Abstract
A method of warning target objects (TOs) of an approaching reference object (RO) includes receiving, by a back-situation awareness function (BSAF) application, RO notification (RON) messages from the RO containing RO related state information, generating, by the BSAF application, a geo-sector (GS) area including a number of GS segments between a current location of the RO and a destination object (DO) specifying a destination location of the RO, calculating, by the BSAF application, for each of the GS segments of the GS area an expected time of arrival (ETA) of the RO at a respective one of the GS segments, and disseminating the calculated GS segment specific ETA values to the TOs.

A method of warning target objects (TOs) of an approaching reference object (RO), the method comprising:
- receiving, by a back-situation awareness function (BSAF) application, RO notification (RON) messages from the RO containing RO related state information,
- generating, by the BSAF application, a geo-sector (GS) area including a number of GS segments between a current location of the RO and a destination object (DO) specifying a destination location of the RO,
- calculating, by the BSAF application, for each of the GS segments of the GS area an expected time of arrival (ETA) of the RO at a respective one of the GS segments, and
- disseminating the calculated GS segment specific ETA values to the TOs.
A system for warning target objects (TOs) of an approaching reference object (RO), the system comprising a back situation awareness function (BSAF) application configured to:
- receive RO notification (RON) messages from the RO containing RO related state information,
- generate a geo-sector (GS) area including a number GS segments between a current location of the RO and a destination object (DO) specifying a destination location of the RO,
- calculate for each of the GS segments of the GS area an expected time of arrival (ETA) of the RO at the respective one of the GS segments, and
- provide for the dissemination of the calculated GS segment specific ETA values to the TOs.
