As I can read from your proposal, you also plan to contribute with clock data to the formation of TAI at the BIPM, which will allow you to realize locally UTC via UTC(IRNWT). However, contributing to TAI needs acceptation from the BIPM according to the following rules: - ISTRAC ISRO should agree with the Indian national metrology institute, the National Physical Laboratory (NPL India) on this new contribution to TAI. The BIPM can consider you participation only after receiving the acceptation from NPL; - ISTRAC ISRO should be equipped with atomic clocks; this request is fulfilled according to the description of your sites; - ISTRAC ISRO should operate time transfer equipment; GPS receivers adapted for time transfer, and/or a two-way satellite time and frequency transfer station (TWSTFT). On this aspect, we can provide you information on the adapted equipment. Please let me know on your progress in the discussion with NPL for the acceptance of ISTRAC ISRO contribution to TAI.

I am enclosing herewith my proposal for setting up the IGS stations at three locations in India which are owned and maintained by ISTRAC, ISRO namely DSNI, LCKI and PBRI. As the recievers are yet to be procured under this project for installation which is to be carried out soon, the site log details will be submitted in due course of time. At present GFZ is operating an IGS station at ISTRAC, Bangalore named as BAN2 station which is currently fully operational and maintatined by ISTRAC. All the required resources and funding are available for installation and operation of the IGS stations at ISTRAC . Kindly confirm the acceptance of my proposal and register the proposed station id's for the IGS station naming purpose. Please provide further guidelines and other procedures to be followed for the commissioning and acceptance of these three IGS stations from India.

Three new sites are proposed. a) DSNI The IGS station will be located at ISRO’s Deep Space Network (DSN) Facility at Bylalu, Bangalore, India, which is around 50 Km from Bangalore City on Bangalore-Mysore National Highway. DSN is housing the multiple Active Hydrogen Masers and Cesium clocks for the support of the Deep Space Mission network as well as Indian Regional Navigation Satellites. The DSNI is proposed to be co-located with the ISTRAC Precise Timing Facility, which will generate UTC (IRNWT) using the ensemble of atomic clocks and TAI time transfer from PTB, Germany. b) LCKI This site will be located in the central part of India in a place called Lucknow, Utterpredesh, India which will be around 1500 Km from Bangalore. The IGS station will be located in the ISTRAC Ground station complex. c) PBRI This will be located in the Port Blair Island, which will be 2500 Kms away from India. The proposed IGS station will be located in the ISTRAC Ground Station complex at Port Blair. 2) Is the station currently operating, or planned? If planned, when is the projected date it will become operational? These stations are proposed to be operational within 6 months i.e by third quarter of year 2008, subject to the approval from IGS. 3) What agencies are responsible for installing, managing, operating, and maintaining the station? ISRO Telemetry Tracking and Command Network (ISTRAC), a unit of Indian Space Research Organisation, Bangalore, India. 4) What is the expected operational lifetime of the station? How secure is the funding? The station will continue indefinitely and will also have the adequate support provided from ISRO's on going projects and hence has secured funding for entire life time of the project. 5) Will the station replace an existing IGS station? If so, what is the scheduled date of decommissioning? Does the new station offer more capability than the old one? No. It is the new proposal and expected to offer more capabilities due to the availability of the data thro' Indian Space Science Data Center. 6) Does/will the station meets all of the strictly required IGS site guidelines (http://igscb.jpl.nasa.gov/network/guidelines/guidelines.html)? Yes, it will certainly meet the IGS site guidelines. 7) What is the data delivery schedule? The data will be available to the world scientific community On-line thro' High bandwidth Internet access freely as per ISRO data distribution policy for the scientific research purpose. 8) Can you set the receiver for "all in view" tracking (including tracking of satellites set unhealthy)? Affirmative 9) Are there currently operating IGS stations within 1000km? Approximately how many? Does this site offer any capabilities the others do not? There are three stations viz 1) IISC, which is currently not operational in Bangalore, India. 2) BAN2 owned by GFZ and operated by ISTRAC at Bangalore, India currently Operational 3) NGRI at Hyderabad , India which is 700 Km away currently operational. 10) What IGS product or project will this site benefit, based on its location, instrumentation, and latency? All products of IGS will be made available and also will be used for IRNSS and other ISRO satellite missions support 11) Is this station intended to tie a national datum to the ITRF? Not applicable 12) Is there a web page associated with this site (please specify)? If not, please include a site photo or two with this application. Currently no web site assiciated with these stations, however the details of the organisation supporting this stations can be obtained thro' the following web sites http://www.isro.org, http://www.istrac.org 13) Is data available on a public server (please specify)? Affairmative. Free data access will be provided thro' standard access control procedures as per ISRO data access policy. 14) The proposed four-character identifier should also be included, but it remains proposed only until confirmed by the CB. Allowed characters are A-Z and 1-9 (numerals may not be used in the first character). You may perform an initial check of the availability using http://sopac.ucsd.edu/scripts/checkSiteID.cgi. If the result is "available" it is certainly available. If this web page indicates it "may already be in use," it might be available for permanent stations anyway. DSNI, LCKI, PBRI 15) A new 4-char ID is required if a site is moved to a new monument. The 4-char ID has a one-to-one relationship with a monument, except in the case that more than one receiver records data from one antenna.
