How the System Works
When your pet approaches the established boundary, the GPS Mobile Unit generates a tone and
correction to remind your pet of the boundary. With training and praise, your pet will quickly learn to
avoid the established boundary.
Definition: A Correction is a training term used to describe an action taken to discourage unwanted pet
behavior. The GPS Mobile Unit applies a correction when your pet crosses the boundary of an Invisible Fence
®
Brand electronic pet containment system. Corrections are used in combination with rewards to alter unwanted
pet behavior.
A “Fence” is defined by posts and the line segments that connect consecutive posts. The pet will be
contained within the area enclosed by the “Fence”. Each post consists of a pair that defines its location
on the Earth (latitude, longitude). Posts are obtained from Google Maps
™
mapping service and are
entered and stored in the GPS Mobile Unit. The GPS Mobile Unit determines the pet’s position, speed,
and course from an internal GPS receiver. These observations determine if the pet is violating one of
the boundary tests and requires a warning correction. The Mobile Unit will take corrective action when
any of the following occur:
 Anti-Linger Violation – The pet is lingering too close to the containment boundary.
 Time To Boundary Violation – The pet is approaching the containment boundary at a speed
and course such that the anticipated time to the boundary is 3 seconds or less.
 Out Violation – The pet is more than 4 feet outside the containment area
