The third satellite of Peter the Great St.Petersburg Polytechnic University has a number of payloads with various purposes. 

Antenna system with a built-in receiver of global navigation satellite systems (GNSS) signals is specially adapted for operation in low Earth orbits. One of the tasks is to correct errors and improve the accuracy of ground-based positioning systems.

Radio receiving equipment with specialized antenna-feeder systems for measuring the power of the spectrum in the band up to 50 MHz with an interval of 100 MHz in the frequency range of 0.1 ... 18 GHz will create a three-dimensional non-stationary model of the distribution of the level of electromagnetic radiation in various frequency ranges and build territorial maps of the distribution of these levels in the framework of long-term analysis. 

The satellite also includes an Automatic Identification System (AIS) module and an overview camera, which serves to evaluate the operation of the SC subsystems with resolutions of 640x480, 320x240, 160x120 pixels.

To correct the position in orbit, the spacecraft has a low-thrust gas engine.
