Improvements being made to the control metrics are focused on their security. Tech experts are trying to ensure that the control systems are resistant to malware and can’t be hacked easily. In addition to this, new and improved control systems are being developed that provide on-ground pilots a greater degree of control over the drone’s movements.
As is the case with any other aircraft, communication systems are extremely important for drones. They are used by the ground staff to communicate with the drone and to provide necessary instructions to it.
