Q

Most GPS receivers use the Doppler shift of the carrier phase to compute __________.

🔍 Key Concepts

• Doppler shift and what it measures in navigation systems • How GPS determines a vessel’s position versus its motion • Difference between parameters derived from timing signals and those derived from frequency/phase changes

💭 Think About

• Ask yourself: Does a Doppler shift directly tell me where I am, or how I am moving? • Which of the four choices would most logically come from measuring a change in frequency over time rather than an absolute time signal? • Think about which GPS output can be obtained very quickly and accurately from small changes in the received signal’s carrier wave.

✅ Before You Answer

• Be clear on the difference between position (latitude/longitude) and motion (how fast or in what direction you’re moving). • Remember that GPS timing is based on precise clock signals, not mainly on Doppler shift. • Check which option is most directly related to a rate of change that could be inferred from the Doppler effect.
