🔍 Key Concepts

• Global coverage and control of GPS by the U.S. government • Typical number of satellites in the GPS constellation vs. the minimum needed • How many position lines / satellites are needed for a 2D fix vs. 3D fix

💭 Think About

• Think about who owns and operates GPS and whether they can turn parts of it off or degrade it for security reasons. • Consider whether GPS is designed for worldwide use or only certain regions—what does "global" in Global Positioning System imply? • Recall the difference between the total number of satellites in orbit and the minimum number required for a fix (and what kind of fix: 2D vs 3D).

✅ Before You Answer

• Check which choice correctly reflects that the U.S. can control GPS availability or accuracy. • Verify whether 12 satellites sounds like the total constellation or just a minimum number in view for a user at any one time. • Confirm from your nav theory how many lines of position (or satellites) are needed for a 2D fix versus a 3D fix, and see which option matches that.
