Length

Define threshold, minimum and maximum Length constraints for each swath.

• Threshold:  If an acquisition is shorter than the defined threshold, it will be cancelled
• Maximum:  If an acquisition is longer than the defined maximum, it will be shortened to comply with the constraint.
• Minimum: If an acquisition is shorter, then it will be extended to comply with the constraint.

  Constraint OFF	Length Constraint: Min = 100 km, Max = 600 km

• Rest: Optional minimum interruption interval in the acquisition sequence. For example, some satellites can acquire a maximum strip length, and then interrupt acquisition for a given Rest time, needed for emptying their on-board flash memory into the recorder, prior to restart acquiring.

  Constraint OFF	Max Length= 140 km	Max Length= 140 km, Rest = 30 sec

• Trim Side: Defines the side for applying the constraint, whether end of swath, start of swath or center (both sides). It is also possible to select two additional options
  • REMOVE: will delete the conflicting item from the collection with attempting to resize it
  • MAX COVER: will select new start and end times maximizing area coverage.

Trim Side = START	Trim Side = CENTER	Trim Side = END
