StatODFinal
Final project for ASEN 6020 Statistical Orbit Determination. Uses Unscented Kalman Filter to estimate spacecraft state with unknown perturbations.
ddp_se_halo
Master's Thesis: single-phase hybrid differential dynamic programming applied to low-thrust Sun-Earth L1 halo to L2 halo orbit transfers.
indirect_EM_lyap
Indirect optimization for energy-optimal Lyapunov-to-Lyapunov transfer using heteroclinic connection as initial guess.
initial_guess_sel1l2_halo
Master's Thesis: initial guess construction for Sun-Earth L1-L2 Halo transfer for use in DDP. Uses multiple-shooting with low-thrust enabled nodes.
AttitudeControlFinal
Final project for ASEN 5010 Spacecraft Attitude Dynamics and Control. Models the use of magnetorquers (torque rods) to control attitude of spacecraft in Earth orbit. Compares two different control laws.
ISEE3HaloOrbit
Final project for ASEN 5050 Spaceflight Dynamics. Uses differential correction to recreate the ISEE-3 spacecraft orbit around the Sun-Earth L1 Lagrange point.
lambertSolver
Lambert's problem solver.
hohmannTest
Learning c++. Uses Boost library's ODE integration libraries to compute and propagate Hohmann transfer orbit.
Jupiter_SPH
Final project for Ph235.
matplotlib-cpp
Extremely simple yet powerful header-only C++ plotting library built on the popular matplotlib
