Abstract: A method for establishing a path from a launch point to a destination point that can include multiple way points while avoiding landmass areas. Launch points and destination points can lie outside or inside the particular landmass areas. The method includes steps for defining tangents path areas to be avoided, extending those tangents to define way points and testing the individual way points to assure conformance to various conditions and constraints. A subset of paths are optimized. The shortest of the optimized paths becomes a final path.

Abstract: A process for generating fly-around boundaries for use by projectiles such as missiles or the like which facilitates the steps of providing original cartographic data representative of at least one geographical position on a landmass and providing a predetermined value for the spacing of a fly-around boundary from the geographical position; digitizing the original data and creating a landmass model in a format which includes latitudinal and longitudinal coordinates of the geographical position; inputting the digitized data and the predetermined value into a data analyzer; generating new data representative of the fly-around boundary using the data analyzer based on the predetermined value and the land mass model, preferably by offsetting fly-around segments from the landmass model a distance equal to the predetermined value; and providing a navigational control for receiving the new data and using the new data for controlling the flight path of the missile along the boundary.
