Welcome to the IEEE GRSS database of Radio Frequency Interference (RFI) observations and frequency allocations for remote sensing. These online tools are still under development and enable one to:

  • list RFI observations in tabular form and locate them on a map.
  • lookup and display frequency allocations, with particular attention to those for EESS (Earth Exploration Satellite Service);

Selection criteria include country or ITU region, frequency range or frequency band (according to IEEE designation), as well as date range.

A brief tutorial on how to use the RFI observations tool is available here

Funding for developing these web applications is being provided by the IEEE Geoscience and Remote Sensing Society.

The database of RFI observation has been made possible thanks to the contribution of the SMOS and SMAP project teams to the RFI observation database. It is not intended to cover all occurrences of existing interference affecting these sensors. In addition, RFI may still be present in other EESS bands, even if it is not reported here.
