In recent years, UAVs have been increasingly used in a wide range of applications to eliminate the human presence in a dull, dangerous, dirty missions. For instance, in military ISR missions, Maritime arena missions, Search and Rescue missions, environmental monitoring, battle damage assessment and so on. The potential advantages of UAVs over piloted missions include reducing the cost, avoiding loss of pilots, and increased maneuverability. Their ability to navigate over large areas faster than land vehicles and their privileged aerial view adds to one of their main uses in monitoring and surveillance. A UAV in these mission must provide coverage of area of interest and investigate events of interested waypoints, so central for the development of UAV technology are the algorithms for path planning and exhaustive search pattern. It is paramount to find the optimal path for manoeuvres of a UAV, since the endurance and fuel consumed play a role in dictating the flight path. Thus, it can be expected that the performance of a UAV may greatly benefit from the development of a path planning and search pattern algorithms This report has been divided in two parts: where first part discusses about the UAV path planning while the second part discusses about Search pattern algorithms. The goal of UAV path planning is to find the shortest route based on generalisation of the Travelling Salesman Problem. In this thesis, Genetic Algorithm is used to solve Travelling Salesman Problem. Raster search algorithm and Expanding square search are the two search pattern algorithm used in this thesis for Search and Rescue missions. In this project AGI’s flagship product STK was used for visualizing and analysing the path planning and search pattern algorithm. A custom engine application was built using the API’s available with STK, which can be used on any system that has STK installed in it. The result of this thesis provides a pre-mission analysis capability which can be extended to real time analysis by adding few operational constraints such as weather conditions, variable speed of the UAV etc…
