Position Corrections Source --> Personal:
position corrections

Definitions

position corrections (Information Flow): Ground based reference station positioning corrections

Position Corrections Source (Source Physical Object): The 'Position Corrections Source' represents the external source of land-based position corrections that augment satellite-provided (e.g., GPS) positioning data.

Personal (Destination Physical Object): The 'Personal' physical object is used to model core capabilities that are common to more than one physical object in the 'Personal' class. It provides the general executive, management, and utility functions that may be shared by different types of personal devices.

    InteroperabilityDescription
    LocalIn cases where an interface is normally encapsulated by a single stakeholder, interoperability is still desirable, but the motive is vendor independence and the efficiencies and choices that an open standards-based interface provides.

    Basis This data is intentionally transmitted to everyone via a broadcast. It can also be determined via other visual indicators. An incorrect location corrections message, could lead to a false warning or lack of warning. A lack of warning can have obvious catastrophic consequences, while a false warning could lead to users ignoring warnings due to perceived inaccuracy. Given that this triple may apply to highly dynamic environments (such as work zones), its accuracy is paramount, and thus if sent, must have HIGH integrity. If locations corrections are not delivered, catastrophic consequences could result from incorrect locations data on the device that should have received the corrections. DISC: HIGH is a tall barrier for this flow.
