Site calibration is a process divided into 2 unique categories. What is one of those categories?

• A. Azimuth calibration
• B. Pitch and Roll (roll and crossroll)
• C. Elevation calibration
• D. Time calibration

Answer: (A)

Site calibration measures how accurately the system translates angles into real-world directions, and it’s done in two directions: horizontal and vertical. One category is azimuth calibration, which lines up the horizontal angle with true bearings. This fixes any misalignment of the rotation axis, encoders, or mounting so that a given azimuth corresponds to the actual bearing on the ground. The vertical counterpart is elevation calibration, which ensures the vertical angle is correct. Other options refer to timing or platform attitude in ways that aren’t the two standard site calibration categories, so azimuth calibration is the best choice because it directly addresses aligning the system’s horizontal angle with true geography.
