Astro-satpass is Copyright (C) 2005-2018 by Thomas R. Wyant, III DESCRIPTION This package contains classes needed to predict satellite visibility, and a demonstration application (satpass) that makes use of these classes. The classes themselves are: Astro::Coord::ECI - superclass (coordinate transforms) Astro::Coord::ECI::Moon - Predict location of the Moon. Astro::Coord::ECI::Star - Predict location of a star. Astro::Coord::ECI::Sun - Predict location of the Sun. Astro::Coord::ECI::TLE - Predict location of a satellite. Astro::Coord::ECI::TLE::Set - Aggregation of TLEs, with ability to use the correct TLE depending on time. Astro::Coord::ECI::Utils - Constants and utility subroutines. The following has been moved to its own package: Astro::Coord::ECI::TLE::Iridium - Subclass of TLE, with the ability to predict flares. INSTALLATION Most Perl users will want to install using their favorite of 'cpan', 'cpanm', or 'cpanp'. For any of these, installing Astro::Coord::ECI gets you everything. ActivePerl users who use ActiveState's 'ppi' should install Astro-satpass. If for some reason neither of these works for you, you can download the distribution and expand it using something like tar -xzf Astro-satpass-9.999.tar.gz Users of MSWin32 (and perhaps other operating systems) may need to convert the line endings in the expanded files from Unix to their native system before proceeding. Then, issue one of the following two incantations: perl Makefile.PL make make test sudo make install or perl Build.PL ./Build ./Build test sudo ./Build install You should substitute the appropriate program name for 'make', eg nmake (typically) under MSWin32, or mms or mmk under VMS. See ftp://ftp.microsoft.com/Softlib/MSLFILES/nmake15.exe for a copy of nmake for MSWin32 if you need it. Unix users may want to use 'su' rather than 'sudo' for the install. Non-unix users may need to be logged in to an administrative or otherwise privileged accout, and turn on privileges (if applicable) for the install. Of course, since it's pure Perl, you can just expand the kit and drop the .pm files into the Astro/Coord/ECI directory (creating it if necessary) in the appropriate place in your @INC directories.
