Abstract: Object detection and avoidance comprising receiving time-referenced position and state data for vehicles, including a control vehicle, within a specified time-space zone, wherein the vehicles have initial positions within the specified time-space zone.  Terrain data is received for a spatial zone of interest that overlaps the time-space zone. A trajectory window is calculated for each vehicle within the time-space zone, as well as spatial buffer zones around terrain in the spatial zone of interest according to data uncertainty and resolution. A number of homotopically distinct paths are calculated for the control vehicle from a time-referenced initial position to a destination point, wherein the paths keep the control vehicle at least a minimum specified distance from the trajectory windows of other vehicles and the buffer zones of terrain and obstacles. The control vehicle is then routed according to one of the paths.
