I'd like\nto inform you about our satellite's operation.\n\nWe started a long-run (continuous 24hours) of the APD sensor at 11:30,\nJun 3 (UTC) and it will be turned off on 11:30, Jun 4(UTC). During the\nAPD is turned on, the APD status packet can be heard everywhere in the\nworld.\n\nFM packets are transmitted on 437.475MHz and packet formats are\navailable in the following web-page.\nhttp://lss.mes.titech.ac.jp/ssp/cute1.7/fm_mode_apd_e.html\n\n4A-51-31-59-54-43-3E-4A-51-31-59-43-5A-3A-D0-30-77-B8-03-16-99\nFor exapmle, according to an above APD status packet we can obtain\ninformations as;\n4A-51-31-59-54-43-3E-4A-51-31-59-43-5A-3A : Header(JQ1YTC>JQ1YCZ)\nD0 : APD Packet ID (Fixed)\n30 : Status Code\n\tAPD Status : Operational\n\tHV Status : Set Value = Output Value\n\tTemp Correction : Active\n\tData Mode : Counter Valid\n\tDetector : APD A\n\tAPD Gain : Gain 30\n\tThreshold : 219mV\n77 : Temperature\n\t0x77 = 119 -> (119/255)*91.712-48.569 = -5.7 [degC]\nB8 : High Voltage\n\t0xB8 = 184 -> (184/255)*396.5 = 286 [V]\n03-16-99 : Counter\n\t0x1699 = 5785 -> 5785 * 2^3 = 46280\n\nLatest TLE from NORAD is;\nCute-1.7 + APD II\n1 32785U 08021C 08154.79960534 .00000134 00000-0 24077-4 0 664\n2 32785 097.9934 214.7536 0014695 178.3289 181.7972 14.81362228 5275\n\nThough the observation data will be stored in FRAMs, we'd like to know a\nreal-time status of the APD during the observation. Your kind reports\nwill be highly appreciated!\n\nBest Regards,\nHiroki Ashida\nCute-1.7 + APD II\n-- \nHiroki Ashida <[email protected]>\nLaboratory for Space Systems\nDepartment of Mechano-Aerospace Engineering\nTokyo Institute of Technology\nTEL/FAX : +81-3-5734-2644\nRoom 554, Ishikawadai 1st Bldg, Tokyo Institute of Technology\n2-12-1 O-okayama, Meguro-ku, Tokyo, Japan\n", "attachments": [] }
