A new strapdown attitude algorithm
Journal of Guidance, Control, and Dynamics, 1983This paper develops the application to the strapdown attitude problem of the rotation vector concept, in which obtaining a solution for the rotation vector and updating the attitude quaternion are considered entirely separately. A new rotation vector algorithm is derived which takes three samples of gyro data per update, and offers greatly improved ...

Accurate Direct Strapdown Direction Cosine Algorithm
IEEE Transactions on Aerospace and Electronic Systems, 2019An assessment of the error inherent in a rotation vector algorithm utilized in a strapdown inertial navigation system is presented, which shows that the accuracy cannot be improved boundlessly only by increasing the number of the used samples. After reaching the upper limit for accuracy, increasing sample size would only enlarge the algorithm error ...

Strapdown stabilization for imaging seekers
Annual Interceptor Technology Conference, 1993Abstract : In space constrained applications such as tactical missiles, locating the inertial sensors off the platform simplifies packaging and may allow existing missile autopilot gyros to be used for platform stabilization. In strapdown stabilization, inertial sensors are fixed to the base of the inertial platform rather than directly on the platform

PERFORMANCE OF STRAPDOWN INERTIAL ATTITUDE REFERENCE SYSTEMS
Guidance and Control Conference, 1966This paper illustrates a method, verified by simulation, of analyzing the major error sources in a strapdown inertial attitude reference system consisting of three pulse-torqued gyros and a digital differential analyzer (DBA). Long-term propagation of commutation error is solved herein through a formulation of effective timing errors that vary \vith ...

Strapdown issues for airborne EO sensors
Digital Avionics Systems Conference, 1988STRAPDOWN ISSUES FOR AIRBORNE EO SENSORS Joseph E. Carroll and Peter Symosek Honeywell Inc, Systems and Research Center 3660 Technology Drive Minneapolis, MN 55418 The employment of strapdown Electro-Optic (EO) sensors on tactical aircraft raises a number of issues not previously addressed when gimbals separated the sensor head from the vchicle ...

Attitude Determination Algorithm for a Strapdown IMU
IFAC Proceedings Volumes, 1976Summary Concentrating on the quaternion approach to attitude determination for a strapdown inertial measurement unit, a technique is developed to facilitate selection of algorithmic order without resort to digital simulation. The procedure is demonstrated for algorithms through fourth order and for three specific types of vehicle motion, indicating a

Evaluation of the computational errors of strapdown navigation systems.
AIAA Journal, 1968The results of an evaluation of the computational errors for conventional, restrained, strapdown sensor mechanizations are presented. The analytic models of the computational errors (truncation, word length, integration scheme, integration interval, and sensor output resolution) presented were developed through detailed digital simulation of the ...
