Verified Activities

Activities that were verified during Phases A, B, C, or D

V-COM-0621

Inspect the communications hardware and verify it does not have any sharp corner or edge in the chassis and in all accessible areas.

Not Verified: Phase D

V-COM-0630

Verify that the communications hardware outside of the cubesat have secondary locking features for all fasteners and subcomponentsha are not held captive by the spacecraft structure should it come loose.

Not Verified: Phase D, Integration

V-COM-0640

Verify that all communications components are electrically bonded per SSP 30245 Rev.E and ensure that the spacecraft is free from electrical shock and static discharge hazards.

Verified: Phase D

Compliance Notes: SSP 30245 Rev.E - 3.2.1.1.2 - The wire connecting to the ground plane will be soldered at one top corner of the ground plane. The bond surface preparation will be documented and and the Class R bond will be tested for impedece. 3.2.1.2.2 - NEARBY CONDUCTORS, Direct metal–to–metal contact is preferred, however, not required. 3.2.1.2.3 - SPACE STATION STRUCTURE, Vibration will be mitigated by using a non-conductive epoxy. 3.2.1.3.3 - CONDUCTIVE MECHANICAL SUBASSEMBLIES/PARTS, bleed–off path is not required as part of the antenna and ground plane. 3.2.1.2.1 - IMPEDANCE, the coaxial cables have a controlled 50 ohm impedence, the resistance matching circuit will be implemented to match the resistance of the antenna to maintain the same impedence. 3.3.2.1- JUMPERS/STRAPS, Bonding jumpers/straps will be kept short and direct and have a length–to–width ratio that does not exceed 5 to 1 ( wire tremination that comes from the coaxcable to the ground plane).

Evidence: No conductive path is from the ground plane to the structure is planned. The return path is insulated from the structure and bonded as per required specification. The path from the ground plane to the radio is the only return path that is planned for communication.

V-COM-0650

Verify that the communications system design uses a three-axis orientation system that is defined by Nanoracks.

Verified: Phase B

Evidence: Comms system used 3- axis orientation.

V-COM-0660

Inspect the hardware fasteners and verify that they have a thread size of 2-56, 4-40, or 6-32.

Verified: Phase D

Compliance Notes: All holes on the Comms board are made to accommodate imperial fasteners.

Evidence: Hold size.

V-COM-0661

Inspect hardware fasteners and verify that they have a hex head.

Not Verified: Phase D

V-COM-0670

Review the hardware design and verify that there are no pressure vessels or sealed containers with an internal pressure greater than 100 pounds per square inch absolute.

Verified: by inspection, Phase C

Compliance Notes: No sealed components on the comms board.

Evidence: CAD model doesn't show sealed vessels.

V-COM-0680

Verify that the communications subsystem is self-contained and does not need any operator activities or interference from integration to launch.

Not Verified: by inspection, Phase C

V-COM-0690

Review the communications electronics hardware design and verify that only ceramic capacitors are used.

Verified: Phase C

Compliance Notes: Only cermaic capacitors.

Evidence: UMS-0076_Schematic_v1.

V-COM-0700

Measure the mass of the FM components in the communication subsystem.

Verified

Compliance Notes: The board and transceiver is compliant. The mass of the transceiver reported by the manufacturer is <250 g.

Evidence: The measured mass of EPS board assembly with all its componnets is 52 gm which will be more than coms board!

V-COM-0710

Verify the datasheet of the individual component of the communication subsystem board.

Verified

Compliance Notes: No magnets used.

Evidence:UMS-0076_Schematic_v1 .

V-COM-0720

Verify individual components of the communication subsystem by reviewing the datasheet of individual components to check if any batteries are used.

Verified

Compliance Notes: No batteries used.

Evidence: UMS-0076_Schematic_v1.
