Infant Voice Over Internet Protocol Takes Grown-up Steps Into Space

February 2000
By Sharon Berry

Researchers are adapting voice over Internet protocol technology to establish communication between Earth and spacecraft, satellites, and, perhaps someday, other planets. Using modified commercial approaches, scientists will design space-based and mobile Internet standards that provide access to science mission data and interactive communication with inhabited and uninhabited spacecraft. These technologies also will become the connection to a future Mars-based communications infrastructure.

Cyberspace Situational Awareness Demands Mimic Traditional Command Requirements

February 2000
By Tim Bass

Future military cyberspace security may require next-generation network management and intrusion detection systems that combine both short-term sensor information and long-term knowledge databases to provide decision-support systems and cyberspace command and control. Sophisticated computer hardware and software would identify a myriad of objects against a noise-saturated environment. Cyberspace command and control systems would track the objects, calculate the velocity, estimate the projected threats, and furnish other critical decision-support functions.

A manportable sensor capable of detecting troops and vehicles up to 100 meters away offers commanders a variety of choices for defensive and surveillance operations. Consisting of a microwave Doppler radar unit and a passive infrared detector, the activated device transmits a message to a sentry who is equipped with a pager display that indicates the type of target and the direction it is moving.
