Three-Axis Motorized Pan-Tilt Unit
This three-axis motorized pan tilt unit (PTU) mainly consists of a three-axis mechanical unit with inner, middle, and outer gimbal frames, together with a drive and control system and a measurement unit. Its core function is to provide high-precision position and rate motions for dynamic attitude simulation, as well as for the testing and calibration of inertial devices such as integrated inertial packages.
Features
- High load capacity up to 30 kg, tabletop Φ450 mm
- Three-axis rotation accuracy up to ±5″
- Positioning accuracy up to ±2″ (outer/middle frames)
- Wide rate range: from ±0.001°/s
- Inner-frame acceleration above 200°/s²
- Three axes intersecting within a Φ0.5 mm sphere
Applications
For aerospace, inertial navigation, and military testing, this motorized gimbal turntable is mainly used for the performance testing and calibration of inertial navigation components (IMUs), gyroscopes, accelerometers, and other high-precision devices.
