4NASA Spectrum Management Office
- SMO represents the interests of NASA in the
domestic (US) and international (UN ITU-R)
regulatory venues. - Remote sensing depends on rf bands which allow
measurement of the desired rf characteristics in
those bands. - Interference from man-made sources of rf
generally prevent that from happening - Changes in regulations regarding the use of
applications in band are a real threat!!! - RLANs in the 5 GHz region, UWB in the 23.6-24 GHz
region - Improved interaction between the Spectrum
Management community and the remote sensing
community can be beneficial.

8Space Frequency Coordination Group (SFCG)
Possible Space Frequency Coordination Group
(SFCG) interaction with IGARSS/FARS
- Membership Any national or international space
agency which is interested in the cooperative
development of recommendations for frequency
management matters in the support of science
services - 25 Members (Civil space agencies including NASA,
ESA, and NOAA) - 7 Observers (Including WMO, ITU-R SG 7, IUCAF)
- Purpose
- Supplements the ITU-R process on matters related
to national/international scientific space
agencies - Pre-coordinate national activities related to
science services
9Possible Space Frequency Coordination Group
(SFCG) interaction with IGARSS/FARS(continued)
- Probable IGARSS/FARS representation at the
SFCG-26 meeting in Bonn, Germany September 19-27,
2006 - First two days appropriate
- Discussion at the SFCG-26 regarding the use of a
SFCG rapporteur to the IGARSS to establish a
mechanism of interaction between IGARSS and SFCG. - Decision has to be made by the membership.
- Possible meeting of SFCG-27 in conjunction with
IGARSS 2007 - 50/50 chance of happening
10Proposed Spring 2007 Workshop on the Impact of
Remote Sensing on Commerce and the Public
(working title)
- Intent of Workshop
- Bring together
- Users of remote sensing products
- Remote sensing experts
- Regulatory bodies
- NTIA
- FCC
- Provide information
- The current and future remote sensing products
- The value of those RS products to commerce and
the public - The ability of the RF environment to support the
continued effective remote sensing operations - Discuss appropriate future actions
11Proposed Spring 2007 Workshop on the Impact of
Remote Sensing on Commerce and the Public
(working title)
- Organizing Committee
- Department of Commerce, NASA, NOAA, IGARSS FARS,
others as appropriate (not a closed group). - October 25, 2006 Fairly detailed plan and
Approval - April 2006 Workshop
- Washington DC area (probable)
12UN ITU-D Study Question on the application of
remote sensing technology in the area of disaster
management.
- The killer application.
- UN ITU-D Study Question
- Show linkage between the RF bands, the sensors
operating in those bands, the products of those
sensor operations, and the disaster modes that
those products are applicable to. - Outline the distribution mechanism(s) that are in
place delivering the RS products to the
appropriate entities. - Output
- A report maintained by the UN ITU-D that is
referred to by administrations. - Require the assistance of the RS community to
properly answer the question and revise the
outputs in the future. - An ongoing relationship between IGARSS/FARS and
SFCG facilitates this process.

16Activities March July 2006
Mission and vision membership activities
- FARS member participation in NOAA Organized
Workshop on Passive Microwave Sensing, June
13-14, 2006 - The purpose of the workshop is to continue the
verification of the list of passive bands found
in the International Telecommunication Unions
recommendation SA.515 - Reaffirming bands below 275 GHz and describing
uses in detail is a focus - For bands above 275 GHz, the information in Rec.
SA.515 is a recent (2003) addition now is the
time to make any necessary changes to band center
frequencies, frequency bandwidths, and
applications. - A most up-to-date list of passive sensing bands
(i.e.ITU-R Recommendation SA.515) must be in
place when the ITU expands the Table above 275
GHz if passive allocations are to be included
properly in the Table - Several FARS members participated in the workshop
17- FARS member participation in NOAA Organized
Workshop on Passive Microwave Sensing, June
13-14, 2006 (Contd) - Full day of presentations covering NWP status,
RFI thresholds, sensitivity vs. frequency and RFI
mitigation - Use of passive microwave data for numerical
weather prediction and interference thresholds - Optimum frequencies for precipitation include
bands that have no allocation/protection - Sensitivity to moisture/precipitation near 40 GHz
- Model-based results
- Discussed spectrum needs for temperature profile,
moisture profile and precipitation - Development of passive-users handbook to help
spectrum managers - One more similar workshop TBD
- Continue discussion on spectrum needs 89 GHz and
