Guide for computation of horizontal geodetic surveys by Harry R Kahler( Book )

4 editions published in 1960 in English and held by 23 WorldCat member libraries worldwide

A collection of procedures, suggested formats, and descriptions of practices is presented as an aid in geodetic computing. The methods discussed for the most part have proven satisfactory where production work is carried out with desk calculators. This publication is intended as a working guide and is an explanation of methods, many of which are little known to nonspecialists. (Author)
Results of varying investigations into approaches to geodetic parameter estimation( Book )

2 editions published in 1966 in English and held by 3 WorldCat member libraries worldwide

Presented are the results of varying investigations into approaches to geodetic parameter estimation and documentation of associated computer programs developed under the effort. Results of an investigation to utilize integrated range rate data in an unconstrained solution for station position, integration constant and bias estimates are presented. The approach appears to be feasible, however large amounts of data will most likely be required in order to overcome the effects of serial correlation introduced by the integration. It would be of maximum use in instances where there are large uncertainties in the force model or where no model can be utilized. (Author)

Project scorpio: satellite calibrator of ranges photographed in orbit( Book )

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

Project SCORPIO is a satellite system primarily designed to calibrate range instrumentation equipment for the Atlantic Missile Range (AMR). As a result of high quality tracking data collected to satisfy this mission, the program also will provide valuable geophysical data useable for research to support missile and satellite operations. In addition, it will refine the geocentric coordinates of several world-wide tracking stations critically needed for military space programs. The satellite will carry a MISTRAM, a GLOTRAC and a DPN-66 transponder along with an optical beacon which can be photographed against a stellar background. The satellite package will weigh approximately 300 pounds and will be placed into a low eccentricity orbit, about 500 miles above the earth. The inclination of the orbital plane, dictated by the location of the electronic tracking stations, is to be on the order of 40 degrees. The optical tracking net will be world-wide, employing PC-1000 ballistic type cameras as well as the optical tracking equipment available on the AMR. (Author)
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.

Solutions of long-line geodetic azimuths by photogrammetric techniques by Armando Mancini( Book )

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

Formulas are derived for the determination of geodetic azimuths between two nonintervisible distant points employing photogrammetric tech niques. Solutions are presented for the classi cal HIRAN azimuth reductions wherein only the azimuth component of observed directions are used. This is followed by a treatment of the 'space' solution utilizing observations on passive or active satellites. The classical method is developed on the Universal Transverse Mercator Grid (UTM); the latter directly on a spheroid. (Author)
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)

The program described was devised primarily to provide acquisition data to a ground-based instrumentation net consisting mainly of various types of cameras. The cameras are employed to photograph a flashing strobe light that is mounted on each pole of the ANNA geodetic satellite that is magnetically stabilized along its spin axis. Provisions were made to compute a satellite ephemeris by a differential correction procedure as the satellite is stepped around the orbit in some desired increment of time
