Page 49 This gives the results in a total of 90.58 Mbit of sensor data generated during the entire flight. All sensor data generated on board the FISH will be stored on the local SD-Card and transmitted to the MAIN Payload at the same time. On the SD-Card, which is located on the MAIN Payload both the sensor data received from the FISH as well as the locally collected data will be stored. That amount is: 58.7912MBit 7.3489MByte on the FISH and 8 31.763448MBit 7.35489MByte 11.32MByte 8 This amount of data is stored on the memory cards on board the FISH and the MAIN Payload. 3.3.8 Power Budget The Power Budget is shown in Table 3.5 for the FISH. More details may be found in Appendix 3.

This is valid for 3 packs connected in parallel, so in case of one battery pack failure the system will still be able to operate for 3.75 hours which is 75% of the total operation time.
