On April 13, the St. Petersburg State University of Aerospace Instrumentation hosted a traditional exhibition of scientific and technical creativity.
The event is timed to coincide with the opening of the 79th Annual International Student Scientific Conference. This year, the exhibition brought together about 60 unique exhibits reflecting the university’s key competencies. The participants presented innovative developments in such strategically important areas as the aerospace industry, instrumentation, metrology, radio engineering and programming.
A special place in the exhibition was occupied by developments on space subjects. Students of the SUAI Institute of Aerospace Instruments and Systems presented a mobile platform for a ground-based complex that provides experimental testing and research of control, orientation, stabilization and navigation algorithms for small spacecraft in an orbital constellation. The platform receives control signals directly from the test apparatus: the rotary-tilt table receives a signal for the unit of flywheel motors of the apparatus, and the wheelbase for the engines of the apparatus. After the signal conversion, the platform performs equivalent movements and rotations, thus simulating the movement of the spacecraft in orbit under ground conditions.
Another notable student project was an extendable system for a small CubeSat 3U spacecraft due to the movement of gear rails. The mechanism allows you to change the geometry of the device to control its rotation by shifting the center of mass; it is used for deploying flexible solar panels and antennas, as well as for docking with other objects. One more significant project was dedicated to an automatic rescue system for a training rocket in the CanSat competition. Unlike classical pyrosystems, this installation is activated by an altitude sensor, ensuring a smooth two-stage landing of the carrier and payload on parachutes. This solution guarantees high landing accuracy and equipment safety, which is critically important during launches and tests of microsatellites.
A large block of projects was devoted to unmanned aircraft systems, and two IT projects of the Institute of Information Technology and Programming also stood out in the exposition. The first is a hardware and software complex for automated monitoring of electrocardiographic data. The second development is an application for automating process management with constraints in the field of transport logistics.
