The method of calibrating diode temperature sensors, based on a combination of two generalized methods: spline interpolation and approximation using orthogonal Chebyshev polynomials. The program of implementation of the OS Android. The established requirements for calibration carried out to obtain the final result thermometric curve as accurately as possible. It automates the process of obtaining the interpolation table and optimize calibration procedure. The method for approximating the characteristics tested termodiod sensor type DT-471 company Lake Shore.

Purpose. Solutions to the problems of coordinate-time provision based on continuous GNSS-observations is based on the processing of large data sets of code and phase measurements. One of the possible additional options for conducting this study is computation of the numerical characteristics of the ionospheric impact on the signals distribution from the satellites – the values of the total electron density (TEC). These characteristics reflect the dynamics of the atmosphere ionization that is important in terms of monitoring the circumterrestrial space.
