Tracking Antenna 🗼

Tracking Antenna Tower

Status
colourGreen
titleMechanical

Yaw only looking good.

  • Will look @ 3s

  • Going to add some angle on yaw only

    • on pitch version, going to add default is level and ability to pitch up and down.

  • Building the antenna starting this week.

  • Using the tripod.

  • No counterbalance for the yagis (fine for yaw only).

  • HS 785 HQ, 8 rotation servo

    • gearbox is 1:7

    • will need calibration for this later (in software)

titleELECTRICAL

Integration almost complete. BMX tested, NEOM8 not tested.

PID not started….

Tracking Antenna Software

Status
colourRed
titleEmbedded Flight Software

  • integration code finished

  • have a blocker: not finding neo m8 but solved today

  • will warp up the integration test

  • continue on pid motor code

  • WILL WRITE UNIT TESTS

ELRS 📶

Gemini 📻

Status
colourYellow
titleELECTRICAL

  • Slightly behind schedule

  • Electrical schematic in its last stages

    • missing some connector clarifications

      • Planning to ask in ELRS discord

    • Research new component to replace PCB antennas

    • Will require a schematic review

      • Potentially other EE members or leads

      • Also planning to review in ELRS discord

  • PCB design phase hoping to start this week

  • Will ideally be able to give some dimensions and sync with mechanical soon for JR module mechanical design

  • Gemini communicates over UART.

  • Antennas for ESP are mostly meant to flash firmware over wifi / OTA updates

  • Going to do RS422 now, looking for Wireless in the future.

    • if doing wireless - it can be UART.

      • Gemini communication needs BOOT0 connection (to update over wifi).

        • may need to use push-button // jumper

      • Normal communication just uses UART.

  • Just started PCB phase

  • Image Added

    Board will likely not be ordered before the end of the term

    • Will need to be tested early next term

titleEMBEDDED FLIGHT SOFTWARE

< updates here >

  • Hardy looking to create wireless function for RS422, will contact Farris to get more info.

Ground Station Software

Status
colourPurple
titleAUTONOMY

  • Data Telemetry working & tested.

  • Working on GUI.

IMACS

  • working on testing stuff through TCP.

  • Once serial port working, and GUI done, need to test on drone // ardupilot.

    • Minipix possible?

QR Code detection

  • Focus rn

MAVLink commands

titleAutonomy

  • All tasks given out, architecture created and finalized.

  • all independent tasks completed by saturday.

  • week after is integration

  • flight test on saturday post next (22nd).

GeoLocation

  • Needs to be refactored.

  • Merge-odometry-and-detections module

Dronekit on Jetson

  • Dronekit on jetson PR just reviewed.

    • trying to keep in common repository (ground and airside). Reduces boilerplate.
