Catalogue of functionalities and elementary individual functions for the identified tasks 
The following sections contain the catalogue of functionalities and functions identified for the process of 
integrated navigation. The structure of the catalogue follows the process tasks defined in Section 1. 
The format of the tables of functionalities and functions listed in the following differs according to the 
depth of classification of the tasks concerned. 
The tables contain the following columns, depending on the depth of classification of the particular func 
tionalities considered: 
• Abstract functionalities of classification level 1. This level is introduced in the case 
of complex functionalities. From the functionalities of this level it is not yet possible to 
directly derive elementary individual functions. 
• Detailed functionalities of level 2. This is the “lowesf level of functionalities for the 
respective task. The analysis of these functionalities leads directly to elementary indi 
vidual functions. 
• Function. This column contains the elementary individual functions of the particular 
functionality listed for the “detailed classification level (see above). 
• Input and output information. For each function are listed the necessary input in 
formation and the supplied output information.
