A situational awareness personal service (SAPS) receives data records from a wide variety of data sources and provides real-time, tailored, situational awareness (SA) information to subscribers. The SA information, which can include course of action recommendations and threat assessments, can be made available and affordable to the general public. Subscribers may view the SA information using commercial off the shelf (COTS) devices, such as laptop computers, smartphones, and existing onboard integrated displays. In one aspect, transportation platforms can provide local observation data, such as radar tracking data, to the SA personal service in exchange for tailored SA information.
