The term VULOS is associated with which concept?

• A. VHF/UHF Line of Site
• B. Very Useful Link Operation System
• C. Vector Ultra Low Orbit System
• D. Visual Uplink Local Oscillator Subsystem

Answer: (A)

VULOS refers to VHF/UHF Line Of Sight communication. This describes radio links that rely on a direct, unobstructed path between transmitter and receiver on the VHF or UHF bands. Range is limited by the radio horizon, which depends on antenna heights and terrain, so signals travel in mostly straight lines and require clear terrain or elevation to maintain the link. The other expansions aren’t standard terms used in this context, so they don’t fit the established meaning of VULOS.
