Abstract: A system, methods, and apparatus for dual antenna transfer switching are disclosed. In an example embodiment, a dual antenna system includes antennas, antenna control units, a transfer switch, and a modem. For example, the transfer switch may transfer a connection between antennas based on changing satellite visibility, upon entering a preprogrammed blockage zone or an unexpected loss of satellite visibility. The transfer switch may receive GPS data from an external GPS unit and/or the antenna control units and buffer the GPS data to a modem. The transfer switch may provide a modem receive-lock signal to retarget a line of sight. The transfer switch may transfer the connection between the antennas based on satellite visibility including signal reception quality and/or a modem receive-lock status. The transfer switch may, based on a difference in antenna uplink transmission power, attenuate a higher power antenna to be balanced with a lower power antenna.

Abstract: Systems and procedures for tracking the locations of passengers on a vessel are provided. Example systems may include a portable tag configured to be assigned to a passenger, the tag encoded with a tag identifier; a plurality of tag readers configured to be positioned at predetermined locations on a vessel, each tag reader configured to read the tag identifier of the tag when the tag reader receives a signal from the tag; a tracking component configured to communicate with the tag readers, the tracking component configured to receive, from a detecting tag reader, an indication that the signal has been received from the tag, the tracking component configured to determine a detected location of the tag based at least in part on the predetermined location of the detecting tag reader; and a notification component configured to send towards a user device, a notification including the detected location.

Abstract: A fall detection and recovery system includes cameras positioned around a perimeter of a vessel. The system analyzes video from the cameras to detect a falling object from the vessel and records a geolocation of the vessel at a time of falling of the object. The system applies environmental readings to evolve a recovery location for the falling object from the time of falling to a present time.
