Add to ORKGA low power FM/CW ionosonde was constructed to investigate the vertical motion of the polar ionosphere. The most suitable pulse length is selected automatically according to the ionospheric layer height. Microcomputer control and data acquisition make it possible to select observation mode easily by changing software. A good deal of effort was made to eliminate interference with other observations and short wave telecommunications and by other emissions on neighboring spots
