GNSS Inertial Navigation Systems
NovAtel's SPAN® technology tightly couples our OEM precision GNSS receivers with robust Inertial Measurement Units (IMUs) to provide reliable, continuously available, position, velocity and attitude-even through short periods of time when satellite signals are blocked or unavailable.
Combined Systems
Compact, single enclosure GPS+INS system.
Inertial Measurement Units (IMUs)
IMUs from leading manufacturers. Range of performance levels available.
What is an Inertial Navigation System and how does it work?
An Inertial Navigation System (INS) is a system that is used to compute relative position over time from rotation and acceleration information provided by an Inertial Measurement Unit (IMU). An INS uses the measurements from the IMU to provide position, velocity and attitude (roll, pitch and azimuth) calculations. When an INS is combined with GNSS, the two navigation techniques augment and enhance each other. The stable relative position of the INS can be used to bridge through times when the GNSS solution is degraded or unavailable.
