Honeywell Radar Velocity System
Overview
The Honeywell Radar Velocity System (HRVS) is a small, lightweight, low-power radar-based navigation-aiding system. It uses millimeter wave sensing technology (60-64GHz or 76-81 GHz) providing range, velocity, and angle of objects. The HRVS can provide cm level-range accuracy and is impervious to environmental conditions such as rain, fog, dust, and snow.
Our HRVS can be used either as a velocity aiding source to inertial navigation systems or as an independent velocity sensing system in commercial and military applications.
Radar Velocity System Applications:
While the primary purpose of HRVS is to be an aiding source to inertial navigation systems, we can use HRVS also as a speed sensor or as a proximity warning system. Some of the applications where HRVS can be used are:
• Commercial Vehicles
• Military Vehicles
• Unmanned Aerial Systems
Key Honeywell Advantages
• Based on mmW sensor (60-64 GHz)
• Altitude <300m
• Indefinite precise hover as error doesn’t grow with time (unlike INS)
• Error approx. 1-2% distance travelled
• Cm level-range accuracy
• Impervious to environmental conditions such as rain, fog, dust, and snow
Honeywell Radar Velocity System for UAVs (HRVS-U)
This system consists of 4 HRVS-U units that provides velocity data to INS. Some of the features include altimeter measurement, depth mapping and ground avoidance sensing. Our HRVS-U is tested up to a maximum altitude of 300m and hence is an ideal solution for low-flying BVLOS operations.
Honeywell Radar Velocity System for Military Vehicles (HRVS-M)
The HRVS-M can be a good alternative to military vehicles that need to operate in GNSS-denied environments. Its low emission makes it almost undetectable even at close ranges. Emission data will be provided on request.
Honeywell Radar Velocity System for Commercial Vehicles (HRVS-CV)
In addition to its use as a navigation aid, the HRVS-CV can also be used as a speed sensor for niche commercial vehicles – especially long trailers. This system consists of one HRVS-CV unit which is fixed up to 1.5m above ground.
Our HRVS can be used either as a velocity aiding source to inertial navigation systems or as an independent velocity sensing system in commercial and military applications.
