A Strapdown Measurement of Vehicle Posture

Key Engineering Materials, 2010
Vehicle bodywork posture measurement has been a gordian technique in automotive．This paper presented a non-gyro bodywork posture measurement program．Using only one triaxial acceleration transducer with wheel speed encoders it provided a solution of calculating real-time bodywork posture．A lot of streamlining had been made within this program in order ...

Strapdown at the Crossroads

Navigation, 2004
Algorithms needed for processing raw strapdown inertial instrument outputs, long regarded as the exclusive province of experts, can be dramatically simplified for most applications. If extended coast durations are not required (because of repetitive updates), error propagation is also vastly simplified. After quantifying that coast duration in relation

Strapdown Latitude and Longitude Finder

2020 IEEE 6th International Conference on Methods and Systems of Navigation and Motion Control (MSNMC), 2020
The Strap down Latitude and Longitude Finder is an inertial system for latitude and longitude analytical determination. The computing algorithm of latitude and longitude determination of a moving vehicle is considered in this paper. The block diagram of the algorithm is presented. The algorithm is based on Strapdown Inertial Technology.

Strapdown Gyro Latitude Finder

2018 IEEE 38th International Conference on Electronics and Nanotechnology (ELNANO), 2018
A new method for latitude determination for the fixed base is presented. The method is based on strapdown inertial technol-ogy. The Inertial Measurement Unit is used for latitude determination. The IMU is composed of accelerometers, gyroscopes and a signal processing circuit.

A Strapdown Magnetic Azimuth Detector

Navigation, 1970
A system is described in which a strapdown 3-sensor magnetometer is used in conjunction with an inertial reference (such as a vertical gyro), to provide an indication of magnetic heading independent of aircraft attitude. The system eliminates the need for stable or pendulous mountings such as were used with previous azimuth detectors.

Improved strapdown coning algorithms

IEEE Transactions on Aerospace and Electronic Systems, 1992
Three improved algorithms for strapdown attitude computation utilizing accumulated gyro increments from the previous and current update are developed and evaluated analytically under classical coning motion. The error criterion of Miller is derived directly from the rotation vector concept.

Strapdown Guidance Error Analysis

IEEE Transactions on Aerospace and Electronic Systems, 1974
A crucial part of so-called ?strapdown? techniques for inertial guidance systems is the generation of the matrix of direction cosines relating the body axes to the reference axes. This is generally done by direct integration of a set of differential equations having the body angular velocities as inputs.

The use of strapdown technology in surveying

CISM journal, 1990
Inertial technology has been successfully used in surveying and geodesy for more than a decade. Although results in positioning and gravity vector determination have been excellent, the high cost of the stable platform systems, their bulkiness and their susceptibility to down times in a rough production environment, have somewhat limited the use of ...

Fiber gyroscopes for strapdown technology

SPIE Proceedings, 2000
ABSTRACT The gyroscopes are defined as devices, which can measure, autonomously, rotational motions relative to inertial space. They are of central importance for flight control, for navigation I orientation in the air at sea and on land, and also for stabilization I guidance of smart weapon systems. Benefiting from advances in semiconductor technology,

Reliability and Accuracy Prediction for a Redundant Strapdown Navigator

Journal of Guidance and Control, 1980
A comprehensive approach to the evaluation of the accuracy and reliability of a redundant navigation system is described. A Markov model of the redundant system is used to determine the probabilities of particular operational state time histories. Navigation system accuracies are associated with these state time histories through the use of a modified ...
