The telescope is planned to be launched by a Zenit-2SB medium-class launcher equipped with a Fregat accelerating module. All launch facilities will be provided by Russia. The observatory is expected to operate for about 10 years.A geosynchronous orbit with an inclination of 51.6 degrees has been chosen. For this orbit the effects of the radiation belts will be negligible and the observing efficiency high. The figure above illustrates the trace of the geosynchronous orbit.
