Version: 1.0.1
Release Date: November 16, 2020

READ DOCUMENTATION BEFORE USE.

A useful source is the Software User Manual and other documentation in the lab repo.

• You will need GFortran to execute the code contained in this repo. Follow these instructions to install it in your environment. A stable recommended release is recommended (at least 8.1.0)
• If you are working on MacOS, you'll have to link it manually

  ln -s /usr/local/Cellar/gcc/8.2.0/lib/gcc/8/libgfortran.* /usr/local/lib

• We are leveraging the GNU functionalities of make with a version >4. To install it on make you can do brew install homebrew/core/make and use it with calling gmake instead of make. make will remain with the default older version on mac 3.81 and gmake will be the newer version.

make test

It will print out your compiler information. You can put your own compiler as such:

fortranCompiler=myFortranCompiler gplusCompiler=myg++Compiler gccCompiler=myGccCompiler make test

Otherwise there are default compilers defined in the Makefile.

This should create in the output folder the files that should be equal to the reference files

make clean

This will clean the test folder of the created .mod, .o and executable files.

The two compiled executable files can then be used freely by the user to run D-SPOSE according to the input text files in the intput foler.

The first converts the Two-Line Element contained in TLE.txt into an osculating position and velocity vector contained in initial_conditions.txt using the SGP4 algorithm:

./tle2rv_exec

The second runs the coupled orbit-attitude propagator using the parameters in the other input files in the intput foler and outputs the information in the output folder:

./dspose_exec
