The disks are thought to be precursors to planetary systems, and the outflows are thought to be a necessary phase in the formation of a young star, helping the star to get rid of angular momentum and energy as it makes its way onto the main sequence. The possible connections to planetary systems and stellar astrophysics makes these topics especially broad, appealing to generalists and specialists alike. The CD not only contains papers that could not be printed in the book but allows the authors to include a fair amount of data, often displayed as color images. 410 0$aLecture Notes in Physics,$x0075-8450 ;$v465 606 $aObservations, Astronomical 606 $aAstronomy?Observations 606 $aAstrophysics 606 $aGeophysics 606 $aAstronomy, Observations and Techniques$3https://scigraph.springernature.com/ontologies/product-market-codes/P22014 606 $aAstrophysics and Astroparticles$3https://scigraph.springernature.com/ontologies/product-market-codes/P22022 606 $aGeophysics/Geodesy$3https://scigraph.springernature.com/ontologies/product-market-codes/G18009 615 0$aObservations, Astronomical. 615 0$aAstronomy?Observations. 615 0$aAstrophysics. 615 0$aGeophysics. 615 14$aAstronomy, Observations and Techniques. 615 24$aAstrophysics and Astroparticles. 615 24$aGeophysics/Geodesy. 676 $a523.8/8 702 $aBeckwith$b Steven$4edt$4http://id.loc.gov/vocabulary/relators/edt 702 $aStaude$b Jakob$4edt$4http://id.loc.gov/vocabulary/relators/edt 702 $aQuetz$b Axel$4edt$4http://id.loc.gov/vocabulary/relators/edt 702 $aNatta$b Antonella$4edt$4http://id.loc.gov/vocabulary/relators/edt 906 $aBOOK 912 $a996466816103316 996 $aDisks and outflows around young stars$9914146 997 $aUNISA LEADER 05755nam 22006735 450 001 9910958628803321 005 20250801063359.0 010 $a9783709132975 010 $a3709132975 024 7 $a10.1007/978-3-7091-3297-5 035 $a(CKB)3400000000110510 035 $a(SSID)ssj0001006095 035 $a(PQKBManifestationID)11542835 035 $a(PQKBTitleCode)TC0001006095 035 $a(PQKBWorkID)11112781 035 $a(PQKB)10448157 035 $a(DE-He213)978-3-7091-3297-5 035 $a(MiAaPQ)EBC3100436 035 $a(EXLCZ)993400000000110510 100 $a20121227d1997 u| 0 101 0 $aeng 135 $aurnn#008mamaa 181 $ctxt 182 $cc 183 $acr 200 10$aGlobal Positioning System $eTheory and Practice /$fby Bernhard Hofmann-Wellenhof, Herbert Lichtenegger, James Collins 205 $a4th ed. 1997. 210 1$aVienna :$cSpringer Vienna :$cImprint: Springer,$d1997. 215 $a1 online resource (XXIII, 391 p.) 300 $aBibliographic Level Mode of Issuance: Monograph 311 08$a9783211828397 311 08$a3211828397 320 $aIncludes bibliographical references and index. 327 $a1 Introduction -- 1.1 The origins of surveying -- 1.2 Development of global surveying techniques -- 1.3 History of the Global Positioning System -- 2 Overview of GPS -- 2.1 Basic concept -- 2.2 Space segment -- 2.3 Control segment -- 2.4 User segment -- 3 Reference systems -- 3.1 Introduction -- 3.2 Coordinate systems -- 3.3 Time systems -- 4 Satellite orbits -- 4.1 Introduction -- 4.2 Orbit description -- 4.3 Orbit determination -- 4.4 Orbit dissemination -- 5 Satellite signal -- 5.1 Signal structure -- 5.2 Signal processing -- 6 Observables -- 6.1 Data acquisition -- 6.2 Data combinations -- 6.3 Atmospheric effects -- 6.4 Relativistic effects -- 6.5 Antenna phase center offset and variation -- 6.6 Multipath -- 7 Surveying with GPS -- 7.1 Introduction -- 7.2 Planning a GPS survey -- 7.3 Surveying procedure -- 7.4 In situ data processing -- 7.5 Survey report -- 8 Mathematical