Oyster GPS

Ultra-rugged and long-life battery-powered GPS tracking device for asset tracking and management

The Oyster uses an accelerometer to detect movement, allowing it to decide when an asset is in-trip, and when it is stationary. This allows it to schedule the battery-hungry GPS fixes and transmissions as infrequently as possible, to maximise battery life. Each time a status update is scheduled, the Oyster will attempt a GPS fix, then transmit the results (whether or not the fix succeeded).
