TracBack is a new ultra-mini GPS sensor from Marine Electronic Services, which measures just 70 x 45 x 20 mm. It incorporates a long-life lithium ion battery pack so that the system can be self-powered. GPS data is sent through either a standard USB connection directly to a laptop or via Bluetooth for a wireless-type link.
The internal battery lasts for approximately 15 hours and can be recharged using either the supplied mains charger or USB connection. The mind boggles at potential applications, such as tracking vehicles, yacht racing or even sharing your track history with other friends and colleagues.
