Overview

The 'Location and Time Data Source' provides accurate position information. While a Global Positioning System (GPS) Receiver is the most common implementation, this physical object represents any technology that provides a position fix in three dimensions and time with sufficient accuracy.

This physical object does not have any functionality defined in ARC-IT, as it exists outside the system functional boundary.

This physical object is included in the following Service Packages:

Triples
