Command List

The Command List data are time series records taken over the course of a day. Data files are labeled with the date. Individual records are a single data collection interval, which lasts approximately 20 seconds. Command List data are records of the commands issued to the file interchange system (FIS) for up-link to the spacecraft and executed by the CEB. The Command List data are a record of the commands that have been sent to or executed from the spacecraft and the associated timing information. Command data are produced whenever a command is executed. Timing information is stored with the commands, indicating when the command was sent to the spacecraft, the time the command should have been executed, and when the command was executed.

Column Descriptions
Column Name Type Bytes Units
CMD_ID MSB_UNSIGNED_INTEGER 2
ID of the command that was sent to the FIS.
OPCODE MSB_UNSIGNED_INTEGER 2
Opcode of the command. See Label for values.
FIS_CMD_TYPE MSB_INTEGER 1
Flags whether command is interactive (1) or not (0).
FIS_SEND_TIME CHARACTER 23
UTC time when the command was sent to the FIS, stored as yyyy-mm-ddThh:mm:ss.sss.
SC_SENT_TIME CHARACTER 23
Approximate time command was sent to the spacecraft, stored as yyyy-mm-ddThh:mm:ss.sss.
GRS_EXEC_TIME MSB_UNSIGNED_INTEGER 8
CEB time when command was executed.
TIME_ORBIT MSB_UNSIGNED_INTEGER 8
The time or orbit/pixel at which the command should be executed. If TIME_ORBIT_FLAG is true, lowest two bytes contain the pixel, next two bytes contain the orbit. If TIME_ORBIT is zero, the command is to be executed immediately.
TIME_ORBIT_FLAG BOOLEAN 1
True if the command to be executed by orbit/pixel, false if by time value.
DELAY_FLAG BOOLEAN 1
If non-zero, this a delayed command, to be executed at the time or orbit value given in TIME_ORBIT.
PARM1 MSB_INTEGER 2
First command argument.
PARM2 MSB_INTEGER 2
Second command argument.
PARM3 MSB_INTEGER 2
Third command argument.
EXEC_CODE MSB_INTEGER 2
Completion code for command. If the command executed with no errors this value will be zero otherwise it will the error message id (MSG_ID) of the last error that occurred.
