The experiment SOYA conducted on board interplanetary station "Mars-96" is described. The experiment is intended for studying the internal solar structure by helioseismology methods. The experiment is based on the measurement of brightness oscillations on the Sun as a star. The amplitude of brightness fluctuations with respect to the average level is of order of 10~5. Detection of such small oscillations presents very high metrological requirements to the device. The design of the high-precision photometer SOYA is described.
