Abstract: The invention relates to remote control of aircrafts and is intended in particular for guiding controlled rockets to target by laser ray. A sighting device for guiding portable set comprises sighting channel installed in the body, this includes connected in sequence a television camera with objective and first photodetector installed in its focal plane, a unit for formation of aiming mark first input of which is connected to output of the first photodetector and which has output for connection to monitor, a laser guiding channel optical axis of which is parallel to optical axis of sighting channel, this includes installed in sequence a laser illuminator, an optical modulator with first drive, a pancratic lens that includes second drive and first position sensor, as well as an electronic control device and system for channels check, this includes first reflection prism placed at outlet of the sighting channel and laser guiding channel in such way that its input facet is optically connected to pancratic lens and output facet – to objective of television camera and installed with possibility to take it from ray propagation line for those going out from laser guiding channel and falling to sighting channel. The sighting device has as well excess device placed on the optical axis of laser guiding channel after pancratic lens, this includes optical deflection module, third drive and second position sensor, and laser range-finder that includes transmission channel that includes pulse laser and transmission optical system, and receiving channel that includes receiving optical system and second photodetector, at that optical axes of receiving and transmission channels are parallel to optical axis of the sighting channel. The laser illuminator is arranged as continuous operation laser with radiation wavelength in infrared range. The optical modulator is arranged as raster with code lines to perform space-time modulation of radiation of continuous laser and installed with possibility of rotation by means of first drive and equipped with tacho-generator. The electronic control device includes controller that includes first micro-processor and module for control of laser guiding channel, this includes second micro-processor, at that the controller has at least first input for entry of control commands from external control device, second input for connection of external programming device and control apparatuses, third input connected to output of second photodetector, fourth input connected to the first output of control module for laser guiding channel, first output connected to second input of block for formation of aiming mark, second output connected to input of pulse laser, third output connected to input of laser illuminator, fourth and fifth outputs connected to the first and the second inputs of module for control of laser guiding channel, third, fourth and fifth outputs of that one are connected to tacho-generator, first and second position sensors, and second, third and fourth its inputs – to the inputs of first, second and third drives. The invention provides secrecy and increases noise protection of guiding device of portable complex, increases probability of target hitting under conditions of locality roughness close to sight line due to inclusion of modes of program-controlled exceeding of control field over sightline with increase in such way of accuracy of guiding controlled rocket to target with provision of simplification of design of laser illuminator and optical module.
