It is capable of large space, can take full advantage of sparse environments and deal with unknown and dynamic environments, which make it an ideal planner for long range navigation.

This method overcomes the limitations, imposed by low visibility, that are frequent with landmark navigation, and is also suitable for long - distance-range navigation.

Theory, operating features and interface relations of three correction modes for the inertial navigation; Short-Range Radio Navigation, Long-Range Radio Navigation and Visual, are presented.
