Fundamentals of Astrodynamics and Applications, Fourth Edition

Errata

Software and Data

Software routines for the second edition of David Vallado’s book are available for downloading at no cost. They are given in FORTRAN, PASCAL, C, and Ada. Errata for the second edition are also available here. If you have any new errata or comments about the book or software, please E-mail us at bookproject@smad.com.

Organization of the Material

The code is available in several languages, and it is organized roughly according to function. Where feasible, all the time routines are in one file, the math techniques in another, and so forth.

AST2BODY Two-body relations
COMPLX Complex math
CONSTS Constants WGS-84, JGM-2, etc.
ASTDC Differential correction
ASTINTER Interplanetary
ASTIOD Initial orbit determination
ASTMANV Maneuvers
ASTMATH Math
ASTPERT Perturbation
ASTREDUC Reduction of coordinates
ASTTIME Time
ASTUTIL Character operations
SGP4UNIT SGP4 routines
SGP4DC SGP4 Orbit Determination routines

Several data files are needed for some of the files.

NUT85.DAT Nutation coefficients for planetary 85
NUTATION.DAT Nutation coefficients for 106
ATMOSEXP.DAT Sample exponential atmosphere values
TESTASTF.DAT Input for sample test program
SENSOR.DAT Sensor sample values
GEOS1.IN DC input test 1
GEOS2.IN DC input test 2
GEOS5.IN DC input test 5
GEOS1.TXT DC sample output results 1
GEOS2.TXT DC sample output results 2
GEOS5.TXT DC sample output results 5
SGP4-VER.TLE Sample SGP4 test cases

Cross-Reference of Available Functions [Excel spreadsheet]

Within each file there are specific routines to accomplish various operations. Effort has been taken to use similar names and function scopes, although there are some differences based on language features. The SOFTWARE worksheet discusses the specific routines that are available within each larger technical area.

The ALGORITHMS worksheet lists which routines are available (MATLAB).

The EXAMPLES worksheet lists what MATLAB scripts will perform the example exercises in the text. Many are complete, but a few remain to finish all the examples in the text.

The test program is a simple program that executes the input/output operations of each subroutine in that package. There isn’t anything fancy about it. It’s just intended to be a quick check of the answers. The TESTASTF.DAT file contains my results using the codes. Additional work is needed to update this file, but it’s a start.

STK Scenarios from Chapter 6 (5,592,553 bytes)

These scenarios are useful to see the various transfers in 3-D. Other scenarios are in various stages of development.

    Dear Officer.

    I have some questions about perchasing this book.
    I`m a Korean student and live in Republic of Korea(South Korea). If I buy soft or hard cover edition of this book, how long it takes time for delivering?
    or, if I order e-book edition, do I need another e-book reader machine or softwear programs to read the book?
    Please reply me

    Sincerely.

    Yongjun Song

    The author is not quite ready with the software routines at this time. You can visit http://www.celestrak.com/software/vallado-sw.asp for the 3rd edition software routines.

    Dear Sir
    I have purchased a copy of this book, and I am wondering, are the software routines still not available ? Is there any sign of when I can expect them to be available ? Thank you !
    Kind regards
