NovAtel® SPAN® Marine Profile is a GNSS receiver firmware enhancement designed to improve navigation performance in challenging marine environments. It combines GNSS data with inertial measurements to deliver continuous and accurate position, velocity, and attitude—even during extended GNSS outages. The firmware uses intelligent marine dynamics logic and patented Antenna Phase Windup technology to maintain reliable navigation. SPAN Marine Profile is compatible with all SPAN-supported Inertial Measurement Units (IMUs) and complements the SPAN Heave Solution for wave motion compensation.

Features

• Intelligent Marine Dynamics Logic: Tailored motion modeling for marine applications.
• Continuous Navigation Output: Maintains position, velocity, and attitude data during GNSS signal loss.
• Patented Antenna Phase Windup Technology: Corrects for rotational effects on GNSS signals caused by antenna movement.
• IMU Compatibility: Available for all SPAN-supported IMUs.
• Heave Output Integration: Works in conjunction with the SPAN Heave Solution for vertical motion correction.

Benefits

• Reliable Performance in GNSS-Denied Areas: Ensures uninterrupted navigation in offshore, harbor, and dynamic marine conditions.
• Improved Accuracy: Reduces errors in position and orientation using advanced modeling and sensor fusion.
• Scalable Integration: Compatible with a wide range of IMUs to meet different accuracy and budget requirements.
• Marine-Specific Optimization: Designed to meet the unique needs of marine navigation and mapping systems.
• Operational Continuity: Supports safe and efficient marine operations even during GNSS outages.
