Frequency Allocations in Remote Sensing

Frequency Allocations in Remote Sensing (FARS) Technical Committee

Mission

The Frequency allocations in Remote Sensing (FARS) Technical Committee goal is to interface between GRSS and the radio-frequency regulatory world by

  • Educating the remote sensing community on spectrum management processes and issues
  • Promoting the development of radio frequency interference detection and mitigation technology
  • Organizing technical sessions at conferences, workshops, etc. on the above processes, issues and technologies,
  • Providing spectrum managers and regulators with technical input and perspective from remote sensing scientists and engineers
  • Fostering the exchange of information between researchers in different fields, such as remote sensing, radio astronomy, telecommunications, etc. with the common scope of minimizing harmful interference between systems

Working Groups

The FARS Technical Committee organizes some of its activities in Working Groups to which all Technical Committee members are welcome to participate. If you are interested in joining any of the Working Groups below please send an e-mail message to FARS_WGs@grss-ieee.org indicating the particular Working Group in which you would like to participate in the Subject (e.g., “request to join [name of Working Group]” ) and briefly introducing yourself and your interest in the message body.


 

IEEE GRSS Views document on WRC-23 Agenda Items and other related topics relevant to remote sensing

Working Group Chair: Thomas von Deak

Development of GRSS document providing views on international regulatory issues affecting remote sensing operations, in particular

  • on World Radiocommunication Conference agenda items that could have a potential impact on remote sensing operations (excluding aspects related to satellite-ground communications)
  • on other ITU-R topics that could also affect remote sensing

Its purpose is to:

  • be a tool for GRSS members to familiarize themselves with these issues and participate in the development of GRSS views concerning them.
  • inform remote sensing scientists and engineers of these concerns so that they may engage in their administrations decision-making process  to consider the IEEE GRSS views.

IEEE Standard for Remote Sensing Frequency Band Radio Frequency Interference (RFI) Impact Assessment

Working Group Chair: Roger Oliva

Initiative between FARS-TC and IEEE Standards Association (SA) to develop IEEE Standards on the quality assessment of Earth Exploration-Satellite Services (EESS) frequency bands with respect to presence of RFI. 

Its purpose is to define:

  • how to quantitatively assess the presence of man-made RFI in EESS frequency bands
  • best practices to consistently document RFI affecting remote sensing missions


More information can be found at:  sagroups.ieee.org/4006/

Please join the RFI in Remote Sensing Working Group from the IEEE SA if you would like to participate, by registering interest at development.standards.ieee.org/myproject-web/app#interests. An account is necessary, but one doesn’t have to be an IEEE member.

FARS China Subcommittee

Chair: Dr. Mingliang Tao

Widespread Radio Frequency Interference (RFI) is being observed by remote sensing instruments over China, while many new sensors (both active and passive) are planned by China in the next few years. Under the umbrella of the GRSS FARS TC, the goal of the FARS China Subcommittee is to raise awareness of RFI issues in China, and serves as a global, multi-disciplinary network connecting Chinese engineers, scientists, and practitioners from related disciplines to foster further cooperation and collaboration. The China Subcommittee aims at supporting educational initiatives for both students and professionals, and at promoting advances in spectrum management as well as RFI detection and mitigation techniques, with a focus on China. A couple of key areas on which the subcommittee is currently focusing are:

  • Documenting RFI observations in China, providing spectrum managers and regulators with technical input and perspective from remote sensing scientists and engineers, and engaging in the regulatory development process in spectrum management.
  • Promoting RFI detection and mitigation techniques at different levels, ranging from mission design to a signal processing perspective, encompassing both active and passive remote sensors.

The FARS China Subcommittee invites everyone interested in contributing to contact Dr. Mingliang Tao for details on how to get involved.

Tools

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:
  • RFI Observation Tool:  List RFI observations in tabular form and locate them on a map
  • Frequency Allocation Tool:  Lookup and display frequency allocations, with particular attention to those for EESS (Earth Exploration Satellite Service)
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.
