INS-T-306 [GNSS-Aided Inertial Navigation Systems]

Tersus GNSS-Aided Inertial Navigation System (INS-T-306) is OEM version of new generation, fully-integrated, combined L1/L2 GPS, GLONASS and BDS navigation and high-performance strapdown system, that determines position, velocity and absolute orientation (Heading, Pitch and Roll) for any device on which it is mounted. Horizontal and Vertical Position, Velocity and Orientation are determined with high accuracy for both motionless and dynamic applications.

INS-T-306 utilizes advanced GNSS receiver, barometer, 3-axes each of calibrated in full operational temperature range Magnetometers, Advanced MEMS Accelerometers and Gyroscopes to provide accurate Position, Velocity, Heading, Pitch and Roll of the device under measure. INS-T-306 contains Tersus new on-board sensors fusion filter, state of the art navigation and guidance algorithms and calibration software.
