The invention concerns a device (10) for measuring one or several navigation parameters in a large-size navigating craft, comprising a parameter sensing and measuring element (11) and at least means for displaying (12) said parameter, connected by electromagnetic waves (13). The element (11) comprises a sensor (20) for measuring the parameter. The value of the measured physical quantity is successively processed by a low frequency processing unit (21), a digitizing unit (22) and a formatted by a microcontroller (23) before being transmitted, in the form of electromagnetic waves, by a transceiver (24). Said waves are received by the display means (12). To enable said reception, said display means comprise a transceiver (31), successively linked to a low frequency filtering and amplifying unit (32), a digitizing unit (33) and a microcontroller (34) which transmits the information to a screen (35). Control units (26, 36) associated with the transceivers (24, 31) enable to reduce the power consumption by setting the device in standby mode when it is not being used.
