Two sections near the end were added; one on Augmentation systems, and one on Global Navigation Systems. General updating: I have updated the text in quite a few places, such as eliminating the word “recently” which is no longer really recently. Also the Conclusion has been appropriately reworded. Added one reference [25]. Living Reviews applied its current layout to this revision.
