Use the same software as SSI inertial profilers to navigate large corrective grinding equipment to roughness. Mounted the CS7900 to a milling or diamond grinding machine and correct roughness without marking the ground with paint. The CS7900 is portable and can also be used in any vehicle to lay out grinds.
SSI offers many high accuracy GPS options down to 4cm with a subscription. Most CS7900 systems have a 0.75-meter accuracy which is adequate for corrective grinding operations.
