Honeywell Radar Velocity System
Overview
The Honeywell Radar Velocity System (HRVS) is a compact, lightweight, and low-power radar-based navigation-aiding solution designed as a velocity aiding accessory to the HGuide range of INS/GNSS Navigators to support resilient land and aerial navigation.
HRVS delivers precise range, velocity, and angle measurements with centimeter-level accuracy—regardless of environmental conditions such as rain, fog, dust, or snow.
Unlike vision-aided navigation systems, HRVS requires no maps or prior environmental data. It operates effectively from ground level up to 1 km altitude across all terrains (excluding still water) and in all weather conditions, making it a versatile and robust velocity-aiding source for inertial navigation systems.
HRVS is part of Honeywell’s Resilient UAV Navigation Suite, which also includes the HGuide o480, HGuide HCINS and HGuide n580.
When combined with HRVS, these Navigators can navigate in fully GPS-denied environments with a position error of between 0.5% and 3% of distance traveled.
