Simulation of Strapdown Inertial Navigation System Using Modeled and Analysed Inertial Sensor Data
Inertial sensors comprise of two primary sensor units: accelerometers and gyroscopes. An inertial measurement unit (IMU) combines multiple accelerometers and gyros, usually three of each, to produce a three-dimensional measurement of specific force and angular rate (Weston and Titterton 2000). New designs of INS employ a strap down architecture, whereby the inertial sensors are fixed with respe...
متن کاملResearch on Initial Alignment and Self-Calibration of Rotary Strapdown Inertial Navigation Systems
The errors of inertial sensors affect the navigation accuracy of the strapdown inertial navigation system (SINS) and are accumulated over time in nature. In order to continuously maintain the high navigation accuracy of vehicles for a long time period, an initial alignment and self-calibration is necessary after the SINS starts. Additionally, the observability analysis is one of the key techniq...
متن کاملComparison of numerical integration methods in strapdown inertial navigation algorithm
Cviklovič V., Hrubý D., Olejár M., Lukáč O., 2011. Comparison of numerical integration methods in strapdown inertial navigation algorithm. Res. Agr. Eng., 57 (Special Issue): S30–S34. The numerical mathematical theory provides a few ways of numerical integration with different errors. It is necessary to make use of the most exact method with respect to the computing power for a majority of micr...
متن کاملAstronavigation System as an Autonomous Enhancement Suite for a Strapdown Inertial Navigation System: An Evaluation
The determination of spacecraft coordinates is embodied by a navigation solution with high degree of autonomy, high precision and reliability. The foremost requirement for the solution of this problem is a strapdown inertial navigation system (SINS), which is autonomous, reliable and jamming resistant, but at the same time, errors in SINS increase with time. Therefore, for the SINS error correc...
متن کاملAdaptive Fusion of Inertial Navigation System and Tracking Radar Data
Against the range-dependent accuracy of the tracking radar measurements including range, elevation and bearing angles, a new hybrid adaptive Kalman filter is proposed to enhance the performance of the radar aided strapdown inertial navigation system (INS/Radar). This filter involves the concept of residual-based adaptive estimation and adaptive fading Kalman filter and tunes dynamically the fil...
