Which GMD sensor is classified as Space Based?

• A. DSP
• B. AN/TPY-2
• C. Ground Based
• D. Aegis

Answer: (A)

The correct choice is the Defense Support Program (DSP) satellite. DSP is classified as a space-based sensor utilized primarily for missile launch detection due to its infrared sensing capabilities. This satellite constellation is designed to detect the heat signature of missile launches, providing critical early warning capabilities for the integrated missile defense system. Its deployment in space allows for a wide area of coverage and the ability to detect missile launches across the globe, which is a fundamental component of the space-based sensor architecture for missile defense. In contrast, the other options represent different types of missile defense systems and sensor technologies. The AN/TPY-2 is a transportable ground-based radar system that provides tracking information but is not space-based. Ground-based sensors, as the name suggests, are also located on the ground and are not classified as space-based. Aegis primarily refers to a ship-based system that utilizes radar for tracking and engaging targets; therefore, it also does not fall under the category of space-based sensors.
