Recent Developments at RTH New Delhi
Table Driven Code Form: RTH New Delhi is
transmitting daily Synop (on test basis) and
SATOB messages of Indian Region in BUFR
Format (Developed by IMD) to Tokyo through
GTS
Digital Satellite Broadcast of IMD through
Asia Star satellite has been changed to
multicasting
File naming server installed is providing
data to users through TCP/IP Socket, E-mail,
SMS and FTP in WMO File naming
conventions. It has also feature of OCR
(Optical Character Recognition) to extract
information from imageries.
GMDSS bulletin is also placed on IMD
website in real time.

Present Setup of IMD Communication
* SINGLE PATH VIA GROUP
OF NODES.
* DELAY DUE TO MULTIPLE
HOPS COVERAGE.
* MODE OF
COMMUNICATION:
TP/TELEX/TELGRAMS/HFRT
COSTLY.
* OLD AND OBSOLETE

Need for Modernization
DEPT. OF TELECOM IS WITHDRAWING TP/TELEX LINKS AND HAS ALREADY
WITHDRAWN FROM MANY PLACES.
DATA THROUGH TELEGRAMS REACHING VERY LATE.
HFRT (HIGH FREQUENCY RADIO TELEPHONY) IS OBSOLETE TECHNOLOGY AND
WORLD WIDE BEING REPLACED WITH LATEST TECHNOLOGIES AVAILABLE LIKE
SMS THROUGH MOBILE AND EMAIL SERVICES.
VPN IS LATEST TECHNOLOGY WITH ADVANTAGES OF CONNECTIVITY BETWEEN
ANY TO ANY IN COMPARISON TO DEDICATED LINKS WHICH IS CONNECTIVITY
BETWEEN ONLY TWO ASSIGNED LOCATIONS.
VPN LINKS ARE SECURED AND COST EFFECTIVE LINKS.
MOBILE DATA TERMINALS WITH ADDITIONAL DIAL UP MODEM IN BUILT UTILIZES
DATA EXCHANGE THROUGH SMS, EMAIL AND DIAL UP CONNECTION.
SMS AND EMAIL UTILIZES SIMULTANEOUS TRANSMISSION TO MULTI NODES THUS
DATA AVAILABILITY AT AMSS AND RTH ARE VERY FAST.
AT PRESENT IVRS SYSTEM IS AVAILABLE ONLY IN FOUR METROS. AS A PUBLIC
WEATHER SERVICE IVRS SYSTEMS ARE REQUIRED TO BE AVAILABLE AT ALL MET
CENTRES.
AS PER WMO REQUIREMENTS RTH IS REQUIRED TO EXCHANGE BINARY DATA IN
BINARY UNIVERSAL FORM (BUFR) FORMAT, IMAGERIES AND WEB PAGES WHICH
ARE AT PRESENT NOT SUPPORTED BY OUR EXISTING SYSTEM.
REQUIREMENT OF AMSS SYSTEM AT NAGPUR AND AMSS MODERNIZATION AT
GUWAHATI.
