Available in PDF, EPUB and Kindle. Book excerpt: Kalman filtering techniques were applied in evaluating the use of lunar beacons in estimating the state of a lunar vehicle. Range and/or range-rate measurements were used as the observational data. Results show that the error in the beacon location can be reduced from an initial error of 1.73 kilometers to approximately 0.2 kilometer, by the use of earth-based observations. The use of on-board observations of the lunar beacons can contribute significantly to lunar orbit estiniation when used in conjunction with earth-based observations. Locating the beacons to provide state information that was difficult to obtain from earth-based measurements provided beneficial. On-board observations also proved adequate in estimating the state of a lunar vehicle when they were the only data source available.

Download or read book Application of Statistical Filter Theory to the Optimal Estimation of Position and Velocity on Board a Circumlunar Vehicle written by Gerald L. Smith and published by . This book was released on 1962 with total page 68 pages. Available in PDF, EPUB and Kindle. Book excerpt: Statistical filter theory is employed to develop a method for determining the best possible estimate of the position and velocity of a space vehicle in the midcourse phase of flight. Results of a computer simulation are given to illustrate the performance attainable. An onboard system is visualized in which the source of information is an arbitrary sequence of observations of space angles, corrupted by measurement errors. The scheme is in effect a dynamical time-varying filter, implemented by a digital computer, which processes the incoming data to compute an up-to-date optimal estimate of position and velocity.
