CS7900 Real Time GPS Tool

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.

• Navigate roughness for milling or grinding corrections without painting marks on pavement
• Utilizes a precise GPS receiver with an optional satellite subscription
  • Accurate to within 0.1 meter (3.94 inches)
  • No base station needed
  • NTRIP and satellite based corrections available
• Use collected profiles from SSI equipment to determine grind locations
• CS7900 GPS equipment can be transferred to other vehicles, mills or grinders

• Can be mounted on any milling machine or diamond grinder
• Integrated computer dock with GPS and electronics
• RAM ball or magnet mounted to vehicle frame
• Optional Pelican case with battery backup
• Panasonic Toughbook runs the SSI Profiler software
• Can connect to 12VDC cigarette plug on equipment
• CS7900 also charges the Panasonic Toughbook

• Uses the profile data and GPS collected with an inertial profiler or profilograph system
• Can import ProVal grinding locations (IRI, MRI, etc.)
• Active display of exact locations to begin and end grinding; also shows height of trace peaks
• Displays current position by GPS and linear distance to next and previous grind locations
• Locations of grinding can be merged longitudinally and transversely
• View single or dual graphs (profile, continuous IRI)
• Zoom/pan mode for adjustable trace viewing
• Files with grinding locations are small: ~1MB/mile
• Data can be transferred to the grinder in under 5 minutes by USB
• Grinder operator does need to manually adjust the GPS-tracking system during grinding
• Current location displays on the elevation trace or continuous IRI plot
