MAIN CHARACTERISTICS OF THE SPACECRAFT:
Spacecraft weight, kg 1900
Scientific payload weight, kg 540
Orbit:
• type circular
• height, km 500
• inclination, deg 82.5
Accuracy of the spacecraft longitudinal axis orientation to the Sun, arc min better than 5
Determination accuracy of the spacecraft longitudinal axis orientation on the Sun, arc min 3
Angular velocity stabilization of the spacecraft, deg/s less than 0.005
Accuracy of the satellite position measurement:
• along the orbit, m ±1000
• by height and in transverse directions, m ±500
