MSP421
v5 v6 1 1 2 This segment covers the period from 8 December 2019 to 14 March 2020 (before the eclipse season as well as majority of time during eclipse season) and has 130% data volume as a baseline, however telemetry rate was increased in some orbits above baseline value. For the eclipse season the payload will be off, the eclipse times are: on SC3 and SC4 24/02/2020 12:00 - 15/03/2020 00:00 and on SC1 and SC2 are 24/02/2020 12:00 - 17/03/2020 00:00. During this eclipse season in order to accommodate BM1 requests for the Cluster /MMS conjunctions, payload will be switched on for the two periods which will be managed by ESOC: (i) 20/03/03 09:30 – 12:00, BM1 mode; (ii) 20/03/10 05:40 - 10:20 1h NM1 + 2.5h BM1+1h NM1. 2 This segment covers the period from 8 December 2019 to 14 March 2020 (before the eclipse season as well as majority of time during eclipse season) and has 130% data volume as a baseline, however telemetry rate was increased in some orbits above baseline value. For the eclipse season the payload will be off, the eclipse times are: on SC3 and SC4 24/02/2020 12:00 - 15/03/2020 00:00 and on SC1 and SC2 are 24/02/2020 12:00 - 17/03/2020 00:00. 3 4 During this eclipse season in order to accommodate BM1 requests for the Cluster /MMS conjunctions, payload will be switched on for the two periods: (i) 20/03/03 09:30 – 12:00, for 1.5h BM1 mode surrounded by NM1 mode; (ii) 20/03/10 05:40 - 10:20 for 1h NM1 + 2.5h BM1+1h NM1. 3 5 4 6 This segment includes a moon eclipse on C1, C3 and C4 on 24 January 2020, on C4 during the period 14:23 - 15:00; on C1 during the period 15:05 - 15:16; on C3 during the period 15:28-16:00. Due to the different power profiles, the moon eclipse impact for each spacecraft varies. On C1, which is not affected much, there is no constraints on the payload and TDA6 periods, payload will stay on. On C1 the WBD operations are not allowed during the period 24/01/2020 12:00-18:00. On C3, there will be 'Power Limited' platform configuration: with the CIS, PEACE, WEC and FGM instruments being off during the period 24/01/2020 15:00 - 16:30. In addition, there will be no BM1 and BM2 modes allocated during the same interval, and no WBD operations during the interval 24/01/2020 12:00 - 18:00. On C4, all payload will be switched off for the period 24/01/2020 06:00 - 25/01/2020 00:00, there will not be any BM1 and BM2 modes allocated during the period 24/01/2020 00:00 - 25/01/2020 and no WBD operations during the period 24/01/2020 00:00 - 25/01/2020 00:00. … … 9 11 10 12 '''The MSP42.1 was updated on 20/11/2019 in order to accommodate the February 2020 eclipse season start and the moon eclipse in January 2020. 13 14 '''The MSP42.1 was updated on 31/01/2020 in order to accommodate two BM1 intervals during the short eclipse season.
