Maritime Model –
Mobility Model
•Intra-task force mobility
•Based on the Nomadic Community model where the individual nodes of each task group move randomly within 3 nm of their base position
•Links fail when they exceed 18 nm.
•Inter-task force mobility
•The two task groups begin 18 nm away from each other (at the closest point) and at a random arrival angle.
•The first task group then approaches the other steadily at a relative speed of 30 knots (nm/hour) on a set heading evenly distributed from this trajectory angle of -45° to +45°
A - Angle of arrival
T - Angle of trajectory
