Towards a new low cost, simple implementation using embedded
system wirelessNetworking for UAVs
IEEE ANTS 2011
A Unmanned Aerial Vehicle (UAV) is an uncrewed aircraft .
Or
A UAV can be defined as an aircraft flying in auto pilot mode or manual mode with various operation to be performed feeded inside it or to be controlled by GCS.
Definition
UAV classification
● Handheld 2,000 ft (600 m) altitude, about 2 km range ● Close 5,000 ft (1,500 m) altitude, up to 10 km range ● NATO type 10,000 ft (3,000 m) altitude, up to 50 km range ● Tactical 18,000 ft (5,500 m) altitude, about 160 km range ● MALE (medium altitude, long endurance) up to 30,000 ft
(9,000 m) and range over 200 km ● HALE (high altitude, long endurance) over 30,000 ft and
indefinite range ● HYPERSONIC high-speed, supersonic (Mach 1-5) or
hypersonic (Mach 5+) 50,000 ft (15,200 m) or suborbital altitude, range over 200km
● ORBITAL low earth orbit (Mach 25+) ● CIS Lunar Earth-Moon transfer

UAV FUNCTIONS
AMATEUR UAV:-AMATEUR because-1)It will be not be made on industrial scale and will be a research cum project cum hobby.2)It is not powered by a jet or a reciprocating engine.3)Low speed.4)Range of operation is less.5)Cannot carry more weight.6)Camera resolution and accuracy is less.
OUR PROJECT:-
PROJECT SPECIFICATIONS
● An Aero-model with a auto-pilot kit that will be made by me. Presently working on its PCB layout. Kit will include:-
● 1) At-mega128● 2) GPS (GPS receiver with antenna-5V TTL)● 3) Gyroscope (single axis ±300 °/Second Analog Yaw Gyroscope
module)● 4) MMA7361L ±1.5g, ±6g Three axis Low-G Accelerometer Module.● 5) pitot tube (KIT MPXV5004DP)(optional)● 6) Camera and zigbee-pro.● 7)Magnetic compass HMC 6352● 8) Ground control station(HK GCS)
Basic layout of aero-model
● A=auto-pilot control board● B=battery● D=datalink radio modem and antenna● G=GPS receiver● I=accelerometer module● M=motor and
controller● RC receiver and
antenna● S=servo● P=payload
(camera and
video Trx)
PHASES OF PROJECT
● 1st PHASE:- Remote controlled spy.
● 2nd PHASE:-Semi auto-pilot.
● 3rd PHASE:-Fully auto-pilot.
Algorithm
Program where Destination GPS coordinates are
placed
Program where distance and elivation
between 2 coordinates is find out
using HAVERSINE FORMULA
Program where Elivation of the
aeromodel is find out using
GYROSCOPE AND ACCELEROMETER
Programm to take the OUTPUT of GPS in
GGA AND RMC format .
Programm to generate the PWM for the
servo to control the aircraft surface.
Program for PID feedback loop. which will tell us that the
required elivation angle has been covered by
the Aeromodel or not.
Central program which will take I/P
from all other programs and direct
the aeromodel to move through
different coordinates as directed
