Two-Axis Gimbal
A CMM Optic two-axis gimbal is designed to sustain environmental and performance requirements typical of unmanned aerial vehicle (UAV) sensor systems. These gimbals contain compact direct drive brushless DC motors, high-precision rotary encoders, precision ball bearings and optional solid-state gyroscopic sensors.
TWO AXIS GIMBAL FEATURES
An optically-coated aluminum mirror or alternative optical payload is supported on either side by a one-piece yoke comprising the elevation axis assembly. The azimuth motor and encoder are contained in a black anodized aluminum base. Precision ball bearings in duplex configurations maximize radial and axial stiffness in both axes while ensuring smooth, low friction and reliable service.
An optional digital control system can be configured for a wide variety of electronic interfaces and operational modes including vector scanning and line-of-sight stabilization. The hardware consists of a 16-bit 150 MHz Digital Signal Processor (DSP) and 16-bit dual Digital-to-Analog Converters (DAC). Serial flash allows for in-the-field code updates.
