Background

The Missions of Project Ionozond includes four Ionosfera-M and one Zond Satellite. The function of Ionosfera-M satellites is to monitor the Magnetosphere and Ionosphere, while the function of Zond is to measure Solar Irradiadion.^[2]

Zond part of the program was initially planned to fly with the Ionosfera-M Satellites in 2020 to observe Sun. But due to lack of funding is in hold position and possibly cancelled.^[3]

Each Ionosfera-M Satellites carries the following instrument:

• SPER/1-Plasma and energy radiation spectrometer
• SG/1-Gamma-ray spectrometer
• GALS/1-Galactic cosmic ray spectrometer / 1
• LAERTES-On-board Ionosonde
• NBK/2-Low-frequency wave complex
• ESEP-Ionospheric plasma energy spectrometer
• Ozonometer-TM Ozonometer
• MayaK-On-board radio transmitters
• PES GPS-GLONASS device
