Which of the following technologies originated from military design?

• A. Pill-cam (cancer detection)
• B. Epipen
• C. GPS
• D. Penicillin

Answer: (C)

Technology often moves from military research into everyday use when precision, reliability, and robustness are the driving needs. Global Positioning System fits this pattern perfectly. It was developed by the U.S. Department of Defense in the 1970s to provide accurate, all‑weather navigation for military operations, using a constellation of satellites and highly synchronized timing. The design prioritizes dependable signals and timing integrity in challenging environments, which are exactly the conditions the military required. Once the system matured, civilian applications exploded—car navigation, smartphones, logistics, disaster response, and timekeeping—demonstrating how a military-led project can transform everyday life.

The other items come from medical or pharmaceutical fields rather than military design: a capsule camera for internal imaging and cancer detection; an epinephrine auto-injector for allergic emergencies; and penicillin, discovered through microbiology and chemistry.
