RAC Series:  Vehicle Installed Distance Measuring Instruments

 

Accurate, reliable and easy to operate, our RAC units are THE BEST distance measuring instruments (DMIs) on the market. These cost-effective units save time and money by allowing personnel to measure distance, accurate up to 1 foot per mile, while driving as fast or slow as necessary. Results can be read directly off the DMI's display.

 

Much safer than the old 'Hand-Wheel', these units will pay for themselves in increased productivity in a matter of days.

Sensor Types

 

Using either the RAC Geo's on-board GPS distance sensor, or an external distance sensor, the RAC DMIs provide you with the best combination of accuracy and convenience.

Distance sensors do the behind-the-scenes work of the RAC distance measuring instruments. These sensors read and modify the data coming from your vehicle and send a signal to the RAC telling it when to count distance.

There are currently four types of distance sensors that can be used to do distance measuring:

-Internal GPS (RAC Geo II Only)

-External OBD

-External Modular

-External Magnetic

Why are there four types?

Because distance measuring instruments are used by a wide variety of customers who often have different needs and in a wide variety of vehicles that don’t all work the same.

The simple breakdown of the four is that the on-board GPS and AutoLink OBD sensors are the newest and easiest to install (plug and play, no tools required), but that ease of install trades a degree of accuracy. The magnetic and modular sensors are more precise, but also more intensive to install, requiring getting under the hood and splicing wires.

 

The accuracy of the GPS and OBD sensors are about 5 feet per mile, while the magnetic and modular sensors are about 1 foot per mile.

Introduced in 2010, the AutoLink is the simplest to install external distance sensor that's ever been on the market. While it is not as precise as the modular or magnetic sensors (1 foot per 1000 feet vs. 1 foot per mile), its overall accuracy is suitable for a large variety of applications.

Introduced in 2003, the Modular Distance Sensor is the most widely used distance sensor in the world today. It provides 1 foot per mile accuracy and is easier to install than the magnetic sensor. However, it is not compatible with some vehicles.

The Magnetic Distance Sensor uses the oldest technology of the three sensors, but when properly installed, remains the most accurate. While the installation of this sensor is the most intensive of the three sensor types, there are no vehicle compatibility issues.

New Features

 

The RAC Plus I and RAC Geo II offer new features and improvements to the older RAC-100/200 units, and highlight our continuing efforts to constantly improve.

WAAS enabled, 12 channel GPS receiver capability allows 2D GPS accuracy of approximately 2 meters.

Without WAAS, depending on the location in the continental US and satellite accessibility, horizontal GPS accuracy is approximately 6 meters.

RACPro Software

RACPro is data analysis & reporting software for the RAC Geo II Distance Measuring Instruments.

RACPro is a Windows-based program for use with the RAC Geo II Distance Measuring Instruments. It allows you to download surveys that have been collected with the RAC Geo II and once that data is in the program it can be analyzed and edited in a variety of ways. Comprehensive reports, which can be customized to suit your needs, can be produced.

 

Data can also be collected and sent from the RAC to a computer in real time.

 

Data that has been collected with GPS coordinates can also be mapped using the optional MapPoint software or Google Earth. Note that mapping with Google Earth requires an active Internet connection. Mapping with MapPoint can be done offline.

 

Introduced in 2010, this program replaced the older WinRAC Plus software.

 

RACPro is actively maintained and free technical support is available both online and via phone.
