With the ILR-33 BURSZTYN 2K rocket, a cost-effective, scalable and environmentally friendly design, we have the ability to efficiently experiment in microgravity and probe the atmosphere. The ILR-33 BURSZTYN 2K rocket is used during flight as a suborbital test platform, capable of providing up to 150 seconds of microgravity conditions for a 10 kg payload. The payload compartment can be adapted to the Customer’s requirements, providing the best possible test conditions.


The ILR-33 BURSZTYN 2K rocket is a flying suborbital platform designed at Łukasiewicz – Institute of Aviation. ILR-33 BURSZTYN 2K is offered as a standalone product, as well as a platform that enables research services. Powered by a hybrid rocket engine, supported by two auxiliary engines, it allows the mission to be tailored to the specific needs of the cargo being lifted.

Avionic rocket control systems

We are working on avionic equipment for rockets in three areas:

  • Measurements

We have extensive experience in integrating systems for measuring, among other things, basic flight parameters such as linear and angular velocities and the spatial position of the rocket. We have used proprietary inertial navigation algorithms, which enable short-term autonomous navigation calculations, in the on-board computers of the rockets we have developed.

  • Control

We have developed flight control algorithms for rockets made at the Institute of Aviation.
In the ILR-33 AMBER 2K rocket, the on-board computer controls the rocket flight by means of coordinated inclination of the control surfaces – four canards placed symmetrically in the front part of the rocket. In other rockets – by means of control motors located around the rocket’s hull.

  • Special features

We have also developed algorithms responsible for the implementation of the assumed flight plan and the electrical initiation of other rocket systems, such as the launch system, separation system or landing part recovery system. The rocket’s on-board computer, designed and built, is an example of this type of solution.

The developed algorithms and control methods are implemented by on-board computers designed, manufactured and tested in one of our certified laboratories.

  • On-board computer for the ILR-33 BURSZTYN 2K rocket

As part of the ILR-33 BURSZTYN 2K program projects, our engineers have developed a mission control computer with the following functionalities:

  • performing navigational calculations according to proprietary inertial navigation algorithms (INS);
  • rocket flight control;
  • ensuring telemetric and visual communication between the rocket and the ground control station at a distance of up to 100 km;
  • activation of the rocket pyrotechnic initiators.
