Abstract
A system and method for monitoring a spatial position of a mobile transmitter is provided. In particular, the mobile transmitter may be attached to or included in an object of interest. By analyzing the signal strengths of radio frequency signals emitted by the transmitter, a spatial position of the mobile transmitter can be determined, and it is possible to detect whether or not the spatial position of the mobile transmitter is outside an allowable area. By applying the monitoring of the spatial position to a radio frequency system on a vessel, a reliable man-over-board detection can be achieved.
Claims27
A system for monitoring a spatial position of a mobile transmitter, the system comprising:
- a number of at least two base stations for receiving at each base station a radio frequency signal emitted by the mobile transmitter,
- wherein at least one of the number of the at least two base stations is configured to establish a wireless data communication with the mobile transmitter and the at least one base station is connected to a further device of a communication network, and
- wherein the mobile transmitter is configured to establish a wireless communication link to the further device of the communication network via the at least one base station;
- and
- a processing unit for obtaining signal strength of the radio frequency signal received by the number of the at least two base stations, computing a spatial position of the mobile transmitter based on the signal strengths of the received radio frequency signals, determining whether or not the computed spatial position of the mobile transmitter is outside a predetermined spatial area, and generating an alert indication if the computed spatial position of the mobile transmitter is outside the predetermined spatial area,
- wherein the signal strength of the radio frequency signals obtained by the processing unit comprise a signal strength of the at least one base station which is connected to a further device of a communication network.
