Common Basilisk Support Files
The folder src/architecture/utilities contains a number of C code support libraries that simplify the mathematics of writing Basilisk modules.  This page highlights some common libraries used.
- astroConstants.h
- astroConstants contains a range of orbital mechanics related variable definition. 
- avsEigenMRP.h
- avsEigenMRP provides MRP capabilities to the Intel Eigen library. 
- avsEigenSupport.h
- avsEigenSupport provides a range of helper function to convert between C array variables and Intel Eigen library vectors and matrices. 
- discretize.h
- discretize provides functions to discretize a real number. 
- gauss_markov.h
- gauss_markov provides functions to apply a second-order bounded Gauss-Markov random walk on top of an upper level process. 
- geodeticConversion.h
- geodeticConversion provides a collection of functions to convert to and from planet centered frames. 
- keplerianOrbit.h
- keplerianOrbit class represents an elliptical orbit and provides a coherent set of common outputs such as position and velocity, orbital period, semi-parameter, etc. It uses the utility orbitalMotion to do orbital element to position and velocity conversion. 
- linearAlgebra.h
- linearAlgebra provides a collection of functions perfrom 2D, 3D, 4D and N-dimensional matrix math in C 
- macroDefinitions.h
- macroDefinitions provides a collection of convenient macro definitions 
- orbitalMotion.h
- orbitalMotion provides a collection of orbital mechanics related function. 
- rigidBodyKinematics.h
- RigidBodyKinematics provides a collection of rigid body kinematics transformations. This includes functions to map between a range of attitude coordinates. 
- saturate.h
- saturate is used to saturate an output variable 
- signalCondition.h
- signalCondition provides provides a low-pass filter to an output variable 
- simDefinitions.h
- simDefinitions provides common simulation related definition such as default epoch states, etc.
