  Harry Wilder might be spending his gap year on the side of the world, but his mum is with him every step of the way.Thanks to a satellite tracking device, Rachel Wilder can keep an eye on her son at any time of the day or night.“It’s fantastic to be able to keep an eye on Harry and his journey,” said 53-year-old Mrs.Wilder, “I feel like I stay with him all the time on his travels, which means he doesn’t have to check in with a phone call.”

  Harry, who is in Australia with his friend now, agreed to carry the 2 in-thick, credit- card – sized Traakit device when he left home.By visiting a website, his mother can track him to within 15ft of his exact location and the global positioning system can even send her a text message alert if he goes anywhere he shouldn’t.“I can’t tell which street he is in but I can make sure he doesn’t wander into any dangerous area,” added Mrs.Wilder.Harry will travel to Thailand next month before heading to South Africa in July.He is due to start a degree in Business Management at Oxford University in September.

  The Traakit device was developed by Harry’s uncle David Clatton, 65.It costs £279 plus £11 a month.It triangulates(作三角测量)its position by taking co- ordinate(同等的)readings from four satellites.It feels the information back to a computer, which then maps out where it is in the world.

  Harry says he is happy to carry the tracker as protection against danger.“But if I didn’t want mum to know where I was going I can always leave the thing in the car.”
