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 L(subscript 4) and L(subscript 5). 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.
