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 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 کاملField Programmable Gate Array Based Parallel Strapdown Algorithm Design for Strapdown Inertial Navigation Systems
A new generalized optimum strapdown algorithm with coning and sculling compensation is presented, in which the position, velocity and attitude updating operations are carried out based on the single-speed structure in which all computations are executed at a single updating rate that is sufficiently high to accurately account for high frequency angular rate and acceleration rectification effect...
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 کاملIntegration of a GPS aided Strapdown Inertial Navigation System for Land Vehicles
The estimation accuracy of a low-cost inertial navigation system (INS) is limited by the accuracy of the used sensors and the imperfect mathematical modeling of the error sources. By fusing the INS data with GPS data, the errors can be bounded and the accuracy increases considerably. In this project, a low-cost in-house constructed inertial measurement unit (IMU) and an off-the-shelf GPS receiv...
