  • IGARSS 2006
  • Spectrum Management Activities in regards to
    IGARSS/FARS
  • August 2, 2006
  • Thomas vonDeak
  • NASA HQ Spectrum Management Office
  • Thomas.vonDeak_at_nasa.gov

NASA 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.

5

    2007 by the Spectrum Management community.
  • Subjects TBD

8
Space 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

9
Possible 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

10
Proposed 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

11
Proposed 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)

12
UN 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.

Activities 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
