6.8.1.3: Process Personal Portable Device Location Data

This process shall provide the traveler's current location to other personal traveler processes. It shall receive the precise location from a Location and Time Data Source Terminator. The terminator may base its data on one or more sources of position data such as GPS or DGPS, and may refine its calculations using techniques such as map matching, dead reckoning, etc. The process shall provide the location to other processes for use in autonomous and dynamic route guidance. This location should be as precise as is practical within cost and technology constraints. It is intended for use by traveler personal navigation and guidance systems, as well as emergency notification systems.

This process is associated with the Personal Information Device physical object.
