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.
