Meeting between Tracker and
Flight Software
February 4, 2004
Decisions:
* All TKR housekeeping data
can be sent at the nominal frequency (~every 20s) to the space craft. The
downlink frequency will be much lower.
* The FSW SRS will point to
a TBD TKR document that defines red limits for TKR housekeeping
parameters. The values are given to FSW
by files. The format will be specified by FSW.
* If the a red limit is
reached, the FSW will initiate Safe
Mode which will shut down power to the instrument
* No diagnostic software is
required for the TKR
Tracker did not ask any
diagnostics function on board for TKR since all of such tasks can be done on
ground. Only temperature, voltages and currents will trigger autonomous action
on board.
Actions: For Event
Monitoring, Hiro will produce a write up by 18 Feb that includes:
* TKR paramaters to be
monitored
* parametric values, both direct and statistically derived, that
constitute an error or anomaly that needs to be detected onboard
* the action FSW should initiate for each error/anomaly
* For Charge Injection Calibration, Hiro will produce a write up
by 18 Feb that includes requirements for:
* ToT
* Threshold scan
Hiro will discuss with
Eduardo about these issues.
