Investigation of space probe data conditioning and reduction methods( Book )

1 edition published in 1963 in English and held by 1 WorldCat member library worldwide

The data collection and processing methods of the scientists conducting rocket probe and satellite experiments were studied. The best procedures to be used for data conditioning, decommutation, and digitizing for entry into a large scale computer were recommended and a trial program written and tested to substantiate the recommendations. The results of this research are presented. The digitizing equipment, the desired data formats, and the data processor programs are described. (Author)
Generalized bandwidth compression and attribute extraction using the experimental dynamic processor and display system( Book )

1 edition published in 1966 in English and held by 1 WorldCat member library worldwide

A completely new version of the Attribute Extraction program for the Experimental Dynamic Processor is described. The size of symmetric matrices which can be diagonalized has been increased from 160 to 224. Special display programs, including a visual documentation system, are briefly described. A special eigenvalue-eigenvector evaluation technique, preliminary results of the display processor beam characteristics study, and a method for bandwidth compression of binary data are presented.

Long line azimuth determination from range and optical measurements( Book )

1 edition published in 1963 in English and held by 1 WorldCat member library worldwide

A solution is developed in vector form for determining the azimuth of long lines from timed simultaneous observations of range and direction to a target at altitude from the terminal points of the line. The solution is independent of the distance between the two points and timing requirements are not at all severe. The twenty millesecond accuracy required for ballistic camera orientation is entirely adequate. A sample computation is included along with an error analysis, a FORTRAN program listing and flow charts. (Author)
Research on correlation type data processing systems( Book )

1 edition published in 1962 in English and held by 1 WorldCat member library worldwide

The development of the high speed digital computer made the construction of large scale data processing and large real time control systems feasible. The improvement of sensor and communication devices led to systems of great sophistication. Improvement must now be made in the machine's ability to work with deteriorated or oth rwi e more compl data. T e ample u ed i textual and spoken data. This data is important to system op ration in two ways; (1) a large volume of communication between systems is by these means; and (2) the simplification of t e hum n's communication with the machine directly. The analysis of the data by different methods can be expected to develop better means of deriving information from signals without a priori knowledge of their exact content and to develop more efficient transmission schemes for those signals. The methods used are basically s atistical. (Author)
The attribute derivation and display system for the experimental dynamic processor( Book )

1 edition published in 1964 in English and held by 1 WorldCat member library worldwide

A new version of the Attribute Extraction program for the Experimental Dynamic Processor is described. This new version takes advantage of the drum storage and display capability of the DIGIGRAPHIC equipment that has been added to the DX-1. The several display programs and the Attribute program have been compatible and work under a common executive routine, the DEXTER system. The order of solvable matrices has been increased from 50 to 160. Some preliminary results are given. The special display programs are described. The Power Method to find eigenvalues and eigenvectors of large matrices is described. A simulation of a proposed optical eigenvalue and eigenvector processor is described. (Author)
ERROR ANALYSIS 3-D AZIMUTH (OPTICAL)( Book )

Contents: Errors in least squares solution of linear equation Application to the long line Azimuth problem Errors in the long line Azimuth Estimation of data variance in least squares
CALIBRATION SATELLITE STUDIES( Book )

1 edition published in 1964 in English and held by 1 WorldCat member library worldwide

Described are results of the mathematical and systems engineering investigations that were performed on calibration of range instrumentation by means of a calibration satellite. These studies are based on the premise that the instrumentation systems to be calibrated using such a satellite are the MISTRAM and GLOTRAC CW systems and the C-Band and S-Band pulse radar systems. It was further defined, based on present Air Force program planning, that the basic vehicle to carry the calibration payload would be the SATAR (Satellite for Aerospace Research) sponsored by the Office of Aerospace Research. The capabilities of SATAR do not allow the simultaneous inclusion of transponders compatible with all the above systems on one vehicle. These studies have preserved flexibility in techniques within these constraints. (Author)
Differential orbit correction and station locator program doc - ii( Book )

1 edition published in 1964 in English and held by 1 WorldCat member library worldwide

The analysis and programming associated with performing a differential correction to orbital elements and/or station positions from weighted observations of range, range rate, azimuth-elevation and/or right ascension-declination on close earth satellites are described. The ephemeris computation considers perturbations due to the earth's gravitational potential as described by a spherical harmonic representation through n = m = 5, the lunar gravitational potential, air drag and radiation pressure. All observations may be simulated in punched card form for the purposes of conducting geometric studies. (Author)
Special utility programs to enhance the performance of an on-line medium size processor used for statistical information extraction and evaluation( Book )

1 edition published in 1967 in English and held by 1 WorldCat member library worldwide

A new method for determining eigenvectors and eigenvalues in the Attribute Extraction Process is described. A software package for the new floating point arithmetic unit of the Experimental Dynamic Processor, a visual documentation system for DEXTER programs, and a general data display are described. Several debugging programs, graphic software, special display programs, and utility routines are presented. (Author)
Atmospheric perturbations on nearly circular satellite orbits( Book )

1 edition published in 1963 in English and held by 1 WorldCat member library worldwide

This report describes a simple technique for determining the effects of air drag on a nearly circular satellite orbit. Over any single orbit, the change in orbital period and radius can be obtained as a function of sub D A/M. Several graphs are included where Sub D 2 with observa tions of the ANNA 1b Satellite

Datum and/or station location from ballistic camera observations on satellites( Book )

1 edition published in 1964 in English and held by 1 WorldCat member library worldwide

The results of a study to determine the accuracy with which datums can be positioned relative to the geocenter from ballistic camera observations on a satellite are presented herein. The study utilizes simulated observations on a postulated satellite borne optical beacon. The satellite is taken to be in a 400 nm, low eccentricity orbit. Recommendations are made for maximum utilization of such a satellite for geometric geodetic purposes (i.e., datum and/or station location.) Conclusions are that a three-dimensional uncertainty of five to ten meters can be achieved utilizing the short arc technique (an arc of 4000 to 5000 miles.) It is felt that long arc reductions for geometric purposes with ballistic camera observations only, are operationally impractical and although theoretically attractive, should be dismissed as having any major potential in a geodetic satellite program.
