Which feature, when set to zero, might allow a GPS unit to have an accuracy equivalent to Precise Positioning Service receiver capability?

🔍 Key Concepts

• GPS accuracy levels: Standard Positioning Service (SPS) vs Precise Positioning Service (PPS) • How intentional signal degradation was used on older GPS for non‑military users • Which GPS feature, when turned off or to zero, removes that deliberate degradation

💭 Think About

• Think about which option refers to an intentional error that used to be added to civilian GPS signals to reduce their accuracy. • Ask yourself: if you could set that intentional error to zero, what would happen to the receiver’s accuracy? • Eliminate any answers that are simply types of systems, signal protections, or processing methods rather than an added error term.

✅ Before You Answer

• Identify which choice is associated with intentional degradation of civilian GPS accuracy in older systems. • Confirm which item, if set to zero, would effectively remove the added error and let civilian receivers approach PPS-level accuracy. • Make sure the feature you pick is not just a type of satellite system or a security feature like anti-spoofing.
