🔍 Key Concepts

• Differential GPS (DGPS) improves basic GPS accuracy by using shore-based reference stations • The U.S. Coast Guard Maritime DGPS system is designed for high-precision navigation near the coast and in harbors • Think about typical GPS accuracy (without DGPS) versus enhanced accuracy with corrections

💭 Think About

• First, recall the approximate accuracy of standard GPS available to the public. Is it usually closer to 10 meters, 50 meters, or 100 meters? • Next, ask yourself: when we apply differential corrections, does the error get larger or smaller than standard GPS? By how much? • Look at the answer choices and consider: which of these distances would make sense for safe harbor and coastal navigation where precise positioning is important?

✅ Before You Answer

• Verify that DGPS is more accurate than uncorrected GPS, not less accurate • Confirm that maritime DGPS is designed for meter-level accuracy, not tens of meters • Before choosing, compare each option to what you know about typical consumer GPS accuracy to see which seems the most "improved" value
