Information about the I-Boom deployment operation during the LEOP.
RPW sub-system teams will also contribute to define the RPW modes to be set during the deployement.

Fig. 1. I-Boom operation timeline
In this phase, RPW measures the noise of the platform. RPW is set in a single specific configuration for I-BOOM deployment. Measurements will be also taken during the first and last 10 minutes before and after the IBOOM deployment. RPW in SURVEY_BURST SCIENCE submode with both spectral modes (all frequencies for B) and waveforms. The instrument is expected to be switched off before and after the operation.

The table below gives the organization of the operation stages and associated timing.
Activity | Step | Description | Time since beginning |
|---|---|---|---|
| Instrument initialization | A | RPW switch on and go to I-BOOM mode/configuration | 0 min |
| I-BOOM deployment data acquistion and visualization | B | Beginning of the I-BOOM deployment | 10 min |
| I-BOOM deployment data acquistion and visualization | C | End of the I-BOOM deployment | 130 min |
| Instrument switch off | D | RPW switch off | 140 min |
The table below gives the RPW modes and configurations (i.e., states) expected for each step of the operation timeline.
First step | Last step | RPW configuration | Duration | Comment |
|---|---|---|---|---|
| A | D | RPW_NECP_IBOOM-DEPLOY_CONFIG1 | 140 min. | A single configuration will be used during the entire operation timeline. |

The DPU SCIENCE SBM_DETECTION submode can be applied on-board during NECP, but there is not guarantee that the resulting SBM data stored on the SSMM can be downlinked to ground by MOC during this phase. (Note that the dump of the SBM data by the DPU can be forced by TC, since in the nominal case the transfer of data from the DPU SBM buffers to the SSMM is only done when an event is detected on-board.)
