Introduction
Test Description: Test the functionality and performance of flight model sun sensors. This test is based off of the sun sensor calibration procedure provided by the York University Nanosat Research Laboratory for the Iris mission.
Completed:
Documented by: Riley Sweeney
Resources Required:
Tools: Required tools such as cleaning equipment, chemicals, jigs, hand tools, etc.
Hardware and Equipment: UMS-0381 FM, UMS-0866 ADCS FM CCA, power supply, rotation table, collimated light source
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: R-LIB-ADC-033-6974
Pass Criteria: The sun sensors shall be able to determine the direction of a light source to within 1 degree.
Test Apparatus
Test Apparatus
This test will occur on the FM FlatSat.
Check the connections between PCBs on the FlatSat. The power PCB should be connected to a power supply with two wires for power and ground. This PCB should also connect to CDH using an intermodular connector.
The CDH PCB should have two intermodular connectors, one coming from the Power PCB, and one going to the AODCS PCB.
Sun sensor connects to the AODCS PCB using a ten pin connector. There are two ports on the PCB, SUN_SENSOR_1 and SUN_SENSOR_2. It is recommended that the first sun sensor test use SUN_SENSOR_1, and the second test use SUN_SENSOR_2.
