Ideal Aerosmith position and rate table systems provide angular position, rate and acceleration motions for development and production testing of inertial components and systems.
Rate Gyro. A system of three rate gyros, each oriented to one of three mutually perpendicular axes—roll, pitch, and yaw—can control a missile or aircraft by detecting angular rates and then generating proportional corrective signals. From: Modern Dictionary of Electronics (Seventh Edition), 1999
A rate gyro is a type of gyroscope, which rather than indicating direction, indicates the rate of change of angle with time. If a gyro has only one gimbal ring, with consequently only one plane of freedom, it can be adapted for use as a rate gyro to measure a rate of angular movement.
The mechanical Rate Gyro was a staple of most inertial stabilization systems until a few decades ago. The inertial property that the Rate Gyro uses is angular momentum. Angular momentum is constant unless some outside torque causes the frame in which the spinning rotor is held to rotate.
9 lut 2023 · The analysis of rate table market shows that the available rate tables feature the angular positioning accuracy of units of arc seconds [7–9]. The table platform is positioned about the set axis using the encoder (optoelectronic transducer of angular displacements) positioned on the same axis.
9 lut 2023 · Abstract—The paper considers a concept for designing the precision gyroscopic rate tables with digital control systems and inertial sensors as modern mechatronic control systems. Based on these systems, calibration algorithms for state primary standards of angular velocities can be elaborated.
Take into consideration that a MEMS gyro (working on coriolis law using vi-bratory excitation) and mechanical gyros (DTG) show a so-called g-depend-ent drift, i.e. they produce a drift (angular rate offset) dependent on linear acceleration and environmental vibration influence.
