Argonia Avionics Components

Argonia Avionics Components

Overview

Both the booster and sustainer bays will have the same components and layout. Each bay should have a PAL, Blue Raven, Tracki, 2 small PDBs, 2 screw switches

Components

PAL 9K6

  • Purpose: Parachute deployment, telemetry, stage sep (on booster),

  • Needs: Pressure, RF transparency (for GPS and telem antennas)

  • Orientation: Antenna up or down (prefer down)

  • Size: (Board only): 1.25” x 3.25”

    • antenna mount sticks from one end, see cad model for exact dimensions. This connector connects to a flexible ~2” cable which connects to the antenna

  • Antenna: - Assume we will use the detachable stubby antenna (~4” long). We could switch to an external antenna after more testing. Need link/dimensions for stubby antenna

  • Mounting: holes in 1” x 3” rectangle, 4-40 screws (Same as TM)

  • Other: Keep usbc port accessible if possible

  • Model:

Blue Raven

  • Purpose: Parachute deployment, stage sep, motor ignition, altitude measurement

  • Needs: Pressure, “Avoid direct sun.”

  • Orientation: Any

  • Size: 1.77” x 0.79”

  • Antenna: None

  • Mounting: Holes diagonal, spaced 1.15” x 0.15”, 4-40 screws

  • Model: (Just the Blue Raven Altimeter, not the other files)

  • Reference:

Tracki Cellular Tracker

Big Red Bee

Alternate backup tracking, would replace Tracki if there’s no cell service. If it’s complicated to get it to fit in the same space we can probably go without it.

  • Mounting: 3 screw holes in a 16mm x 370mm rectangle. Screws are something smaller than 4-40

  • Orientation: Doesn’t matter

  • Antenna: 7” wire whip, it can bend/go wherever

  • Model:

PDB Lite

  • 2 Per AV Bay

  • Purpose: Provide combined power/pyro power to one avionics board, and allow for remote arming/disarming over wifi

  • Needs: RF transparency (for wifi)

  • Orientation: Doesn’t matter as long as all screw terminals, buttons, and usbc port are accessible

  • Size: 43.2mm x 27.9mm (1 battery per board, permanently attached by short wire)

  • Antenna: Wifi antenna is integrated into the board

  • Mounting: 2 4-40 screw mounting holes, see cad model

  • Reference:

  • Model:

“depth” is the clearance required from the bay structure to the top of the components on each board

Switchboard

  • 2 Per AV Bay

  • Purpose: Provide combined power/pyro power to one avionics board, and allow for switching using some kind of physical switch

  • Orientation: Doesn’t matter as long as all screw terminals are accessible

  • Size: 35.6mm x 21.6mm (1 battery per board, attached via JST connector)

  • Mounting: 2 4-40 screw mounting holes, see cad model

  • Model:

“depth” is the clearance required from the bay structure to the top of the components on each board

Screw Switch

  • Location: 2 in each bay (1 per PDB)

  • Purpose: Turn AV on/off

  • Needs: Access to outside of rocket (will be a hole in airframe)

  • Size: (ask Owen)

  • Mounting: 2 screw holes (see CAD)

  • Model: Hannah found this model, pretty sure it’s right but someone should double check the dimensions

Camera:

TBD but likely something like this:

Hawkeye Firefly Whoop 4K 170 Split Camera V4.0 with Gyroscope output enhanced version 3D HD anti-shake for RC FPV Racing Drones (4K Split V4.0)

Location: Only in sustainer

Requirements: The circuit board will need to attach to AV Bay but the lens will need to go flush against the airframe

Wiring Diagram

Other Notes

  • Leave clearance for things that need to fit together!!! (PDBs, threaded rods, etc)

  • Include places to secure/zip tie wires

  • Leave at least 10mm clearance from all screw terminals, so there is space for the wires. Leave more space (15mm) if possible

  • Heatset holes:

  • Preferably don’t bend the antennas

  • There must be space under the boards, we typically use [list the sizes] spacers

    • Large spacers: 6mm

    • Small spacers: 1/16” (we stack at least 2)

  • See RRC3 Manual for pressure port sizing

Stuff we’re not using

RRC3

  • Location: In booster

  • Purpose: Parachute deployment (backup), stage sep

  • Needs: Pressure

  • Orientation: Doesn’t matter

  • Size: 0.925” x 3.92” (23.5mm x 99.5mm)

    • ~18mm depth

  • Clearance: 1/8” below

  • Antenna: - None

  • Mounting: holes in 11/16” x 3 21/32” (17.48mm x 92.84mm) rectangle, 4-40 screws

  • Other: Wires come out the screw terminal on either end so leave space

  • Model:

  • Reference:

Telemega

  • Location: In sustainer

  • Purpose: Parachute deployment, telemetry, motor ignition

  • Needs: Pressure, RF transparency (for GPS and telem antennas)

  • Orientation: Antenna up or down (prefer down)

  • Size: (Board only): 1.25” x 3.25”

    • ~16 mm depth

    • Wire antenna sticks out of one end

  • Antenna: - 7” wire antenna, attached to end of board

  • Mounting: holes in 1” x 3” rectangle, 4-40 screws (Same as PAL)

  • Other:

  • Model:

  • Reference:

Original PDB

  • Location: 1 in each stage

  • Purpose: Provide power/pyro power to both avionics boards, and allow for remote arming/disarming over wifi

  • Needs: RF transparency (for wifi)

  • Orientation: Doesn’t matter as long as all screw terminals, switches, and usbc port are accessible

  • Size: (Board only): 50mm x 45mm (1.97” x 1.77”)

  • Antenna: Wifi antenna, 31mm x 13mm x 1mm rectangle attached by flexible cable. We usually just tape it on

  • Mounting: PDB, wifi antenna, and batteries should be mounted on a sled that can slide into the av bay.
