Seamless integration with R2Sonic MBES
Compact IMU in a waterproof housing
Selectable accuracy configurations
Inertial aided RTK (Real-Time Kinematic) positioning
High immunity to GNSS (Global Navigation Satellite System) outages
Reduced cabling and processing modules with a single Ethernet port for data
Export license not required for most countries
Affordable pricing options
3-year standard warranty
