Session Notes for RD1102 Prepared by D. Behrend, NVI, Inc./GSFC =========================================================== PURPOSE AND GENERAL NOTES =========================================================== The purpose of rd1102 is to test 512 Mbps recording mode as the anticipated mode for CONT11. This frequency setup uses 2-bit sampling with no fanout and 32 tracks. This mode was already planned to be used with RD1101, but a sked catalog error resulted in the selection of a 64-track mode. The schedule was generated using SNRs of 25 at X-band and 20 at S-band for all stations. All stations have been fully scheduled except Tsukuba as it was uncertain if they would be able to observe. The schedule uses a selection of 120 sources from the good geodetic source list. The minimum subnet size was set to 3. Kokee and Wettzell will observe INT I11088 during the time from 1815 UT to 1945 UT. =========================================================== Experiment: RD1102 Description R&D-02 2011 Scheduler: NASA Correlator: HAYS Start: 2011-088-17:30:00 End: 2011-089-17:30:00 Current yyyyddd: 2011088 (2011.24) ( 15650 MJD, TUES 29MAR.)
