RADIO ASTRONOMY INSTALLATIONS IN INDIA (1 of 3)
  • Map made for a paper presented in AP-RASC/J7
    during Aug 2001 is given again for continuity.
  • Guwahati University in the State of Assam in
    Eastern India has been recently included in the
    Map.
  • The location for the Cluster Antenna Array
    (PROPOSED) has been shifted from Bangalore to
    GMRT site in Maharashtra, Western India

Spectrum Management Activities by IRAS in
India 2003-04 (1 of 3)
  • Review and Update of the policy document on
    Indian National Frequency Allocation Planning
    (NFAP-2002), based on
  • the outcomes of WRC-03
  • Add-Mod-Del to spectrum requirements received
    from Government departments, private service
    associations, telecom industry and
  • Inputs from concerned wireless users
  • is in the penultimate stage of
    consolidation.
  • Participation by Venkat, Yashwant and Ananth
  • RAS CONCERN Incorporation of PPDR provisions as
    per Resolution COM5/4 WRC-2003, as a suitable
    Indian footnote in the New NFAP-2004 document
    with acceptable protection for RAS in 406.1-410
    MHz band. The current position of IRAS is to
    EXCLUDE the use of the RAS band for PPDR in India.

Spectrum Management Activities by IRAS in India
2003-04 (2 of 3)
  • Mr. B. Chaudhuri, Joint Wireless Adviser to Govt.
    of India, elected as Vice-Chairperson for ITU-R
    Study Group on Spectrum Management and
    Monitoring(SG-1) and Chairperson of ITU-R
    Working Party on Spectrum Management
    Methodologies (WP-1B) for the period 2003-2006
  • Preparation for WRC-07 CURRENT STATUS
  • The order to convene a national Preparatory
    Committee for WRC 07 has been just issued.
  • IRAS nominees to the Indian Working Parties for
    WRC-07 preparation
  • Uday, Venkat WP1 Spectrum issues
  • Yashwant, Venkat WP7 Space Science services
  • Ananth Special Committee on Regulatory matters

Spectrum Management Activities by IRAS in India
2003-04 (3 of 3)
  • Coordination for CorDECT type WLL system and 1.8
    GHz GSM operation around GMRT site
  • Coordination for GONETS satellite systems of
    Russian Federation, a network with a
    constellation of 36 satellites operates in
    312-315 MHz and 1642.5-1643.4 MHz in the Uplink
    and 387-390 MHz and 1541-1541.9 MHz in the
    downlink.
  • Conditional clearance with protective clauses
    was issued.
  • SFCG-23 Action Item 23/6 on the compatibility
    between EESS SAR systems at 432-438 MHz and RAS
    observations in the band 406.1-410 MHz
  • MIFR studies Summary Excel file available on
    request

RAS Instrumentation activities in India
2003-04
  • Upgrade of GMRT to cater to an instantaneous
    bandwidth of 250 MHz with seamless RF coverage
  • Cluster project TIFR's "Spectrum Interest" limit
    to be raised to 10 GHz from the current 1.4 GHz!
  • Indian Correspondence Group on RFI Mitigation
    Techniques
  • Omni-Directional RFI Logger at GMRT
  • University of Guwahati S-band receiver, in
    collaboration with ECRA
  • University of Gorakhpur 4 nos of 5 m. antenna
    for student training at lt 3 GHz RF

11
Spectrum Management Activities by IRAS in India
Future (1 of 2)
  • IRAS contribution to the activities of ITU and
    APG Study Groups for various WRC-2007 agenda
    items will be made preferentially through the
    Indian Administration. For items identified as
    time-critical, we hope to put our inputs through
    IUCAF/ RAFCAP.
  • The order of importance and priority for the
    efforts by IRAS on the above would be
  • AI 1.21 TG1/9 Band-by-band Studies at lt 1 GHz
  • AI 1.11 BSS in 620-690 MHz band vis-à-vis RAS in
    608-614 MHz.
  • TG 1/8 UWB transmissions and RAS
  • AI 1.17 RAS in 1400-1427 MHz band and MSS feeder
    link issues
  • AI 1.7 OH-band RAS and MSS allocation issues
  • AI 1.4 IMT-2000 issues and impact on RAS
  • AI 1.9 Transmit Space Stations in 2500-2690 MHz
    and RAS
  • AI 1.8 HAPS in 27.5-28.35, 31-31.3 and 47.2-47.5
    GHz ranges and RAS
  • AI 1.19 Globally Harmonized FSS frequency bands
    for internet and RAS
  • Draft question to SG7 to replace the ITU Res.
    701, suppressed in WRC-03.

Spectrum Management Activities by IRAS in India
Future (2 of 2)
  • PLT/ PLC/ BPL No discernible activity by
    interested lobbies at present. To be kept under
    watch!
  • IRQZ Government of India sensitized on the issue
    in early 2003 but needs a follow-up
  • (National/ International) School on Spectrum
    Management and RFI Mitigation Methodologies, to
    be held in Pune, India during early/mid 2005?????
  • URSI meeting New Delhi Oct 22-29, 2005
  • SKA meeting Pune Oct 31-Nov 4, 2005
  • Penultimate meeting of TG 1/9 to be hosted by
    India in 2006????
