Comparison of drone specifications. The weight of the tag used in these estimates is 0.7 kg. The estimated flight time is based on the use of a 6S (22V averaged) 2900mAh battery and [12]. Note that the real world flight times are approximately 30% less than the theoretical values due to parameters such as video transmission (up to 9 W), drone design (motor arm and propeller guard impeding on the air flow), the flight environment (wind, air temperature, and density), and the drone operation (taking off or cruising towards the whale).
