 Micro air vehicles is an unmanned air vehicle
that has size restrictions and autonomous.
 These are small light weight , and autonomous
that can fix in a back pack used to perform
tasks in a near earth environment.
 Micro air vehicle is small enough to fit in our
hand , and operating range of several
kilometers and transmit detailed pictures back
to portable base station.

 Size should be less than 15cms, To the human
eye, an MAV in flight would resemble a small
bird.
 The projected MAV airspeed of 10 to 15 m/sec
which is below the minimum velocity of most
radars.
 Operating in an approximate radius of 600
metres from the launch point, μAVs are used to
acquire real-time visual information for a wide
range of applications.

 The simplest design is an MAV that can remain
within the line of sight of a small base station.
 Base station tracks the vehicle, maintains the
communications link, and performs navigation
calculations.
 For Navigation GPS is used since it can be
available in small components.
 Alternatively, the MAV might be able to perch,
or fasten itself to a fixed object, or turn into a
crawler for local sensing

 Size comparison of existing unmanned air
vehicles (UAVs) and proposed MAVs.
 The profile of a soldier scale, represents six feet.
 The smallest known UAV for defense
applications currently flying is the Naval
Research Laboratory Self-Navigating Drone
Expandable/Recoverable (SENDER), which
has a 1.2-m wingspan.
 The proposed MAVshave wingspans of 7.4 cm
and 15 cm, or 3 and 6 in.

 Model of Lincoln Laboratory concept of the
smallest possible MAV (7.4-cm wingspan) with
a visible imager for reconnaissance missions.
This bottom view of the model shows the
down looking camera port in the nose

 If we use an electric motor with 60% efficiency,
the baseline electrical power is 4.2 W.
 These values, however, provide only enough
power for level flight, and they must be
doubled so that the MAV can turn, climb, and
fly in gusty air.
 To produce this power, we considered a
variety of efficient and lightweight propulsion
systems , micro turbines including electric
motors powered by batteries.

 MAV flight-control system. Flight control
requires sensors that measure motion (roll,
pitch, and yaw) of theMAV, and aerodynamic
control inputs that stabilize and maneuver the
MAV in wind gusts and turbulence.

 From baseline, communications system also
tracks the position of the MAV from the
ground , Using the Ka-band for
communications provides a good compromise
of antenna size, antenna beam width and
propagation losses.
 The 21-GHz band was chosen because of its
availability and the existence of circuit
technologies for satellite communications in
that band.

 An MAV could provide significant new
capabilities to a wide range of users.
 Several MAVs and a base station could be
transported and operated by a single
individual, providing real-time data directly to
the local user.
 A variety of vehicle configurations and sensors
could be used for many possible missions.
 Following is the image taken by MAV

Disaster Management
 Fire.
 Earth quakes.
 Gas leakage.
Commercial
 Television.
 Photography.
Defense and security.
 Surveillance and reconnaissance.
 Explosive and Mine detection.
 Counter terrorism.
 Bio and Harmful gases like NOVA 6 detection.
