Inertial Sensor Assembly (ISA) Inputs Calculated automatically in simulation Defined in gnc_1553_system_objects.ads 3 Sensors; 2 records per sensor Note that the output of the ISA is an input to EFCS ISA1_OUTPUT_DATA_M01 : ISA_OUTPUT_DATA_M01_TYPE; ISA1_OUTPUT_DATA_M02 : ISA_OUTPUT_DATA_M02_TYPE; ISA2_OUTPUT_DATA_M01 : ISA_.OUTPUT_DATA_M01_TYPE; ISA2_OUTPUT_DATA_M02 : ISA_OUTPUT_DATA_M02_TYPE; ISA3_OUTPUT_DATA_M01 : ISA_OUTPUT_DATA_M01_TYPE; ISA3_OUTPUT_DATA_M02 : ISA_OUTPUT_DATA_M02_TYPE;

Star Tracker Inputs Calculated automatically in simulation Defined in gnc_1553_system_objects.ads 2 Sensors Note that the output of the Star Tracker is an input to EFCS ST1_OUTPUT_DATA : ST_OUTPUT_DATA_T; ST2_OUTPUT_DATA : ST_OUTPUT_DATA_T;

Command Data Defined in gnc_ul_system_objects.ads Mode commands Attitude commands Provided to Control subsystem using Scripting language (Timeliner) in version given to you Can be changed using Timeliner script, or using software Look at mit-16-035_script.tls for script being used env_uplink.ads defines numeric codes for command data (see “defines” at the beginning of the script) Run tl_main.exe to compile a script It will prompt for input script (*.tls) No options are needed It will produce *.tlx as output (same name as input) Rename to cc_script.tlx for EFCS software to use it

Telemetry Data Should contain all data needed by Test Team Currently defined as follows gnc_hfe_system_objects.ads ATTITUDE_IB : ATTITUDE_IB_T; ATTITUDE_RATE : ATTITUDE_RATE_T; gnc_mfe_system_objects.ads SSF_USER_STATE : SSF_USER_STATE_T; ACF_COMMAND : ACF_COMMAND_T; gnc_cs_system_objects.ads GNC_CS_OUTPUT : GNC_CS_OUTPUT_T;

PPM Commands Used automatically by simulation Output from student-generated code Defined in: gnc_1553_system_objects.ads PPM1_COMMAND_DATA : PPM_COMMAND_DATA_T; PPM2_COMMAND_DATA : PPM_COMMAND_DATA_T;

Star Tracker Commands Used automatically by simulation Defined in gnc_1553_system_objects.ads 2 Sensors; 2 records per sensor Note that the output of the Star Tracker is an input to EFCS ST1_COMMAND_DATA : ST_COMMAND_DATA_T; ST2_COMMAND_DATA : ST_COMMAND_DATA_T;
