Several indigenously developed payloads are now available for UAV applications, such as electro-optic imaging, laser ranging and designation system, airborne laser ranger and marker (ALARM), and airborne infra-red target sensor. The gimballed payload assembly (GPA), a two-axes stabilised platform for CCD camera and laser range finder payloads, has been developed to provide azimuth and elevation stabilisation of the sight line against aircraft motion and jitter. An advanced correlation technique-based video tracker has been integrated with this platform for automatic target tracking. The entire system can be installed on manned or unmanned aircraft. The system can also be configured to carry different electro-optic payload combinations.
Two types of scoring systems have been developed as a part of Lakshya aerial target tow body electronics for estimation of the miss distance. The acoustic miss distance indicator (AMDI), which utilises the over pressure produced by the supersonic projectile to estimate the miss distance, provides both distance and sector information. The other system is based on Doppler FM-CW radar principle.
Comprehensive capabilities have been established in all aspects of flight control design and engineering for unmanned air vehicles (UAVs) which include design of control laws, flight control electronics, sensors and actuators. Digital processors, software and analog flight control electronics and electromechanical actuators have been developed. The flight control electronics (FCE) for Lakshya aircraft employs an analog electronic design backed by an ASIC to perform flight control and recovery functions of the aircraft. In addition to altitude stabilisation and other flight control functions, the FCE also provides command and autopilot modes.
