1. An autonomous interrogatable information and position device, comprising: a satellite communications device for sending and receiving digital voice and data messages to and from a satellite communications network; a geo-location device for receiving positioning signals and for determining a positional location of said autonomous interrogatable information and position device without allowing external detection of said positional location; an input port, said input port configured to allow coupling of said autonomous interrogatable information and position device to external local site sensors to obtain external local site sensor data; voice input means; a voice message formatter for converting a voice signal received from said voice input means into a digital voice message for transmission to said satellite communications network via said satellite communications device; and a control processor coupled to said satellite communication device, said geo-location device, said voice input means, and said input port, said control processing being operable to monitor said positional location and said external local site sensor data, and being responsive to an interrogation message received by said satellite communications device to generate a response message in response to said interrogation message for transmittal to said satellite communications network via said satellite communications device.
