A cellular phone based emergency vessel/vehicle location system which includes a navigation unit to determine position and speech synthesis to modulate a transmitter with the emergency message includes a combined dialer and activation detector, in which activation may either be from the cellular phone keypad or from a panic button, a Lojack/hijack sensor, a car theft alarm, airbag deployment, a man down sensor, or other form of remote activation. Upon activation, the activation detector/dialer causes DTMF tones to be generated for telephone number dialing. After dialing, the transmitter for the transceiver is modulated with the emergency message in natural speech. In one embodiment, the dialer and activation detector is actuated from the keypad of the cellular phone, such as 911, *CG, *SP or other predetermined activation code. As a further feature, the number to be dialed is entered into the dialer prior to using the device, or optionally, the number to be dialed can be transmitted to the cellular phone and thence to the dialer when, for instance, a cellular phone is within range of a given cell site.

An emergency location system for transmitting a synthesized voice message including geographic coordinates from one location to another over a cellular phone at the time of an emergency, comprising: a cellular phone at said one location, said cellular phone including a transmitter having a modulation section means for generating DTMF tones corresponding to a telephone number, keypad generating signals for controlling said means for generating DTMF tones to dial telephone numbers, means for transmitting said tones to place a call and a bus for controlling said phone and for coupling remotely generated analog audio signals corresponding to an emergency message the modulation section of said transmitter; means coupled to said bus for providing said remotely generated audio signals to said modulation section said said signals including a predetermined synthesized verbal message including the geographic coordinates of said phone for the modulation thereof; means for providing an emergency message transmission activation signal; and a dialer/activation detector coupled to said bus and electrically interposed between said keypad and said means for generating said DTMF tones and responsive to the provision of said activation signal for locking out said keypad during said emergency message and for generating output signals to capture the operation of said cellular phone so as to control the dialing operation thereof from said dialer/activation detector only during said emergency message transmission, and relinquishing said control after said emergency message has been transmitted, said dialer/activation detector including means for causing said DTMF tone generating means to provide tones for dialing predetermined telephone number by interrupting portion of said keypad during said emergency message, thus effectuate a substitution of said dial at output signals said keypad generated signals during said emergency message and for actuating said synthesized verbal message providing means to modulate said transmitter section with said emergency message.
