Instead OLSG will do some additional work, but minimal, between now and IOP-3 in the summer of 2013. The IOAG requested an updated roadmap, an estimate of the effort needed (financial resources) for CCSDS standardization that is required, and for the OLSG to produce a reduced set of core optical communication standards recommendations. At the IOAG, a reduced core set was discussed to be something along the lines of:</span> <br><span style='font-family:"Calibri","sans-serif"'> </span> <br><span style='font-family:"Calibri","sans-serif"'> Downlink Modulation (PPM, BPSK, DPSK)</span> <br><span style='font-family:"Calibri","sans-serif"'> Meteorological Measurements</span> <br><span style='font-family:"Calibri","sans-serif"'> Protocols</span> <br><span style='font-family:"Calibri","sans-serif"'> </span> <br><span style='font-family:"Calibri","sans-serif"'>However, the IOAG really asked the OLSG to go back and look at it and come back with a recommendation.
