Honeywell Radar Velocity System
The Honeywell Radar Velocity System (HRVS) is a small, lightweight and low-power radar-based navigation-aiding system.
The RVS uses millimeter wave radar (mmWave) technology (60-64GHz or 76-81 GHz) and outputs range, velocity and angle of objects.
What is a Radar Velocity System?
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.
Resilient Navigation Packages to Avoid GNSS Outages
Honeywell’s philosophy of resilient navigation revolves around three layers of resiliency achieved by a combination of GNSS anti-jamming, inertial navigation and alternative navigation systems.
Option #1: GNSS Anti-jamming and Anti-spoofing Systems
If you operate in an environment where intentional low power GNSS jamming is likely to occur for short duration, we recommend a GPSdome.
Option #2: Intermittent GNSS Outages
Honeywell’s Compact Inertial Navigation System (HCINS) provides consistent navigation during intermittent GNSS outages like urban canyons or scenarios where anti-jamming systems don’t work.
If you operate in an environment where intentional high power GNSS jamming is likely to occur for short duration, we recommend a GPSdome and HCINS.
Option #3: Continuous GNSS Outages
Alternative navigation systems navigate during continuous GNSS outages for a longer duration. We have various alternative navigation systems in development and our first offering is a Radar Velocity System (HRVS) that utilizes millimeter wave radar technology to provide velocity measurements to aid inertial navigation systems.
Option #4: Long Duration GNSS Disruptions
If you operate in an environment where there is less likelihood of intentional GNSS disruptions, but you expect long duration GNSS disruptions (such as BVLOS missions), we recommend using our HCINS and HRVS.
Option #5: Powerful GNSS Jamming
If you operate in an environment where intentional high power GNSS jamming is likely to occur for a long duration, we recommend using GPSdome, HCINS and HRVS.
