    Lowell Digisonde International manufactures and markets the Digisonde-Portable-Sounder-4D (DPS4D), the latest model in the DIGISONDE® series of advanced ionosondes built in Lowell since 1969. The Digisonde is an ionospheric radar that uses high-frequency radio waves for the remote sensing of the ionosphere and the DPS4D is the only commercially available ionosonde system that measures all parameters of the ionospherically reflected HF radio signals, and automatically calculates the local ionospheric electron density profile in real time.
    DPS4D, the world’s most widely used HF Radar system for ionospheric research and monitoring monitors the effects of space weather on Earth’s ionosphere, supporting communications and navigation satellite operations, and HF and VHF radiowave communication.
