This article was first presented to the world a new kinematic effect: "The accuracy of orientation platform inertial navigation system and strapdown inertial navigation system based on the same gyros differs even when identically matching errors and noise as part of gyroscopes platform inertial navigation system and strapdown inertial Navigation System. " One manifestation of this effect: "Noises gyro with zero values ​​of noise power spectral density at zero frequency do not lead to a significant increase in errors orientation platform inertial navigation system (second-order effect" small "), but lead to a very substantial increase in strapdown inertial orientation errors navigation system (first-order effect "small"), "The difference between the partial contributions of noise in precision targeting platform and strapdown inertial navigation systems is of the order (10, 100, 1000 and more times), depending on the structure and type of noise gyroscopes rotating object .

The article presents a technique that contributes to improving the accuracy of the ball in volleyball. Volleyball is a basic sport in the program of schoolchildren, but most often students are not taught tactical moments of the game. The outcome of the game as a whole depends on the pitch and accuracy plays a big role in this. In the learning process, it is important to devote time to its development, because this way students will be able to show their personal qualities and realize themselves in the game without the participation of other players. After analyzing the scientific literature, the author of the article proposed a special set of exercises that improves the accuracy of the presentation of schoolchildren. The effectiveness of the proposed complex has been proven on the basis of tests that reveal the level of accuracy of the ball.
