sat_code

C/C++ code for the SGP4/SDP4 satellite motion model, and for manipulating TLEs (Two-Line Elements). Full details at http://www.projectpluto.com/sat_code.htm.

The only dependency is on the lunar (basic astronomical ephemeris/time functions) library. Make and make install that library before attempting to build this code.

On Linux, run make to build the library and various test executables. (You can also do this with MinGW under Windows.) In Linux, you can then run make install to put libraries in /usr/local/lib and some include files in /usr/local/include. (You will probably have to make that sudo make install.) For BSD, and probably OS/X, run gmake CLANG=Y (GNU make, with the clang compiler), then sudo gmake install.

On Windows, run nmake -f msvc.mak with MSVC++. Optionally, add -BITS_32=Y for 32-bit code.
