(Continuation from yesterday)

If this was an "outdoor" scene, it was still possible.

Using Michibiki, RTK devices (which have become cheaper recently), and the position hopping problem were corrected by Kalman filters.

However, about "indoor", this level of positioning accuracy cannot be guaranteed.

At least, about 100 devices for observing weak positioning radio waves are installed in the facility, and a large amount of correction processing calculations must be continued in real time on a high-performance computer.

In addition, it must be processed by the number of children.

It is necessary to operate a positioning system, which is more expensive than the cost of ten of "child care facilities" managements.

Including the system construction cost, it is impossible for me to estimate.

With this indoor precision positioning, many people (me too) have been struggling for decades, and I have not yet completed a satisfactory system.

In the world of "Promised Neverland", I thought that it would be realized how this was realized.

If they have such advanced positioning technology, the level of reproductive technology will be reasonably higher --- So,

I thought something brutally frank, like "why don't they try to mass-produce cloned humans with high intelligence, and turn them into food ?"
