Space Mechanics
5 self-contained study topics — notes, diagrams, formulas, and worked examples for exams and GATE.
Topics
- Orbital MechanicsOrbital mechanics predicts satellite velocity, period, and geometry under central gravity using Bate et al. fundamentals.
- Two Body ProblemThe two-body problem gives exact conic trajectories when only mutual point-mass gravity acts.
- Orbit Transfer ManeuversOrbit-transfer maneuvers compute minimum delta-V trajectories between orbital states, especially Hohmann transfer cases.
- Attitude Dynamics and ControlAttitude dynamics relates applied torque to angular-motion evolution and guides controller plus actuator sizing.
- Spacecraft PerturbationsSpacecraft perturbations quantify long-term orbital-element drift caused by J2, drag, SRP, and third-body gravity.
