Researchers in the defence, peacekeeping, safety and security division (DPSS) of the Council for Scientific and Industrial Research will integrate an electro-optical payload onto the science council’s modular unmanned air vehicle (UAV) in the near future.

The DPSS is undertaking a lot of research into electro optical systems. For example, into digital image enhancement, image stabilisation, and target identification and tracking.

Hitherto, the researchers have had to use towers as the platforms from which to conduct such research. By integrating it onto the UAV, they will be able to advance to the next stage of development by undertaking more realistic research.

The payload that is in the process of being integrated onto the UAV is being supplied by specialists South African development company Tower35.

The payload is a 1,2-kg system comprising a daytime zoom camera, with a three gimbals mounting, stablised in two axis (azimuth and elevation). The complete system is 125 mm in diameter.

This payload will be directly attached to the central port of the UAV. This electro optical camera payload is itself a self-contained modular unit.

It has a real-time data link to a ground station, which is equipped with an antenna that automatically follows the UAV. The camera can be controlled in real time from the ground. The camera system and the UAV can be controlled separately and simultaneously.

It is hoped to demonstrate this system on the UAV by the middle of next month.

This digital camera system has already been flown on manned aircraft, but this will be its first application for UAVs.
