With regard to GPS, a civilian receiver may be capable of achieving the same accuracy as a military receiver if __________.

🔍 Key Concepts

• Selective Availability (SA) and its effect on civilian GPS accuracy • Difference between geometry/dilution of precision (DOP) problems vs. intentional signal degradation • What features are unique to military GPS vs. civilian GPS receivers

💭 Think About

• Ask yourself: Under what condition would the intentional accuracy difference between civilian and military GPS disappear? • Which answer choices would make GPS accuracy worse rather than better? Think about satellite elevation and high vs. low DOP. • Consider whether adding extra equipment on your vessel changes the GPS signal itself, or just how you process it.

✅ Before You Answer

• Identify which option refers to intentional signal degradation by the GPS system operator, not just geometry or extra sensors. • Check which choices clearly decrease position accuracy (e.g., poor satellite geometry, low elevation satellites). • Confirm which single condition would allow a civilian receiver to use essentially the same ranging information quality as a military receiver.
