Development of rifle electronic simulators (i. e. for hand weapons and not using ammunition) is an important task since the production of any type of small arms, according to regulatory documents, requires also production of a simulator to instill aiming and firing skills. The developing family of electronic shooting simulators "STrIzh" includes three publicly available levels for self assembly: initial, basic and virtual. Structural diagrams of aiming point’s recorders of initial and basic levels are presented and studies of their mathematical models with estimation of errors are carried out. Ability to self assemble a shooting simulator from publicly available components (laptop, webcam, weapon layouts, IR LEDs, projector, lasers, HD-camera) contributes to their widespread use. Such use is based on the program exercise support under development and methods of assembling and adjusting the targeting point recorders and weapon simulators. Studies of recorders for the error in determining of the aiming point showed acceptable accuracy and manufacturability of mathematical models’ calibration with the ability to take this error into account in the simulated ballistic dispersion of ammunition. Possibility of registration speed increasing and possible approaches for increasing of the accuracy and fixation of the pile and the distance to the workplace with the possibility of recalculating the angular dimensions of the target situation to the real one were investigated also. The simulator family’s software algorithm should fully support the initial and basic levels of implementation with various training equipment configurations and include a multimedia shooting training system. For the virtual level of the simulator (a virtual reality helmet on a smartphone and a weapon’s layout with a smartphone), one needs to develop his own software (it will be discussed in the next articles).
