Celestial Aided Navigation
Overview
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:
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.
