MEMS-based rotary strapdown inertial navigation system
Measurement, 2013Abstract As the inertial navigation completely depends on the sensed acceleration and rotation rate by IMU, the sensor errors accumulate and eventually lead to diverged inertial solutions. Therefore the compensation of the inertial sensor errors is an effective approach to improve the SINS navigation performance.

System reset for underwater strapdown inertial navigation system
Ocean Engineering, 2019Abstract Conventional system reset methods establish the relationship between measurements such as position or heading and gyro drifts by the Psi equation, following which, they iteratively calculate the gyro drifts. However, these methods have some limitations in practice.

Doppler-Aided Low-Accuracy Strapdown Inertial Navigation System
Journal of Guidance, Control, and Dynamics, 1982This paper presents a covariance analysis of the performance of a Doppler-aided low-accuracy coarsely aligned strapdown inertial navigation system (INS), whose fine alignment takes place automatically in flight. It is shown that the fine alignment in azimuth, which requires turns, consists of in-flight gyro calibration and inflight gyrocompassing.

Navigation Computation in Terrestrial Strapdown Inertial Navigation Systems
IEEE Transactions on Aerospace and Electronic Systems, 1977The problem of computing the translational velocity and position relative to earth, which has to be solved by the processor of a strapdown inertial navigation system is discussed. Several approaches are briefly examined with consideration given to the form in which the sensor data are generated and to the computational burden involved in each approach.

Gyrocompassing mode of the strapdown inertial navigation system
2017 IEEE 2nd Information Technology, Networking, Electronic and Automation Control Conference (ITNEC), 2017A gyrocompassing mode of the strapdown inertial navigation systems (SINS) was presented. SINS has been composed of Inertial Measurement Unit (IMU) and navigation computer. IMU consists of triad accelerometers, gyroscopes and a circuit of signal processing.

Cascade Compensation Algorithm for Strapdown Inertial Navigation System
Advanced Materials Research, 2011The cascade compensation algorithm for no damp strapdown inertial navigation system (SINS) is designed based on control model and error characteristic of SINS level-loop. According to stability and frequency characteristic analysis for SINS level-loop, a compensation network, which is chosen to alter either the roots location or the frequency response ...

Strapdown inertial navigation system of pendulum type
Mechanics of Solids, 2014We consider two implementations of an isotropic oscillator to be used in the construction of a strapdown inertial system of new type [1]. The first implementation is a contact-free suspension of an electrically conductive ball used in electrostatic gyros, and the second implementation is a 3D combination of elastic constraints holding a mass point.

Navigation schemes for underwater robots using strapdown inertial navigation system
Proceedings IECON '91: 1991 International Conference on Industrial Electronics, Control and Instrumentation, 2002The authors deals with navigation schemes for underwater robots using strapdown inertial navigation systems. Compared to the current hydroacoustic position reference systems used for underwater robots, the strapdown inertial systems have longer operation distance, possess better autonomous ability, provide more complete navigation, and offer higher ...
