Collect profile data at a high rate without external sensors. The CS9400-OR system is preferred for vehicle tracks which are not suitable for expensive sensors outside the vehicle. SSI has developed an accelerometer only system that closely matches with the inertial profiler on same surface tests.
CS9400-OR vs Inertial Profiler
Simple Hardware
One or Two 10g accelerometers mounted inside the vehicle
Electronics enclosed within vehicle
GPS receiver can mag-mount to top of vehicle
GPS-DMI for distance measurement
Software
Collections performed within SSI Profiler
Calibrations for accelerometer is only setup process
Output RMS, IRI, MRI, HRI based on the vehicle suspension response
Optional Features
GPS-DMI or INS-DMI
INS-PPK corrections
Medium or high resolution GPS receivers with multiple constellations
