PW-Sat

It will be the first entirely Polish satellite (cubesat). The goal is to check the influence of a balloon on a trajectory of the satellite. The altitude is not known at this moment. It depends on the provider that will agree to put our satellite into space. Usually cubesats can be found between 600 km and 800 km above the surface of the earth but the expected resistance of very sparse gases is not high. 200 km - 400 km altitude would be better but it is harder to find a appropriate provider. For some time cubesat will fly freely at a speed of about 8 km/s. One wall of the cube will open and a balloon will be released. It will be slowly filled by a gas. We expect that it will slightly slow down the satellite and the altitude will be lower and lower. Of course it will be a very slow process. After a few months cubesat’s altitude will be so low that it will burn in the atmosphere.
