Ionospheric Sounding System for Space Weather Disaster Preparedness
Ionospheric Sounder
An Ionospheric Sounder is a precision instrument that monitors key parameters of the Ionosphere—located approximately 60 km above the Earth—such as electron density, altitude, and critical frequency, all in real-time. This observation enables accurate prediction and analysis of the effects of space weather changes, like solar activity, on radio wave propagation. The collected data is essential for predicting the quality of High-Frequency (HF) communication and for correcting errors in GPS and satellite navigation systems. Thus, the sounder plays a crucial role in securing a stable wireless communication environment, national security, and scientific research fields.
Ionospheric Sounder
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.
