Each of the ACCESS devices fits in the palm of your hand, with typical dimensions between 2 and 6 inches (5-15 cm) and weights between 0.4 and 7.3 lb (0.2-3.3 kg). The small size and weight make the devices easy to deploy on a UAV, small research aircraft, balloon platform, or even inside a backpack.
