🔍 Key Concepts

• GPS positional accuracy under normal conditions without Selective Availability (SA) • Typical civilian GPS horizontal accuracy in meters (95% of the time) • Difference between theoretical best-case accuracy and what is typically quoted for practical use

💭 Think About

• Which choice is closest to the commonly quoted horizontal accuracy for standard, non-augmented civilian GPS receivers when SA is OFF? • Are exam questions usually based on "perfect lab conditions" or on a conservative, real-world, published figure? • Compare each option to what you’ve heard as the typical GPS accuracy value in meters for marine navigation.

✅ Before You Answer

• Verify the commonly published horizontal accuracy for civilian GPS without SA or augmentation (like WAAS/EGNOS). • Check whether any option looks like a best-case, ideal lab number that might be too optimistic for exam purposes. • Eliminate values that are clearly too coarse for modern GPS (e.g., would make close-in harbor navigation impractical).
