Watch Window Types

There are a number of different types of watch windows that can be displayed in SA. They include:

 

Watch Instrument’s Point Position.

This watch window displays the coordinates of the center of the instrument’s probe. It will update whenever updated data is received from the instrument.

 

Watch Closest Point

A closest point watch window will automatically compare an instrument’s probe position to the closest of a set of points. This set of points can be an entire group or a selection of points from a single group, or multiple groups. This watch window will automatically switch be- tween points, displaying the name of the point to which it is comparing. Offsets are not used in point to point comparisons.

Watch Point with View Zooming

This watch window functions the same as a point to point window, but automatically zooms the graphical view and plays a sound whose pitch is proportional to the proximity of the target to the point. Off- sets are not used in this comparison.

 

Three Point Frame and Two Point Axis Alignment

Watching a three point frame is a fairly unique operation. It involves watching three 3-DOF devices simultaneously. Two measured points are used to calculate pitch and roll from a given coordinate frame. More details here: Watch Three Point Frame

 

Compare Point to Point Position

Much like Watch Closest Point this displays the deviations from the instrument position to a single selected reference point.

 

Compare Point to Objects Position

Compares the instrument’s compensated probe position to the closest of one or more objects. More details here: Point to Object Watch.

 

Relationships.

A number of relationships can have a watch windows added in order to view that relationship’s deviations.

Points to Objects Relationships return live status reading:

Frame to Frame Relationships return a live reading of the relative position of two frames:

 

Theodolite Observer Point to Point.

Compares a point derived from two or more theodolite observations to any other point. More details here:Theodolite Data Observer
