Development and Testing of an Electronic Barometer for Stratospheric Cosmic Ray Radiosondes

As part of the program for upgrading a stratospheric radiosonde for cosmic rays, an electronic barorelay was developed using modern circuitry elements. This article considers its design and characteristics. The results of test flights with the electronic barorelay and flights with a mechanical barorelay during similar solar activity in 1978 are also compared. According to the results of all tests, it is recommended to use an electronic barorelay in the radiosonde circuit.
