CASPER

C++ Aided, SPICE-based, Propagation for Ephemeris model Results (name WIP).

A C++ N-body propagation tool that is wrapped with pybind11 to be called from Python.

Uses the Boost.Odeint RK78 integrator

Very much a work in progress

TODO

• choose whether to propagate the STM or not depending on the size of the initial condition vector
• throw exceptions if the initial condition vector is not a 6-vector or a 42-vector
• implement event finding
• add options to specify what the central body and perturbing bodies are from Python
• Use fewer time steps if integrating for corrections vs integrating for detailed state history and/or plotting
• Implement some sort of a smart Spice time class so I can pass it an epoch string or an ET

Notes to make this work

• Need to have a folder with the meta-kernel saved in it with the name "generic_kernels.tm" assigned to an environment variable "KERNEL_PATH"
• Need to have your python installation path added to the "CPLUS_INCLUDE_PATH" environment variable
• boost needs to be installed
