What is the term for the maximum distance error between actual radar location and true radar location?

• A. Location Uncertainty
• B. Azimuth Uncertainty
• C. GIP Uncertainty
• D. Compass Error

Answer: (A)

Location uncertainty is the term for the maximum distance error between where the radar is reported to be and where it actually sits. This measures how far off the radar’s stated position can be from its true position, considering all sources that can shift its reported coordinates such as sensor biases, timing delays, and datum differences.

Azimuth uncertainty, by contrast, relates to errors in the angle to a target, not the radar’s own location. Compass error concerns the radar’s orientation or heading, which affects direction readings but not the positional offset itself. GIP Uncertainty isn’t the standard term used for location error.
