IRNSS 1A India and the Indian Regional Navigation Satellite System have officially joined the GNSSS Global Navigation Satellite Systems Society With full membership however come some society duties and responsibilities Chief and first among these is to provide all other society With full membership in the GNSSS come some society duties and responsibilities members and interested parties with an interface control document ICD defining the characteristics of the signal transmitted from ones satellites to navigation receivers on the specified radio frequency ies IRNSS signal transmitters will operate in L5 band 117645 MHz and S band 2492028 MHz The system targets provision of an absolute position accuracy of better than 10 meters throughout the Indian landmass and better than 20 meters in the Indian Ocean as well as a region extending approximately 1500 kilometers around India Who needs an ICD now you ask Who wants to navigate the Straits of Hormuz or New Delhis traffic jams using one satellite No one of course But nearly every GNSS product developer designer and manufacturer has a vested interest in quickly getting their hands on such a document if they want to sell goods in India a market of very significant size Development design and manufacture cycles are long especially when you begin with new and unknown quantities such as a new signal in space IRNSS once posted a very aggressive schedule beginning in 2011 it planned to launch two satellites per year to achieve a full constellation of seven by the end of 2014 Of course it has fallen a bit behind that curve with first launch in 2013 This would push its operational date to end of 2016 Not all that far out As our OEM editor Tony Murfin wrote last year in a BeiDou context developers are building digital signal processing application specific integrated circuits with so called generic reconfigurable channels to accommodate future add ons but RF front end hardware and signal processing software still require lengthy research and development Generic DSP channels and associated software decoding algorithms may not be generic enough for all the things that might await in new modulation schemes yet to come online So its not just rabid intellectuals like the Noble New Brunswegian my friend colleague and GNSS mentor and our intrepid Innovation columnist who prodded me up on this bully pulpit to ask O India where is thy ICD The worlds breadth and depth of GNSS wants to know GPS World August 2013 www gpsworld com 6
