Abstract
The method of leak integrity evaluation of the spacecraft in orbit using data from vacuum pressure transducers located on the outer surface of the spacecraft was suggested. Distribution of gas concentration flowing from a point source was considered. Localization of leak and determination of its size is performed by analyzing the distribution of gas concentration in the outer atmosphere of the spacecraft. Designs of the transducers and their characteristics are given.

Key words
Vacuum, vacuum gauge, leak integrity, spacecraft.
