MicroTrack is a micro GPS (Global Posisioning System) tracker with customisable weights, the smallest being 3.5 grams! The weight is dependent on the battery size, so there is a trade-off between weight and battery life. The MicroTrack weighs only 3.5 grams with a 100 mAh battery, 4.5 grams with a 200 mAh battery and 7 grams with a 400 mAh battery.

MicroTrack needs to be recovered in order to obtain the position data. The size and weight of the Microtrack means it can be used for a wide range of applications, from small animals like birds to personal assets like cars.
