Dirt Surface Characteristics
SSI’s profiling equipment experience allowed us to add dirt, gravel and off road surfaces to our collection types. SSI offers multiple systems from accelerometer only systems to wide scan survey vehicles. Topography measurements of dirt surfaces are also supported by SSI’s mobile surveying systems.
Off Road Collection Platforms
SSI offers multiple systems for off road testing.
- CS9400-OR is an accelerometer-only system for rough terrain where a laser sensor outside the vehicle is not practical
- CS9470 Grade Profiler uses an IMU and a laser or sonic sensor to profile single path grades and cross-slopes. Optional use of PPK-INS for more accurate position and elevation
- CS8770 is a survey scanner on a Polaris platform. This system can collect severely rough terrain with survey accuracy.
- CS9500 Full Lane Profiler configuration can be used on the highway and light trails, or secondary roads. Most CS9500’s have low standoff lasers for a Zero-Speed inertial profiler, so their access is limited.
