摘要

The system comprises a local operating network, which knows their location coordinates, which are disclosed to others. Each local operating network determines the distances to the other local operating network at known locations. The local operating network cooperates in a time division multiplex frame. Each local operating network transfers the assignment of a central location and navigation center.
