The National Science Museum and the nation’s major mobile carrier will jointly develop a location tracking system to prevent dementia patients from getting lost.

The museum said on Monday that it will sign an agreement with SK Telecom and Korea Ecology and Environment Institute at the South Jeolla Provincial Police Agency on Tuesday to that effect.

The proposed system will be developed based on the location tracking system for wild animals such as migratory birds or mammals.

The current location tracking necklace requires recharging every eight hours and has a large margin of error of 100 meters, making it hard to pinpoint people with dementia when they are lost.

The museum plans to adopt a lithium battery for a new device so that it can last six months without charging. It will also reduce a margin of error for tracking to ten meters by using the commercial network of the mobile carrier.
