Abstract
This paper presents the results derived by exploring the possibilities of creating an interplanetary stereoscopic observatory to investigate the 3D structure solar features from granules and spicules to coronal structure. A preliminary stage was made of the passive motion of two spacecrafts in the vicinity of Lagrangian libration points L4 and L5. The version of ballistic scheme of setting-up of the system with a minimal deployment time is considered. For preliminary development of stereoscopic SC the main parameters of scientific payload have been taken: mass - 600 kg, power's - 1 kw, summary data - 5 Gbits per day. The chief results of this work are: (1) the stereoscopic observatories can be realized with a complete set of achievable objectives, (2) launching of SC with the mass 2000 kg into both libration points is possible by using Soviet rocket-vehicle `Proton' in a time 1.17 year, (3) transmission of information from stereoscopic observatory amount 5 Gbit per day is possible by the ground-based antenna 70 m in diameter and using, aboard the SC's, a transmitting-receiving phase-array antenna of size 5 X 5 m.
