INS-T-306
GNSS-aided Inertial Navigation Systems
Inertial Navigation Systems (1) 640x340px.jpg
The Tersus GNSS-Aided Inertial Navigation Systems INS-T-306 is OEM version of fully-integrated, combined GPS L1/L2, GLONASS and BeiDou navigation and high-performance strapdown system. The INS-T-306 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.
Inertial Navigation Systems (2) 640x340px.jpg
The INS-T-306 utilizes an advanced GNSS receiver, a barometer, 3-axis magnetometers, MEMS accelerometers and gyroscopes to provide accurate position, velocity, heading, pitch and roll of the device under measure. The INS-T-306 contains the Tersus new on-board sensors fusion filter, state-of-the-art navigation and guidance algorithms and calibration software.
