q Start the switch of RAPID into the OFF mode at the beginning of the RAPID OFF periods unless the transition to the OFF mode overlaps with an OAI. In that latter case complete the switch into the OFF mode at the start of the OFF period.
q The RAPID OFF periods are the RAPID OFF periods requested by ESOC (see note below).
q Extend the period as described in section 1.6.
q Note: ESOC can request that some experiments are in a particular mode during a particular time window. Such mode requests appear in the MSP and the JSOC must command the experiment accordingly. Typically, they are experiment switch off requests that are issued in order to save power during long eclipses.
q Complete the switch of RAPID into the STANDBY0 mode at the beginning of the RAPID STANDBY0 periods.
q The RAPID STANDBY0 periods are the portion of the short eclipse periods that do not overlap with the previous mode periods.
q Extend the period as described in section 1.6.
q Complete the switch of RAPID into the STANDBY2 mode at the beginning of the RAPID STANDBY2 periods.
q The RAPID STANDBY2 periods are the portion of the manoeuvre and RAPID radiation belt periods that do not overlap with the previous mode periods.
q The manoeuvre periods include:
· The firing periods which starts 1h before the firing of the thrusters and ends 8h after
· The OAI intervals that overlap with at least one firing period
· Extend the period as described in section 1.6.
q Complete the switch of RAPID into the STANDBY1 mode at the beginning of the RAPID STANDBY1 periods.
q The RAPID STANDBY1 periods are the portion of the OAI periods that do not overlap with the previous mode periods.
q Extend the period as described in section 1.6.
q Start the switch of RAPID into the HIGH mode at the beginning of the RAPID HIGH periods.
q The RAPID HIGH periods are the periods complementary to the above Mode periods.
q Request that the transition to the HIGH mode is completed by the switch into the NM1 mode for the HIGH periods of which start time belongs to a BM3 period.
q Note that each time RAPID goes from the OFF state to one of the operational mode, the instrument is by default set for NM1,NM2,NM3 and BM2. If it happens that RAPID will go from OFF to one of the operational mode in BM1 and BM3 then special IBMDs will be required.
q The OFF and STANDBY periods have to be extended up to the end time of the next BM3 mode if the time duration between the original period end time and the next BM3 end time is less than the duration of the IBMD used to execute the transition into the HIGH mode. This is to avoid that the execution of the IBMD used to enter the HIGH mode overlap with a BM3 period. Such periods overlap can create an IBMD overlap since, at the start and end of the BM3 windows, it is requested to execute the technical adjustments that sett RAPID in and out of the BM3 intervals.
q Start the execution of the bm1 switch at the beginning of the BM1 OR
q Complete the execution of the bm3 switch at the beginning of the BM3 OR
q Start the execution of the hv_up_config switch at the beginning of the BM3 ORs that do not start at the same time than a HIGH period.
q Note that
the NM1 ORs include the NM1 ORs as well as all the
q Execute the nm1 switch at the beginning of all NM1 periods that do not:
· Start after an OFF period (by default RAPID is switched into a nm1 mode following an OFF period)
· Immediately follow an OAI region inserted in between two NM1 periods. Indeed, if, during the OAI RAPID was ON then it is already switched into the right OR mode. There is no need to duplicate the technical adjustment.
· Start after a BM3 OR that starts at the same time than a HIGH period; to avoid IBMD overlapping.
· Complete the execution of the nm1 switch at the start of the NM1 OR if the NM1 OR follows a BM1 OR; Start the execution of the nm1 switch at the beginning of the NM1 period otherwise
q Complete the execution of the nm3 switch at the beginning of the NM3 OR
