LISSA FM Gyroscope Interface Test

Introduction

Test Description: Testing the interface between CDH and ADCS with focus on operating and configuring the gyroscope "in flight".

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: FM testing will likely occur in the clean room. Please follow all clean room safety guidelines. Please wear an ESD bracelet and use ESD mat when working with electronics.

Verification Activities: Provide a list of all verification activities that will be verified by the end of this test. It can be more than one if this is a multi-step test.

Pass Criteria: Provide a description of pass/fail criteria for each verification activity, including acceptance tolerances.

Test Apparatus

This test will occur on the FM FlatSat, using at least the FM CDH and FM AODCS PCBs.

1. Check if CDH is receiving power. This will either be direct from a power supply, or from the FM Power PCB.

2. Check if AODCS is connected to CDH using an intermodular connector. If not, connect the two (power and data).

Test Set-Up

With the FlatSat set up, this section focuses on connecting to the CDH and AODCS PCBs and setting up the necessary software.

Test Procedures

1. get gyro config

2. get some gyro data. you may rotate the PCB in a gentle (and repeatable) manner.

3. create struct to pass new config to gyro

4. set gyro config

5. get gyro config, verify settings change

6. get more gyro data. try to follow the same rotation as the first set of gyro data.

Test Close-Out

Include information about apparatus tear down, clean up, consumables storage, and how to store test data.

Data Analysis

Provide step-by-step instructions for data analysis, including location of data storage.

1. Create plots for both sets of gyro data.

2. Compare and contrast. These configurations can be transferred to the guidance system gimbal test to help improve its performance.
