Abstract :
A problem of concern to ships operating with one another is the gridlock, or relative navigation, problem. The method developed here uses a linear combination of mutually exchanged observations of relative position to form new and better estimates of these positions. Chief advantage of the method is the reduction of gridlock errors it provides. The primary disadvantage is that it is limited by the range of the local sensors on board each ship.
