1

Basic Concepts: The solar system, comets and meteors, Kepler’s laws

and Newton’s law of gravitation, concept of celestial sphere, vernal

equinox, ecliptic. Coordinate systems- ECI system, geographic

coordinate system, azimuth-elevation coordinate system, ecliptic system,

Time systems- sidereal time, mean solar time, Julian date, universal time,

ephemeris time.

2

Two-Body and Restricted Three Body Problems : N-body problem,

two- body problem- simplifying assumptions. Equations of relative

motion. Constants of the motion- conservation of angular momentum,

Trajectory equation, elliptical orbit- geometry of the ellipse, period of an

elliptical orbit, circular orbit, parabolic orbit, hyperbolic orbit. Geometry

of the hyperbola, hyperbolic excess speed. Orbital elements.

Introduction, equations of motion, Lagrangian points, stability of the

Lagrangian points, Jacobi’s integral, accessible regions.

10

3 Basic Orbital Maneuvres and Orbit Perturbations : Low altitude earth

orbits- effect of orbital altitude on satellite life times, direct ascent to 10

orbit, perturbations of low earth orbits due to the oblate shape of the

Earth. High altitude earth orbits- the synchronous satellite, launching a

high altitude satellite. In-plane orbit changes- adjustment of perigee and

apogee height, Hohmann transfer, general coplanar transfer between

circular orbits, Out-of plane orbit changes-simple plane change.

General overview of orbit perturbations, Earth gravity harmonics,

lunisolar gravitational attractions, solar radiation pressure effects,

atmospheric drag effects, tidal friction effects and mutual gravitational

attraction. earth’s oblateness (J2) effects, critical inclination. Sun-

synchronous orbits, J3 effects and frozen orbits, Earth’s triaxiality effects

and east-west station keeping.

4

Ballistic Missile Trajectories: The general ballistic missile problem-

geometry of the trajectory, free flight range equations, flight path angle

equation, maximum range trajectory, time of free flight. Effect of

launching errors on range- effect of lateral displacement of the burnout

point, cross range error du e to incorrect launch azimuth, effect of down

range displacement of the burnout point, errors in burn-out flight-path

angle, down range errors caused by incorrect burnout height and in

correct speed at burnout. The effect of earth rotation- compensating for

the initial velocity of missile due to earth rotation, compensating for

movement of the target due to earth rotation.

5

Interplanetary Trajectories: Patched-conic approximation-

heliocentric transfer orbit, phase angle at departure, escape from the

earth’s sphere of influence, arrival at the target planet, effective collision

cross-section. Locating the planets- launch opportunity, synodic period,

trajectory type and class, ephemeris calculations, Non-coplanar

interplanetary trajectories, Gravity- assist maneuver. Fast interplanetary

trajectories.
