SPAN GNSS+INS technology combines GNSS positioning with inertial navigation system (INS) measurements like velocity, attitude and heave. In a solution customized for hydrographic survey applications, the 3D positioning provides accurate measurements even through extended GNSS outages.
By deeply coupling the GNSS and inertial measurements, GNSS tracking is refined to aid acquisition of satellite signals. This process strengthens the accuracy of your current position, and extends positioning reliability.
SPAN GNSS+INS technology, developed by Hexagon | NovAtel, has delivered assured positioning for over 15 years. Now optimized for the marine environment and for hydrographic survey applications, SPAN technology is scalable with multiple different IMUs like our IMU-ISA-100C and IMU-μIMU-IC, the LD900 receiver, and Quantum visualisation software.
