Field 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 کاملAngular Rate Optimal Design for the Rotary Strapdown Inertial Navigation System
Due to the characteristics of high precision for a long duration, the rotary strapdown inertial navigation system (RSINS) has been widely used in submarines and surface ships. Nowadays, the core technology, the rotating scheme, has been studied by numerous researchers. It is well known that as one of the key technologies, the rotating angular rate seriously influences the effectiveness of the e...
متن کاملSimulation 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 کاملStrapdown Inertial Navigation Integration Algorithm Design Part 2: Velocity and Position Algorithms
This series of two papers (Parts 1 and 2) provides a rigorous comprehensive approach to the design of the principal software algorithmsutilized in modern-day strapdown inertial navigation systems: integration of angular rate into attitude, acceleration transformation/integration into velocity, and integration of velocity into position. The algorithmsare structured utilizing the two-speed updati...
