Celestial Aided Navigation
Honeywell’s Celestial Aided Navigation (CNAV) system delivers precise geolocation in GPS-denied or GPS-disrupted environments. By using a star tracker to measure angular distances between stars and Resident Space Objects (RSOs), CNAV provides autonomous, infrastructure-free navigation that is both passive and highly resilient. Part of a Layered Navigation Strategy Celestial Aided Navigation is a critical component of Honeywell’s Alternative Navigation Suite, which also includes:Vision Aided Navigation Magnetic Anomaly Aided Navigation Radar Aided Navigation Together, these technologies form a multi-modal, resilient navigation architecture that ensures operational continuity in the most challenging environments—supporting both defense and commercial aerospace missions. Honeywell’s Alternative Navigation Architecture Enables seamless integration of Celestial Aided Navigation with other resilient modalities, providing a unified framework for autonomous, infrastructure-free positioning in GPS-denied environments. By supporting star tracker and RSO-based inputs, HANA ensures CNAV delivers GPS-like accuracy with passive, jamming resistant performance across air, land, and maritime domains.
