS

All units can be provided with robust anti-jam capabilities to protect against modern jamming and spoofing threats and challenging GPS-denied environments. The EGIs can also be equipped with M-Code functionality, providing secure and future-proofed navigation capabilities for military aircraft operators.

The H-764 is available as a legacy unit with a larger chassis to maintain commonality with older systems, while the FALCN provides the same features and performance of the H-764 in a smaller and lighter package.
