For many years mobile communication system Iridium remains operational in orbit. In this article we analyzed Iridium constellation and satellite vehicles maneuvers in orbit. The results shows that some satellites remains active in orbit for 1318 years. Almost 7 years since Iridium 33 collision with Cosmos 2251 threat of collision with space debris still stands for Iridium space vehicles.
