SamSat-Ionosfera

SamSat-Ionosfera is a 3U CubeSat nanosatellite, developed, manufactured, and tested by the Interuniversity Department of Space Research at Samara University. It is an enhanced version of the SamSat-ION nanosatellite, which was launched into orbit on June 27, 2023. The launch of SamSat-Ionosfera is scheduled for November 5, 2024, from the Vostochny Cosmodrome.

SamSat-Ionosfera is designed to solve several scientific and technological tasks. The scientific objectives of the nanosatellite include:

  • Investigating the parameters of the upper ionosphere, plasma states, and the Earth's magnetic field along the satellite’s trajectory;
  • Studying the features of the nanosatellite's motion dynamics under three-axis gravitational orientation, achieved through the selection of design parameters (passive stabilization) and the use of magnetic actuators (active stabilization).

The technological objectives of the nanosatellite include:

  • Testing the technology for high-precision spatial-temporal referencing of scientific measurements;
  • Verifying algorithms for preliminary processing and compression of scientific data onboard the nanosatellite;
  • Verifying algorithms for preliminary processing and compression of scientific data onboard the nanosatellite;
  • Testing the technology for opening transformable nanosatellite structures;
  • In-flight testing of the second version of the SamSat platform’s service systems;
  • In-flight testing of the plasma parameter sensor;
  • In-flight testing of the navigation receiver.

For radio amateurs::

The SamSat-Ionosfera (callsign RS75S) beacon signal is automatically transmitted at regular intervals on a frequency of 437.3986 MHz in FSK AX.25 1200 bd mode (USB modulation).
