• A. Rover
• B. Satellite
• C. Data link
• D. Base station

Answer: (A)

Real-time kinematic relies on a radio frequency link between a base station with a precisely known position and a moving rover. The base computes differential corrections from its GNSS observations and broadcasts them to the rover in real time. The rover uses those corrections to refine its own GNSS measurements, resolving carrier-phase ambiguities and delivering a centimeter-level position as it moves. The corrections travel over a dedicated radio link (often UHF or VHF), not through the satellites themselves. While a data link could exist in some setups, the essential RTK requirement is the real-time radio connection from base to rover.