models for positioning -- 8.1 Point positioning -- 8.2 Differential positioning -- 8.3 Relative positioning -- 9 Data processing -- 9.1 Data preprocessing -- 9.2 Ambiguity resolution -- 9.3 Adjustment, filtering, and smoothing -- 9.4 Adjustment of mathematical GPS models -- 9.5 Network adjustment -- 9.6 Dilution of Precision -- 9.7 Accuracy measures -- 10 Transformation of GPS results -- 10.1 Introduction -- 10.2 Coordinate transformations -- 10.3 Datum transformations -- 10.4 Combining GPS and terrestrial data -- 11 Software modules -- 11.1 Introduction -- 11.2 Planning -- 11.3 Data transfer -- 11.4 Data processing -- 11.5 Quality control -- 11.6 Network computations -- 11.7 Data base management -- 11.8 Utilities -- 11.9 Flexibility -- 12 Applications of GPS -- 12.1 General uses of GPS -- 12.2 Attitude determination -- 12.3 Airborne GPS for photo-control -- 12.4 Interoperability of GPS -- 12.5 Installation of control networks -- 13 Future of GPS -- 13.1 New application aspects -- 13.2 Improved constellation -- 13.3 Hardware improvements -- 13.4 Software improvements -- 13.5 Conclusion -- References. 330 $aThis book is dedicated to Dr. Benjamin William Remondi for many reasons. The project of writing a Global Positioning System (GPS) book was con­ ceived in April 1988 at a GPS meeting in Darmstadt, Germany. Dr. Remondi discussed with me the need for an additional GPS textbook and suggested a possible joint effort. In 1989, I was willing to commit myself to such a project. Unfortunately, the timing was less than ideal for Dr. Remondi. Therefore, I decided to start the project with other coauthors. Dr. Remondi agreed and indicated his willingness to be a reviewer. I selected Dr. Herbert Lichtenegger, my colleague from the Technical University Graz, Austria, and Dr. James Collins from Rockville, Maryland, U.S.A. In my opinion, the knowledge of the three authors should cover the wide spectrum of GPS. Dr. Lichtenegger is a geodesist with broad experience in both theory and practice. He has specialized his research to geodetic astron­ omy including orbital theory and geodynamical phenomena. Since 1986, Dr. Lichtenegger's main interest is dedicated to GPS. Dr. Collins retired from the U.S. National Geodetic Survey in 1980, where he was the Deputy Director. For the past ten years, he has been deeply involved in using GPS technology with an emphasis on surveying. Dr. Collins was the founder and president of Geo/Hydro Inc. My own background is theoretically oriented. My first chief, Prof. Dr. Peter Meissl, was an excellent theoretician; and my former chief, Prof. Dr.mult. Helmut Moritz, fortunately, still is. 606 $aGeophysics 606 $aGeographic information systems 606 $aGeotechnical engineering 606 $aGeophysics 606 $aGeographical Information System 606 $aGeotechnical Engineering and Applied Earth Sciences 615 0$aGeophysics. 615 0$aGeographic information systems. 615 0$aGeotechnical engineering. 615 14$aGeophysics. 615 24$aGeographical Information System. 615 24$aGeotechnical Engineering and Applied Earth Sciences. 676 $a550 676 $a526.1 700 $aHofmann-Wellenhof$b B.$4aut$4http://id.loc.gov/vocabulary/relators/aut$0472692 702 $aLichtenegger$b Herbert$4aut$4http://id.loc.gov/vocabulary/relators/aut 702 $aCollins$b James$f1936-$4aut$4http://id.loc.gov/vocabulary/relators/aut 801 0$bMiAaPQ 801 1$bMiAaPQ 801 2$bMiAaPQ 906 $aBOOK 912 $a9910958628803321 996 $aGlobal Positioning System$94431967 997 $aUNINA
