Basic principles of strapdown inertial navigation systems
2004The previous chapter has provided some insight into the basic measurements that are necessary for inertial navigation. For the purposes of the ensuing discussion, it is assumed that measurements of specific force and angular rate are available along and about axes which are mutually perpendicular.

Identification modeling of inertial sensors' parameters of strapdown inertial navigation systems
2017 2nd International Ural Conference on Measurements (UralCon), 2017The paper aims at improving the accuracy of the strapdown inertial navigation systems (SINS). The calibration is carried out using a 2-axial motion simulator. The influence of motion simulator instrumental errors is investigated. They effect the errors in the determination of calibration coefficients for SINS accelerometers and gyroscopes.

In-Motion Alignment Algorithm of Strapdown Inertial Navigation Systems
2018 DGON Inertial Sensors and Systems (ISS), 2018Strapdown Inertial Navigation Systems (SINS) estimate position, velocity and angular orientation upon signals acquired by inertial sensors– accelerometers and gyroscopes - stiffly fixed on a vehicle. A SINS begins operating by the initialization process which provides initial position, velocity and alignment.

Research on the Vibration Control for Strapdown Inertial Navigation System
2010 Second International Conference on Intelligent Human-Machine Systems and Cybernetics, 2010This paper investigates the vibration control for strap down inertial navigation system (SINS) based on the theoretical analysis and the simulation confirmation. Firstly, the disadvantage of passive vibration control technique commonly used for SINS at present is pointed out that it is only effective at high frequency.

A strapdown inertial navigation system for the flat-Earth model
IEEE Transactions on Aerospace and Electronic Systems, 1997The development of a strapdown inertial navigation system (SINS) for aerodynamically controlled vehicles, which are limited to altitudes below 30 km (that is, a small distance compared with the Earth's radius of about 7000 km), or using the so-called flat-Earth model (FEM), is the principal objective of this work. In dealing with the FEM equations, the

A “telescopic” system in the calibration problem for strapdown inertial navigation systems
Moscow University Mechanics Bulletin, 2012An algorithm for the bench calibration of strapdown inertial navigation systems is studied. This algorithm was developed at the Moscow Institute of Electromechanics and Automatics. A mathematical model for the calibration process is constructed. A method for representing the original calibration problem in the form of a standard estimation problem is ...

Testing strapdown inertial navigation systems on a test bench
Gyroscopy and Navigation, 2010The methods and procedures used for testing a marine strapdown inertial navigation system (SINS) on a rocking platform of a test bench are considered. Some formulas describing the errors of various parameters of SINS due to the vessel’s orientation are calculated.
