Alternative Navigation Systems
Overview
Alternative Navigation SystemsHoneywell’s Alternative Navigation technology enables commercial and military pilots to use sensors such as cameras, LiDAR, radar, radios, and star-trackers to augment and improve INS data. These technologies fill the void when GNSS signals are jammed, blocked, or unavailable. In a traditional INS-GNSS setup, GNSS signals correct errors that cause inertial systems to drift over time. Alternative navigation technologies can support INS in GPS-denied environments.Honeywell’s Alternative Navigation Offerings include:Vision Navigation: The Vision Aided Navigation system uses live camera feeds (optical and/or IR) and compares them with maps to provide a passive, un-jammable, highly accurate absolute position. This system was demonstrated on the Embraer E170, achieving GPS-like performance with a horizontal position accuracy of 10m CEP50 during GPS-denied conditions.Celestial Navigation:The Celestial Aided Navigation system utilizes star trackers to observe stars and Resident Space Objects (RSOs), providing a passive, un-jammable solution with GPS-like accuracy in GPS-denied or spoofed conditions. This system was recently demonstrated on a land vehicle, achieving an accuracy of 30m CEP50.Magnetic Anomaly Aided Navigation:This system measures the Earth's magnetic strength and compares it with magnetic maps to accurately identify the vehicle's position. The technology was successfully demonstrated on the Embraer E170.Radar Aided Navigation:Honeywell’s Radar Aided Navigation system uses radars to measure velocity and provide this information to INS, enhancing its accuracy.

Key Differentiators
Features & Benefits
- Alternative Navigation Systems use sensors such as cameras, radar, star trackers and magnetometers, to augment and/or aid inertial navigation systems
- Anti-Jamming and Anti-Spoofing Systems are for use in an environment where intentional low power GNSS jamming is likely to occur for short durations
- Provides corrections to inertial navigation systems in GNSS-denied environments.
