Test Track and Off-Road Survey Profilers

CS9400-OR Accelerometer Only
The CS9400-OR only uses accelerometers to capture elevation profiles. The SSI electronics use a gain function to very accurately match the profiles from an inertial profiler. The installation and set up of this system is simple. Only a GPS antenna is outside of the vehicle. The collection speed is between 5-74mph. Use this system on roads with narrow passages where a laser sensor would not be practical.

CS9740 Grade Profiler
Additionally, a model of CS9740 is a longitudinal grade collection system which includes a sonic sensor and mounting hardware for a tow hook or a 2-inch hitch receiver. The system can be connected to a INS unit which returns PPK GPS corrections. This system can be used to report running grade and cross-slope all while being transported in a portable case.

CS8770 Survey Profiler
Based on the inertial profiler of the same model family, the SSI CS8770 is on a Polaris platform with 2-4 lasers mounted at least 40 inches (1016mm) off of the ground. The system uses the same collection software as the CS9500. It can be paired with a Zero-Speed inertial profiler for 0-100mph collection speeds for longitudinal profiles.

CS9500 Survey Profiler
Based on the inertial profiler of the same model family, the SSI CS9500 is mounted on a truck with 6 lasers mounted at least 40 inches (1016mm) off of the ground. The system uses the same collection software as the highway CS9500. It can be paired with a Zero-Speed inertial profiler for 0-100mph collection speeds for longitudinal profiles.

To avoid the need for a wheel mounted encoder if the collection speed is above 3 mph, opt for a GPS-DMI. Using GPS to determine distance has been accepted as the most accurate and repeatable way to measure distance instead of relying on a pneumatic tire that must be calibrated.

SSI’s GPS-DMI’s have an error tolerance less than 0.04%. Boost accuracy even more with an INS-DMI.

All off-road systems are used in demanding environments. Reduce the amount of parts outside the collection vehicle with a GPS-DMI.

The CS9400-OR or Accelerometer-only system has been used for years on tracks where laser sensors are impractical or unsafe. For tracks that have too much elevation change or can damage equipment with brush or bottlenecks. The accelerometers, computer, and electronics are all safe inside the cab. The only piece of equipment outside of the truck is a GPS antenna on top of the cab.

The CS9470 Grade Profiler uses a combination of an inertial profiler along with an INS-PPK system to capture accurate changes in elevation. The CS9470 can be configured as single or dual wheelpath hardware based on the CS9400 single laser hardware. The system is either mounted to truck tow hooks or on a 2-inch hitch receiver.

The sensor can be a laser for more accuracy or a sonic sensor for durability on tracks with dust, moisture, and debris.

The INS-PPK is used to accurately detect the grade changes. The PPK horizontal position is accurate to 10mm while the elevation is accurate to 25mm. The collection system uses the profiler’s sampling interval to index the changes in grade or cross-slope detected by the INS unit.

The CS8770 has a Polaris Ranger vehicle platform with four high standoff lasers to collect ~9-foot transverse width (2.7 meters). The collection software and processing is identical to the CS9500 Full Lane Survey Profiler.

The CS8770 would be used in situations with rugged terrain and in locations where a truck would not fit (like a bike path).

The CS9500 Full Lane Survey Profiler can be used offroad. The hardware would be mounted to have clearance over any obstructions. All other collection procedures would match the CS9500 platform.  The collection width with six lasers is up to 14-feet (4.3 meters)
