Sun Glint

Data acquired over water will be corrupted by sun-glint contamination. The amount of sun glint is evaluated with the "sun glint normalized reflectance" and calculated according to a specific algorithm. The sun glint normalized reflectance

The constraint can be applied to a sensor or to an AOI, and allows to set minimum and maximum values of sun glint for each swath.

A sensor or an AOI can be set with the sun glint constraint. You can set min or max glint values. SaVoir will steer the sensor considering this constraint.

See the example below: Several wedge shaped AOIs are defined on the field of regard zone. The shapes are such that the largest coverage is obtained at the West of the wedge. Therefore the steering preferred is such that all swaths are at the extreme west of the field of regard . If you set the glint constraint ON with max = 0.005, the steering will change to dodge the high glint zones.
