Calibration

The calibration tools enable you to resolve navigation latency and transducer mounting offsets and update the HVF from within Subset Editor.

Most errors are detected by examining along track patterns. An exception is roll errors for which across track patterns are compared

The calibration process consists of comparing pairs of lines within a defined subset, rotating the subset parallel or perpendicular to the lines depending on sensor values being examined. The process is repeated for all sensors. (See Defining subset area for calibration for information on positioning the subset.)

An additional comparison can be done by creating a surface from the un-calibrated data, calibrating the data, and then creating a new surface to see and compare the effect of the calibration values.
