| SPANTM Technology integrates the iMAR FSAS-EI-SN IMU with NovAtel precision GNSS for enhanced navigation performance. Benefits of combined GNSS Inertial Navigation NovAtel’s SPAN Technology brings together two different, but complementary technologies: GNSS positioning and Inertial Navigation. The absolute accuracy of GNSS positioning and the stability of IMU gyro and accelerometer measurements combine to provide a 3D position, velocity and attitude solution. Unlike GNSS-only navigation systems, the solution is stable and continuously available, even through periods when GNSS signals are blocked. Specific benefits of the iIMAR-FSAS SPAN system The FSAS-EI-SN IMU is manufactured in Germany by iIMAR. The IMU features closed-loop technology with gyro biases of less than 0.75 degrees per hour and accelerometer biases of less than 1mg. The IMU is triggered by the NovAtel receiver so that all IMU measurements are time synchronized to GNSS measurements. For commercial applications, this IMU is available within 2 months ARO and only German export approval is necessary. Features
