New Tech May Help Find Missing People In the Backcountry Within Minutes
A new tool called Lifeseeker could help search and rescue teams find missing people in minutes using their cellphones. The technology acts as a miniature cellphone tower, allowing rescuers to pinpoint cellphone locations within a 3-mile radius, significantly improving the efficiency and success rate of search missions in challenging terrains. The Colorado Sun reports: "As we detect the phone, basically a blotch shows up on the map and as we fly around that area, that blotch gets smaller and smaller and smaller until we can see exactly where they are," said Dr. Tim Durkin, a search and rescue program coordinator for Colorado Highland Helicopters. "That process of detecting, focusing on one specific location takes about a minute -- not really very long at all." Depending on the situation, search and rescue teams can then send in ground crews with the person's location or land the helicopter if there's a clearing nearby and conditions allow for a safe landing, Durkin said. During a test mission in La Plata Canyon northwest of Durango, search crews found the two people they were looking for within two minutes and 14 seconds, Durkin said. The technology, called Lifeseeker, was developed by Spain-based company CENTUM research & technology and is in the process of being approved by the Federal Communications Commission before it can be sold to the state or counties hoping to use it for their SAR efforts, he said. [...] The radio-based technology needs a clear view of the terrain without interference to pick up the signal of the cellphone. If the conditions and terrain are favorable, it can detect a cellphone up to nearly 20 miles away. It takes about three minutes to attach the Lifeseeker unit inside a helicopter when needed for a search and rescue mission, Durkin said. SAR can also use the tool to send text messages to the missing person, for example, advising them to stay in one area if they are hurt or move to a clearing for a helicopter to pick them up. The tool also has a broadcast function that allows SAR to send out a message to a group of people within a certain range, similar to an Amber Alert for a missing child, to warn them of a wildfire or flood, Durkin said.
