Description

STIX has only 1 science acquisition mode, which is independent from solar activity, campaigns, etc.

Data acquisition operations onboard do change based on the incoming flux. The attenuator is automatically used during high solar activity to suppress the count rates, cadence can be changed too.

STIX does change the data processing and packaging onboard, based on solar activity and automatic event detection:

During non-flaring times: STIX FPGA accumulates background counts for energy calibration.

During flares:

When requested through TC: extra TM-ready packets can be selected and transferred to the SSMM for downlink.

 

EPS observation:

STX_NORMAL with parameter DATARATE = 600 [bits/sec]
