Topcon’s IP-S2 Mobile Mapping System overcomes the challenges of mapping linear features to a high level of accuracy. Accurate vehicle positions are obtained using three redundant technologies: a dual frequency GNSS receiver establishes a geospatial position; an Inertial Measurement Unit (IMU) tracks vehicle posse; and connection to the vehicle CAN bus or external wheel encoders obtains odometry information. These three technologies work together to sustain a highly accurate 3D position for the vehicle even in locations where satellite signals can be blocked by obstructions such as buildings, bridges, or tree lines.

• High definition mobile 3D mapping
• Dual frequency GNSS tracking
• High Accuracy 6-Axis IMU Integration
• Odometry inputs from on-board vehicle CAN bus or wheel encoders
• Supports multiple laser scanner models for operator and application flexibility
   

The IP-S2 standard system includes three high-resolution LiDAR scanners that cover the vehicle path at ground level and sweep the adjacent areas to a distance of 30 meters. A high-resolution digital camera can be added to provide 360 degree spherical images at a rate of 15 frames per second. Other sensors can be integrated to provide total flexibility of system configuration for a wide variety of applications. Sensor inputs are recorded and time stamped
