CS9550 Portable Survey Profiler
All of the CS9500 Features in a Smaller, Portable Package. Half-Lane Width Scanning with Single Track Smoothness
CS9500 Full Lane Survey Profiler
Full Lane Width Scanning At a Fixed Sampling Interval. Achieve 6mm Accuracy With Correction Points.
Collect Data at Highway Speeds With a Fixed Sampling Interval
SSI supplies users with SSI software to merge and correct multiple overlapping scans. Merging creates complete surface coverage and limits sensor drift. If a true 3D point cloud is desired, a survey crew captures points within the grid of the scan. SSI software corrects the vehicle scans to each other and to the surveyor’s elevation to achieve 6mm vertical accuracy for over 95% of the point cloud.
Operators don’t need to worry about radio signals and RTK. All GPS corrections are performed with Post-Processed Kinematic (PPK). SSI’s correction software can also add PPP GPS corrections or multiple PPK base stations.
- Fixed sampling interval set by operator before collection
- Maximum vehicle speed set by sampling interval
- Correction points are collected on the scanned surface by surveyor
- Vehicle scans only need to overlap a few inches
- 4,000 foot correction point spacing yields 95% of points within 6mm
- Inertial Profiler system is integrated within scanner
View Lane Lines with Laser Intensities
The lasers sensors also output the intensity value – or the contrast of black vs white. These intensity values can be used to detect lane lines or colored marks on the pavement or track surface.
Smoothness Based Design Models
Users may use the scan data and extract lines to create variable depth milling or paving models.
Through the SSI Profile Design module within the SSI Profiler software operators can fix cross-slope and set tolerances for cut depth or paving depth. This will output a GPS and station indexed model to be used for machine control or project estimates.
SSI is continually developing tools to identify and improve high roughness projects. Most projects don’t require machine control, but if you have questions contact SSI to help meet your project’s smoothness goals.
Accurate Cross Slopes
SSI systems can incorporate a military grade INS-GNSS system to measure vehicle dynamics. The INS system also improves GPS position output with more satellite constellations and position memory. Better position gives operators more accuracy for distance measurement with a GPS-DMI and location navigation.
This INS unit can be paired with SSI inertial systems to output accurate cross-slopes throughout the collection. The SSI software uses a simple calibration to offset mounting and sensor variables to report accurate measurements. These measurement have correlated within 0.1% of digital level verifications.
The cross-slope can be reported for every sample or averaged over an user-inputted interval.
Designed For Accuracy, Built For Efficiency
Different Vehicle Platforms - Same Technology
SSI’s CS9500, CS9550, and offroad profilers use the same technology with a different scale. The typical CS9500 system has six transverse lasers, CS9550 has three lasers, and the typical offroad Polaris survey system has four lasers. Each system uses the same software and the modules are interchangeable.
Data Quality Specifications
CS9500 or CS9550 acts as an inertial profiler capable of certifying under ASTM E950, AASHTO r56, or TxDOT 1001-S standards. No other system can reliably and easily convert and mimic an inertial profiler. IRI data is collected simultaneously with the survey point cloud.
We use more sensors for higher accuracy. The SSI scanners maintain higher point-to-point and survey elevation accuracy than comparable LiDAR or scanning systems.
