2.  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.

4.  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.

7.  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

9.  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.

12.  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

13.  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.

14.  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.

16.  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.

17.  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.
