Multiposition alignment of strapdown inertial navigation system
IEEE Transactions on Aerospace and Electronic Systems, 1993The authors demonstrate that the stationary alignment of strapdown inertial navigation system (SDINS) can be improved by employing the multiposition/technique. Using an observability analysis, it is shown that an optimal two-position alignment not only satisfies complete observability conditions but also minimizes alignment errors.

Navigation Computation in Terrestrial Strapdown Inertial Navigation Systems
IEEE Transactions on Aerospace and Electronic Systems, 1977The problem of computing the translational velocity and position relative to earth, which has to be solved by the processor of a strapdown inertial navigation system is discussed. Several approaches are briefly examined with consideration given to the form in which the sensor data are generated and to the computational burden involved in each approach.

Gyrocompassing mode of the strapdown inertial navigation system
2017 IEEE 2nd Information Technology, Networking, Electronic and Automation Control Conference (ITNEC), 2017A gyrocompassing mode of the strapdown inertial navigation systems (SINS) was presented. SINS has been composed of Inertial Measurement Unit (IMU) and navigation computer. IMU consists of triad accelerometers, gyroscopes and a circuit of signal processing.

Improvement of strapdown inertial navigation using PDAF
IEEE Transactions on Aerospace and Electronic Systems, 1999A new application of PDAF (probabilistic data association filter) for improving the accuracy of autonomous strapdown inertial navigation systems (SINS) is presented. The proposed method is a terrain-aided navigation (TAN) algorithm based on landmark detection combined with a classical SINS.

A New Mathematical Formulation for Strapdown Inertial Navigation
IEEE Transactions on Aerospace and Electronic Systems, 1971A differential equation is developed for the orientation vector relating the body frame to a chosen reference frame. The time derivative of this vector is the sum of the inertially measurable angular velocity vector and of the inertially nonmeasurable noncommutativity rate vector.

Initial Alignment by Attitude Estimation for Strapdown Inertial Navigation Systems
IEEE Transactions on Instrumentation and Measurement, 2015This paper derives a novel initial alignment method for the strapdown inertial navigation system (SINS), which transforms the attitude alignment into an attitude estimation problem. The process model of the proposed initial alignment method by attitude estimation is established by decomposition of the attitude matrix.

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.

Correction of a Strapdown Inertial Navigation System During Descent in the Atmosphere
Mechanics of Solids, 2023The article deals with the problem on determining the angular position during descent on an apparatus with low lift-drag ratio. A solution is presented using the least squares method, which reduces to determining the orientation quaternion using a system of linear algebraic equations.
