LISSA AODCS Flight Software in the Loop Test

Introduction

Test Description: Test flight build of AODCS software without flight hardware. All operating modes (detumble, sun-pointing, payload operations, orbital maneuver) are tested.

Completed:

Documented by: Riley Sweeney

Resources Required:

• Tools: Required tools such as cleaning equipment, chemicals, jigs, hand tools, etc.

• Hardware and Equipment: Iris part IDs that will be used in this test.

• PPE: Personal protection equipment for tests and environment (clean room smock, face mask, gloves, etc.)

Verification Activities: R-LIB-ADC-370-7003. R-LIB-ADC-371-7004. R-LIB-ADC-372-7005. R-LIB-ADC-373-7006.

Pass Criteria: Flight software shall include a detumbling mode (R-LIB-ADC-370-7003). 

Flight software shall include a science mode (R-LIB-ADC-371-7004). 

Flight software shall include a sun-pointing mode (R-LIB-ADC-372-7005). 

Flight software shall include a deorbit mode (R-LIB-ADC-373-7006).

Test Apparatus

These tests will occur on the FM FlatSat.

Test Set-Up

Preparing s-function for simulator:

Adding s-function to simulator:

1. In the Simulink model, open the "Satellite-Under-Test" subsystem.

2. The s-functions are located in this subsystem. Double click on the s-function block to open the block parameters.

3. Specify the s-function name, parameters, and modules as needed.
