Some notes/issues from the assembly are listed below.

• The hinge that attaches to the antenna bucket (and to which the antenna door attaches) is designed slightly incorrectly. It only has one screw which allows it to rotate about the axis of the screw.

• This meant that during final assembly, when the antenna hinge is installed such that its edges aligns with the edges of the bucket (to which it attaches), the antenna door tilts slightly downwards.

  • This results in a gap on the between the antenna door and top surface of the antenna bucket when the door is closed while on the bottom side, the antenna door extends beyond the antenna bucket's bottom surface.

  • This tilt is enough to prevent the antenna bucket from installing into the COMMS shell since the door hits against the shell and will not open through the opening on the shell

• To fix this, we had to install the hinge loosely so that it could rotate about the screw and perform the whole antenna bucket assembly step. Once the bucket was installed in the COMMS module, we had to open the antenna door and remove the screw that held the antenna door on the antenna hinge so that we can access the screw that holds the hinge to the bucket (this is the screw we had to install loosely). Then, we tighten this screw in its current position and then install the antenna door and spring back into the antenna bucket. During this process of removing the antenna door, the bucket is still installed in the COMMS shell using the two of the three screws that are used to mount the antenna bucket to the COMMS module.

The antenna bucket assembly weight (not including the antenna or the COMMS module) was: 25.25 grams

Some notes/issues from the assembly are listed below.

• During masking, we forgot to mask out the area where the self-adhesive zip tie holder be installed. We had to remove the conformal coating for the zip tie holder after it had cured.

• We are missing a location for installing the connectors from the open end of the Coax able (this is the end that will result in two lose wires that solder to the antenna).

  • We will have to remove conformal coating to install these connectors

  • We will install these connectors on the Comms board on the opposite side from the burn wire and resistor holders on the board and route the loose ends of the wires underneath the antenna bucket and solder them onto the antenna

Some notes/issues from the assembly are listed below.

• During CDH software testing, we realized that we needed couple extra JTAG signals to code the CDH board through the umbilical. However, the umbilical pins were all being used so we had to extend the extra signals to an opening on the COMMS/CDH shell.

  • We soldered cables to the CDH board for the extra pins

  • We epoxied half the cable length to the CDH board and left the other zip tied to the shell

  • When the CDH needs to be programmed, the zip ties can be cut and the cables can be pulled out through an opening on the shell.

    • The CDH can be programmed

    • Once completed, we will cut the wires close to the epoxied region so that they do not extend outside the shell

    • Lastly, we will apply non-conductive epoxy to the open ends of the cables so that they do not short anything on the board.

** The CDH watchdog cables (see here for details) are also going to be connected in this manner before integration **
