News

GRSS sends a letter to the United States Congress. On July 20, 2021, the Committee on Science, Space and Technology of the United States House of Representatives held a hearing on Spectrum Needs for Observations in Earth and Space Sciences. FARS TC member David Lubar was among the witnesses who gave a testimony and answered questions from members of the Committee on Science, Space and Technology. The video recording of the hearing is available here. Following the hearing, the FARS Technical Committee prepared a letter that the GRSS President David Kunkee signed and sent to the Committee on Science, Space and Technology to serve as a Statement for Record for the 20 July 2021 hearing. The letter is available here IEEE-GRSS_Letter.

The FARS Technical Committee Advisor on Spectrum Management Thomas von Deak suddenly passed away on July 30, 2021, aged 67.

Thomas (Tom) von Deak suddenly and unexpectedly passed away on July 30, 2021, at the age of 67, in his home in Medina, Ohio. He is survived by his loving wife, Amanda, seven children and stepchildren, five grandchildren and three siblings. Tom graduated from Cornell University with an Electrical Engineering degree. He worked for more than 20 years at the National Aeronautics and Space Administration (NASA) Glenn Research Center in Cleveland, Ohio, during which time he was a spectrum manager in the NASA Office of Spectrum Management for 18 years. He was responsible for ensuring that all spectrum/regulatory aspects of NASA Earth science remote sensing program were addressed in the proceedings within the International Telecommunications Union - Radiocommunication Sector (ITU-R). Tom retired from NASA in 2018, and, along with being a consultant for the National Oceanic and Atmospheric Administration (NOAA), he became more and more involved in the Frequency Allocations in Remote Sensing (FARS) Technical Committee of the IEEE Geoscience and Remote Sensing Society (GRSS), participating in many of its activities. His contribution to representing IEEE GRSS and defending the interests of the remote sensing community at US national level and internationally at the ITU-R and the Space Frequency Coordination Group (SFCG) was invaluable. In 2020, Tom had also started getting engaged in the IGARSS 2021 organization with the planning of the FARS Technical Committee invited technical sessions. Tom had an optimistic personality and was always looking at the bright side even in negative situations. He was enthusiastic about his work and able to transmit his energy to those around him. He was a friend for many within the FARS Technical Committee. With his death, the remote sensing community has lost an exceptional champion and will be sorely missed. Thank you Tom from all your friends in the FARS Technical Committee and at GRSS!

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.

Response to US Federal Communications Commission (FCC) Notices

Working Group Chair: Paolo de Matthaeis

Objective of the Working Group is to follow activities of the FCC on issues relevant to remote sensing and if necessary prepare comments to submit to the FCC to represent GRSS interests
Working Group composition and focus will depend on the particular topic under consideration by the FCC

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.
