The Oyster2 is fitted with a 3-axis accelerometer which allows the device to ‘sleep’ in an ultra-low power state yet still wakeup when movement occurs. The GPS and accelerometer are used in tandem to intelligently determine when the device is moving, and increase the frequency of location updates. When movement ends, the update rate is scaled back to once per day. This ensures that up to date location information is always provided, without wasting any data or battery life.
The frequency of updates is easily configurable Over-the-Air, so that the desired update rate or battery life can be achieved.
