This high-precision dual-axis rate table features an integrated temperature chamber, designed for inertial navigation system (INS) testing and calibration. It provides ultra-fine angular positioning (±2″), a wide angular speed range (0.001°/s – 2000°/s), and reliable performance for aerospace, UAV, marine, and defense applications.
The robust horizontal UT structure supports payloads up to 40 kg and enables dynamic motion simulation under extreme environmental conditions. This system ensures repeatable, precise calibration of gyroscopes, accelerometers, optical devices, and servo systems.
