What is a Rocket?
A rocket is a missile,
spacecraft, aircraft or
other vehicle whichobtains thrust by ejecting a
jet of fast moving fluid
exhaust from a rocket
engine. Chemical rockets
create their exhaust by the
combustion of rocket
propellant. ...

What is a missile?A rocket carrying a warhead
of conventional or nuclear
explosives; may be ballistic or directed by
remote control projectile.

A weapon that is forcibly
thrown or projected at a

propelled.

Difference between
Missile & RocketA missile is any weapon which flies toward its target, it
could be anything from a rock that you pick up off the
ground and throw at an enemy, to a spear, an arrow, a bullet, up to a multi-staged rocket carrying multiple
MIRV-type nuclear weapons.
A rocket, of course, is simply a non-air-breathing object
which is propelled by shooting a stream of gases out
behind it.

Guided Missile Guided Missiles, usually containing
conventional or nuclear explosives, guided
in flight towards a target either by remote
control or by internal mechanisms. Guided
missiles vary widely in size and type,
ranging from large strategic ballisticmissiles with nuclear warheads to small,
portable rockets carried by foot soldiers.

POWER SOURCE1) SELF CONTAINED R OCKET MOTORS: It
contains a motor fan which force it by the air to proceed.It is less efficient & used in the past era.
2) AIR BREATHING JET ENGINE¶S: In this type of power source the combustion chamber in which the fuel burns is called the motor When the fuel in a solid- propellant rocket is ignited, the gases formed duringcombustion are forced out the nozzle and the rocketmoves forward. The fuel is called the grain and is oftenformed with a hollow core for longer burning times.

INERTIAL GUIDANCE
SYSTEM (INERTIAL
PLATFORM)
An inertial navigation system measures the
position and altitude of a vehicle bymeasuring the accelerations and rotationsapplied to the system's inertial frame. Itconsists of an inertial navigation system
combined with control mechanisms,allowing the path of a vehicle to becontrolled according to the positiondetermined by the inertial navigation system

Guidance system
A guidance system is a device or group of
devices used to navigate a ship, aircraft,
missile, rocket, satellite, or other craft.Typically this refers to a system that
navigates without direct or continuous
human control. Systems that are intended to
have a high degree of human interaction are
usually referred to as a navigational system

BEAM RIDING Beam-riding guidance leads a missile to its
target by means of radar or a laser beam. It
is one of the simplest forms of radar or laser guidance.
The main use of this kind of system is to
destroy airplanes or tanks

missile or other projectile or vehicle to a
target by means of a laser beam.

Active radar homing is a type of missileguidance where a guided missile contains aradar transceiver and the electronicsnecessary for it to find and track its target
autonomously.

A wire-guided
missile is amissile guided by
signals sent to it
via thin wires
reeled out during
flight.

INFRARED HOMING
Infra-red homing refers to a guidance
system which uses the infra-red light
emissions of a target to track it. Missiles
which use infra-red seeking are oftenreferred to as "heat-seekers". Infra-red is
just below the visible spectrum of light and
is radiated mostly by hot bodies.

Long R ange Navigation (LORAN)
This was the predecessor of GPS and was(and to an extent still is) used primarily in
commercial sea transportation. The system
works by triangulating the ship's position
based on directional reference to known
transmitters.

Global Positioning System (GPS)
This system of satellites provides extremelyaccurate position information. Thereceiver's position is triangulated usingsatellites in known orbits. Commercialreceivers are limited in how accurately they
may provide position data, as well as themaximum velocity at which they mayoperate. This is to prevent their use inmanufacturing weapons.

Optical guidance
Guided missiles use stored images of the terrainthey are to fly over and an external sensor to track their current position. This guidance system wasextremely expensive and not suitable for use insmall payload operations. These were used oncruise missiles before the advent of GPS, which is both cheaper and more accurate. Devices thatimplement optical guidance incur high costs because of the high on-board processingrequirements needed to check the current locationagainst the course data
