2. Firmware

Writing code in C++ for Pyxida (the main flight computer) and CCB (Camera Controller Board), along with unit tests for themD.E.N.N.I.S. and supporting boards, along with all standard software testing procedures.

3. Kalman filter:

The sensor fusion algorithm. If you want to learn more about it, I recommend this video series.

...

Hardware Out Of The Loop Testing - a utility for running firmware on a non-embedded machine in a sandbox to verify correctness in simulated scenarios. Emulators-ish.

5. Groundstation:

Software in Python, used to monitor the rocket in flight. A lot of progress happened last year, so this is not on the critical path.

...

In charge of integrating all the pieces of hardware on the rocket, including:

  • D.E.N.N.I.S.
  • Pyxida
  • ^Supporting boards (camera, power, RF, etc)
  • PyxidaCamera board
  • COTS altimeters
  • Cameras

Also will focus on getting the cameras to work, with the new hardwired camera connections for power and feedback.

Overview

"Avionics" refers to the system that operates the electronic systems aboard the vehicle. These systems are commonly used to deploy recovery systems, collect data, send telemetry, and activate payloads. Avionics interfaces with many subteams
