all satellites operate at altitudes from 500 km, with many countries , including the usa, china manya japanlso trying to take a place in space up to 200 km, but in fact today, uh, these heights are not occupied. why is it that at these heights uh, is influenced by the residual atmosphere and free-flying body converges orbit for a few days, the existing correction engine. uh, they'll have to work constantly and they'll quickly use up what they take from the ground. the stock of the working fluid, and the orbits will also converge. we have created an engine that uses the residual gases of the atmosphere as a working fluid. in addition, we have created a platform for mass production of cheap e small-sized satellites for altitudes of 150-200 km. such satellites will weigh 10-20 kg and operate in orbit, e, from 5 years to 5 years and more uh, so we did a test on our own? bench for its bench equipment, as well as on the professional equipment of the kaliningrad torch - this is the state corporation roskosmos, the results of our development, truly breakthrough at the world level and their speedy i
