A Dynamic Attitude Measurement System Based on LINS

A Dynamic Attitude Measurement System Based on LINS

A dynamic attitude measurement system (DAMS) is developed based on a laser inertial navigation system (LINS). Three factors of the dynamic attitude measurement error using LINS are analyzed: dynamic error, time synchronization and phase lag. An optimal coning errors compensation algorithm is used to reduce coning errors, and two-axis wobbling verification experiments are presented in the paper....

A quaternion-based Attitude Estimate System Based on a Low Power Consumption Inertial Measurement Unit

Accurate and real-time tracking of the orientation or attitude of rigid bodies has traditional applications in robotics, aerospace, underwater vehicles, human body motion capture, etc. Towards human body motion capture, especially wearable devices, the use of a longer time has always been a challenge for several weeks or several months continuously, so a low-cost chip and a low computational co...

Dynamic-Structural Attitude Unit: Concept and Measurement

Adaptive attitude controller of a reentry vehicles based on Back-stepping Dynamic inversion method

This paper presents an attitude control algorithm for a Reusable Launch Vehicle (RLV) with a low lift/drag ratio (L/D < 0.5), in the presence of external disturbances, model uncertainties, control output constraints and the thruster model. The main novelty of proposed control strategy is a new combination of the attitude control methods included backstepping, dynamic inversion and adaptive cont...

A Wearable Attitude-Measurement System Using a Fiberoptic Gyroscope

An attitude-measurement system (TISS-5-40) has been developed to achieve a wearable sensor for individuals. This equipment is one of the inertial sensor systems having three Žberoptic gyroscopes and three accelerometers. Heading stability of 1 deg./hr. (1 s ) and attitude accuracy of 60.5 deg. have been demonstrated. At present, some of the attitude-measurement Systems have been applied in the ...
