The article presents two methods of modeling discrete heights of a quasigeoid on a local area of the earth’s surface using a gen-eralized Fourier series. The first method is based on modeling the characteristics of the earth’s gravitational field on a plane and involves the use of a two-dimensional Fourier transform by an orthonormal system of trigonometric functions. The second method consists in the expansion of the quasigeoid heights in a Fourier series by an orthonormal system of spherical functions on a local area of the earth’s surface. The errors of approxima-tion of the obtained discrete values of the quasigeoid heights on the local territory are analyzed. It is shown that with the modern computing technology, the most accurate and technologically simple way to model the quasigeoid heights on local areas is to expand them into a Fourier series by an orthonormal system of spherical functions.

The formulas are obtained for estimating the «random walk» type noise of algorithmic compensation for the gyro bias. An example of estimating the statistical significance of the factors influencing the bias when calibrating a fiber-optic gyroscope in the operating temperature range and at different rates of their change is given. It is shown that the random error of temperature sensors can play a major role in the “random walk” noise of the algorithmic compensation for the gyro bias and exceed the gyro self noise. An example of obtaining a regression dependence of algorithmic compensation for gyro bias using a neural network with a multilayer perceptron is given. The factors influencing the choice of the time constant of the differentiating low-frequency temperature filter are considered. Experimental dependences of the random error of the bias algorithmic compensation on the value of the random error of temperature sensors are presented and the necessity of using temperature sensors with a minimum random error is shown.

The paper presents a brief history of preparation for and execution of the first manned flight into space in the Vostok spacecraft. The main tasks and challenges which were solved to make this historical event possible are discussed. Further achievements of Russian manned cosmonautics are presented, including the first world’s orbital station Salyut which was constructed and launched in orbit 50 years ago. The human role in executing a space flight is studied. The tasks in the space orbit are discussed, the solutions to which with the participation of the crew have improved the space flight safety and efficiency. Examples of cosmonauts’ operations during the flights of the orbital stations Salyut, the orbital facility Mir, and the International Space Station are given to illustrate such tasks. The importance of cosmonauts’ participation in the research and experiments on the orbital stations is demonstrated, and positive examples of such participation are provided.
