The article is devoted to solving the problem of global control of the critical frequency of the ionosphere with the help of new domestic satellite «Ionosonde» included in the monitoring system developed by the ionosphere «Geophysics». Work installed at these satellites onboard ionosonde «LAERT» is defined programs and mode, specified as with the earth and formed on board the satellite. In the paper discusses possible options for deterministic and adaptive modes of ionosonde in relation to the changing ionospheric conditions and objectives of the experiment. It is shown that the competing demands on the frequency and spatial resolution for sensing from satellites need flexible modes based on a parallel dimension more information, including the radio noise from Earth sensing and data on previous turns. It is noted that the model forecast values f0F2 for IRI, when used in adaptive mode should be adjusted upwards in frequency by 2−3 MHz. To improve the reliability of the detection of quasi-wave disturbances in the ionosphere is proposed to increase the density sensing in space up to 20−30 km by increasing the pace and reduce the bandwidth sounding.
