noun - SPOT (or the SPOT Satellite GPS Messenger) is a GPS tracking device that uses the Globalstar satellite network to provide text messaging and GPS tracking depending on the subscription type purchased. The SPOT Tracker has a coverage area that includes a large portion of the planet, with the following exceptions: extreme northern and southern latitudes, south-eastern Africa, India, and adjacent areas immediately north of India.
With the purchase of a basic annual subscription, users including channel swimmers and marathon swimmers can push information on their location to emergency services. For an additional cost, SPOT can transmit a breadcrumb trail of GPS points, which users can configure to be displayed on a custom web page. These points are transmitted every 10 minutes, but include only latitude and longitude data, no elevation/altitude is possible. This allows marathon swimmers and channel swimmers to inform their family, friends, and the media of their location during an open water swim by placing a SPOT Satellite GPS Messenger on their escort boat.
In 2010, SPOT claimed to have successfully helped initiate more than 550 rescues in 51 countries on land and at sea.
