A Massey University alumnus, James McCarthy has invented an aircraft locator system that tracks flights in real-time. Called Spider, the portable device that plugs into a lighter socket, relays the aircraft’s GPS position to the internet through an Iridium satellite network modem.
In the event of crash, the impact can cause standard locator devices to fail, minimizing the chances of rescue. Powering on at take-off, the Spider sends its location every two minutes - a more effective system for not just aircraft, but usable in vehicles and boats too.
