An omega, loran or satellite navigation receiver is provided with a speech synthesizer coupled to its latitude/longitude output which is in turn coupled to a transmitter which transmits the latitude and longitude along with a "mayday" indication on an emergency channel when an emergency button is depressed on the unit. The emergency button turns the power on for the navigation unit and bypasses all functions except those relating to the production of a lat./lon. signal. The emergency button also activates the synthesizer after determining that the navigation unit has obtained lock. Upon the obtaining of lock a repeat timer produces repeated dump pulses to the speech synthesizer which modulates the transmitter to transmit the "mayday" indication plus an indication of the latitude and longitude of the vessel. As an option, the vessel name, type and color may be entered into a memory for the speech synthesizer so that the identity of the vessel and its type and color may be ascertained. As an additional feature the unit is provided with a receiver tuned to a special channel utilized by the Coast Guard or other authorities to disable the transmitter remotely. A manual disable from within the vessel is also provided. In one embodiment the same antenna is utilized for the navigation unit, the transmitter and the receiver, whereas in another embodiment the navigation unit is placed in stand-by during the transmit cycle so that its latitude and longitude are not affected by the emergency transmission.
