Interkosmos 22 (Bulgaria 1300)
The spacecraft contained a set of plasma, particles, fields, and optical experiments that were designed and constructed in Bulgaria. The spacecraft was three-axis stabilized, based on the Meteor bus, with the negative Z-axis pointing toward the center of the earth and the X-axis pointing along the velocity vector. The outer skin of the spacecraft, including the solar panels, was coated with a conducting material in order to allow the proper measurement of electric fields and low energy plasma. Both active and passive thermal control were employed. The solar panels supplied 2 kW and batteries were used during eclipse periods. There were two tape recorders, each with a capacity of 60 megabits. The transmitter radiated about 10 W in the 130-MHz band.
