This paper presents ideas for creating and developing Interactive Navigational Structures (IANS) by using satellite systems. The author of the present paper introduced the concept of IANS into the literature in 2004 (Czaplewski, 2004). The paper presents the possibility of adapting the contemporary methods of robust estimation that are used in geodesy for the purpose of performing selected marine navigation tasks. IANS utilise modern M-estimation methods. Interactive structures can assist human beings in carrying out special tasks at sea, for example, in identifying objects at sea and on land without the need to approach them. Moreover, these structures can also be used in the process of navigation carried out by underwater vehicles or unmanned watercraft. This paper presents the mathematical methods that are essential for creating IANS. The theoretical assumptions are illustrated with an example of how IANS can be used while performing a typical navigation task. The paper closes with information about research studies which deal with the practical aspects of using this set of mathematical methods.
