Using the new WLT, drift error was found to be 0.37%, versus 1.14% without, more than a 3x
improvement. Over a distance of 50m this is a difference of nearly 0.4m (1'3") in error.
It is clear that by integrating World Locking Tools within the TCH platform, Trimble is able to
offer a significantly improved model viewing experience to our users. With drift and scale error
known, it is now possible to define best practices for an optimal user experience. To mitigate the
effects of these errors, we suggest that users keep the radius of their mixed-reality work area
limited to less than 50m (160'). When working beyond these limits, it is suggested that the user
realign their model every 50m (160') in order to best mitigate the impacts of drift. This
recommendation may shift depending on a user's individual precision and accuracy needs.
