Latest Ionogram from TDS

Note: The ionogram image above is updated automatically.

If the station name is absent in the ionogram image you see results of tests performed in Boulder, CO as preparatory steps for future TDS missions. These tests are usually performed with a single channel and do not involve echo detection and other upper-level Dynasonde analysis products. What you may see is a traditional amplitude-based image of ionospheric reflections that normally serves as a background for Dynasonde-style ionograms. To make the traces more visible one can copy and paste the image into application like IrfanView and decrease the gamma value.

Fourth TDS deployment site in Marina, California (August 2022).
 

Dynasonde is an advanced technique of ionospheric radio sounding, the only existing one that fully implements the phase-based methods of radio measurements. The Transportable Dynasonde System (TDS) is a complex of the newest Scion HF Radar ("VIPIR") and the data processing software Dynasonde Software Suite including its 3-D plasma density inversion procedure NeXtYZ.
 

First installation of TDS (October 2020) was at the Platteville Atmospheic Observatory, the historic site of the first-ever experiments on ionospheric heating and also the site of installation of the first prototype Dynasonde.
 

The panoramic image shows the central group of five (out of eight) receiving dipole antennas at Platteville and the specialized trailer serving as the shelter for radar electronics. One can also see the 33m high telescopic tower supporting a delta transmitting antenna.
 

Second TDS deployment was in Socorro, New Mexico (November 2020).
 

Third TDS deployment in Palm Bay, Florida (December 2021).
 

Using this page one can watch the current state of the ionosphere over TDS location. Comparison of the ionogram date and time with the current date and time shown above allows one to judge about an operational state of the system.
