A low cost fully autonomous GPS (Global Positioning System) based quad copter for disaster management

With the advent of real life applications in the fields of public safety like disaster management and defence, Quad copter is becoming more and more popular. Quad copter does not require any traffic signal; it can fly in the sky like bird and it can go anywhere as per requirement. This feature has boosted up the popularity of Quad copter in the community. Now a day's more and more fields get dependent on Quad copter, therefore the system needs to be more robust and less expensive. For example, in defence field security is the major issue, while in Disaster management time public safety is the major issue. The paper proposes a low cost, secure (as it has Global Positioning System installed in it, so it can hold at any position getting proper instruction by operator) and autonomous model for a Quad copter. This quadcopter can be controlled manually via transmitter (minimum 4 channel).
