Your vehicle is located every 30 seconds*, 1, 2, or 5 minutes while it is in motion (depending on the service you purchase). Sometimes your vehicle will be out of cellular coverage but you will still receive these locations when your vehicle comes back into cellular coverage. However, there will be times when your device is hidden from GPS satellites so you will miss these locations but that should be infrequent.
