| Allocated TM | 0.7 kbits/s | |
|---|---|---|
| Download capacity per orbit | 226.8 MB OR 1270 MB | = 1.8144 Gbits (if only acquiring during 30 days) = 10.16 Gbits (if extrapolated to 168 days orbit) |

Observational modes
source:
For STIX there is only 1 data acquisition mode. Acquired science data are selected on-board autonomously (~500bps) or selected on-ground and retrieved via TC (~100bps).
Mode | Data Rate (bps) | Orbital Volume (Gbits) |
|---|---|---|
STIX Normal Mode - automatic onboard selection of data | ~500 | 7.3 (if acquiring full orbit) |
| STIX Normal Mode - TC-requested data | ~100 | 1.45 (if acquiring full orbit) |
| STIX LL | ~50 | 0.7 (if acquiring full orbit) |
| STIX HK | ~50 | 0.7 (if acquiring full orbit) |
Engineering modes & power consumption
Source: STIX EID-B Iss 5.0, Table 4.2 for power consumption incl. CDR margin and DC/DC conversion inefficiency.
Power allocation for STIX is 8W.
Mode | Datarate: HK+LL+SCI (bps) | Power consumption (Watts) |
|---|---|---|
| OFF | 0+0+0 | 0 (0) |
| BOOT | 0+0+0 | 4 (0) |
| SAFE | 50+0+0 | 2.41 (2.89) |
| MAINTENANCE | 50 + 0 to 50 + 0 to 600 | 3.2 (3.84) |
| CONFIGURATION | 50+50+0 | <6 (?) |
| NOMINAL(*), acquiring background data | 50+50+SCI controlled up to 500bps | 5.17 (6.20) |
| NOMINAL(*), during a flare | 50+50+SCI controlled up to 500bps | 6.83 (8.20) |
| NOMINAL(*), at strong flare peak: attenuator used | 50+50+SCI controlled up to 500bps | 13.08 (15.70) |
(*) Nominal mode is used for all science and calibration observations.
