Honeywell Radar Velocity System
Overview
The Honeywell Radar Velocity System (HRVS) is a compact, lightweight, and low-power radar-based navigation-aiding solution designed for resilient UAV operations. Leveraging advanced millimeter wave sensing technology (60–64 GHz or 76–81 GHz), 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 Honeywell Compact Inertial Navigation System (HCINS) and the GPSdome Anti-Jamming System. When combined with HCINS, HRVS enables UAVs to navigate in fully GPS-denied environments with a position error of less than 3% of distance traveled.

Key Differentiators
Key Benefits
- Enables features: Velocity aid, altitude measurement, depth mapping, ground avoidance
- GNSS-Outage Resilience: Maintains accurate navigation in GNSS-denied environments with minimal deviation; error remains ~1–2% of distance traveled and does not grow over time
- High-Precision Sensing: mmWave sensor (60–64 GHz) delivers centimeter-level range accuracy and resolution down to 4 cm, with range up to 170 m and velocity support up to ~250 m/s.
- Indefinite precise hover as error doesn’t grow with time (unlike INS)
- Range measurement resolution down to 4cm
- Reliable in All Conditions: Operates effectively in rain, fog, dust, and snow, with consistent performance day or night
- Robust Navigation Support: Enables velocity aiding, altitude measurement, depth mapping, ground avoidance, and precise vertical velocity—ideal for autoland and hover
- Seamless Integration: Guaranteed compatibility with Honeywell systems like HCINS, providing range and velocity aiding to inertial navigation devices
