Wave-like disturbances, caused by the launches of the Soyuz and Proton rockets from the Baikonur site, have been studied using the algorithm of the space-time accumulation of variations in the total electron content (TEC). Ionospheric TEC responses, observed on four GPS arrays at a distance of up to 4000 km from the launch site, represent a quasi-periodic oscillation with a period of 15 20 min, duration of 30 40 min, and amplitude of 0.1 TECU. The propagation velocity of wave-like disturbances is 300 1400 m/s, which corresponds to the range of sonic and supersonic velocities at an altitude of the ionospheric ionization maximum. Wave-like disturbances of TEC are caused by acoustic gravity waves (AGWs) propagating in the Earth’s atmosphere over large distances from a source. It has been established that the rocket launch region and rocket trajectory active legs, when a rocket moves under the action of the second and third operating stages of a propulsion device, are responsible for AGW generation.
