SUCHAN is an all-composite, lightweight, modular mini-UAV designed and developed by CSIR-NAL. It has been designed to meet high altitude operational requirements and has a ceiling altitude of 5000m above sea level. Being indigenously designed and developed, this mini-UAV is a far more cost effective solution than other UAVs with similar payload capabilities and gives the advantage in terms of support and services.

It can be programmed for autonomous missions or operated manually utilizing the advanced avionics and precise GPS navigation. Being hand-launched Suchan provides aerial observation, day or night (with interchangeable camera options), at line-of-sight ranges up to 10 kilometres. It comes with a retractable 2-axis stabilized gimbal, which delivers real-time colour or infrared imagery to the indigenously designed and optimized ground control stations.
