Modern missions dedicated to solar and heliospheric physics requires out-of-ecliptic orbits of a spacecraft (SC). The effective implementation of missions such as ESA Solar Orbiter or the Russian Interheliozond project is impossible without using gravity assist maneuvers (GAMs). Knowledge of SC delivery error estimations is crucial for the missions using GAMs. Such estimations are required not only at the mission development stage, but also at the mission execution stage. Errors estimations of the SC delivery to planets for GAMs were made for the mission Interheliozond, intended to study the Sun from close distance. Some results of calculations are presented.
