Sequential Piecewise Recursive Filter for GPS Low-Dynamics Navigation

TLDR
The design, implementation, and performance of a real-time estimation algorithm, referred to in this paper as the sequential piecewise recursive (SPWR) algorithm, for the global-positioning system (GPS) low-dynamics navigation system is described.
Abstract
The design, implementation, and performance of a real-time estimation algorithm, referred to in this paper as the sequential piecewise recursive (SPWR) algorithm, for the global-positioning system (GPS) low-dynamics navigation system is described. The SPWR algorithm for this application was implemented in single precision arithmetic (32 bit, floating point). Numerical results are presented covariance and filter gains at a slower rate than the state measurement update, and it uses U-D factor formulation to perform covariance computations. The SPWR algorithm saves real-time processing requirements without appreciable degradation of filter performance. Another important feature of the SPWR algorithm is that it incorporates pseudorange and delta-range data from each GPS satellite sequentially for navigation solution. The SPWR algorithm, for this application, was implemented in single precision arithmetic (32 bit, floating point). Numerical results are presented.

Discrete square root filtering: A survey of current techniques

TL;DR: In this article, the square root approach is proposed to solve the problem of discrete filtering in the absence of a state estimate and an error covariance matrix from stage to stage, which is equivalent algebraically to the conventional Kalman approach.

A Comparison of Discrete Linear Filtering Algorithms

TL;DR: Seven filter algorithms were presented in a recent survey paper, and were compared computationally (operations count) when relatively few observations were to be processed, and it is shown that for problems with even moderately large amounts of data, the information matrix and square-root information matrix formulations are computationally more efficient than the other methods considered.

Gram-Schmidt algorithms for covariance propagation

TL;DR: The U-D time update is shown to be less costly than the Schmidt method; and, except in unusual circumstances, it is within 20% of the cost of conventional propagation.
