In this paper, we discuss the development of a Global Navigation and Path Planning System suitable for implementation on small, experimental, resource constrained, low cost, RC UAVs. The path planning algorithm generates short and feasible paths using waypoints and trajectories. Obstacle detection and avoidance which are important aspects of local path planning have also been incorporated. The developed path planning algorithm has a shorter computational time when compared with A* algorithm. The output from the path planning algorithm is fed to a GIS system and visually checked using

to ensure that UAV travels in the desired path. A telematics module and a JAUS Standard messaging interface for data exchange between the ground station and UAV has been developed and implemented to transmit and receive data from the UAV.
