The Zero-Speed systems have been proven on multiple DOT certification tracks under AASHTO r56 requirements. The new technology can even achieve reference level repeatability above 98% and be a replacement to walking reference devices. New sensors and software integration make low speed collections possible. By pairing additional elevation sensors with vehicle compensation and high resolution GPS, the Zero-Speed system maintains the accuracy of traditional inertial profilers. Come see why the Zero-Speed Inertial Profiler is an exclusive product to SSI.
