The Avionics team is currently working on 'AV3' class hardware and firmware for the Launch Vehicle No. 2c airframe. The AV3 hardware includes a PowerPC flight computer, a USB-based avionics bus, and a half-dozen USB-based avionics nodes including a GPS, IMU, power system, recovery node, and amateur TV broadcast.
- If you're new to the avionics team, or you want some information on a previous sytem, please see our Introduction to PSAS Avionics Page, and then see our list of project ideas below.
- For more in depth reading about the avionics nodes, see the 2006 Capstone Project Final Report (CapstoneLV2bProjectReport).
These projects are undergraduate engineering capstones that PSAS has sponsored:
- Capstone 2010 project: Flight computer carrier board
- Capstone 2009 project: The Avionics Power Supply (APS)
- Capstone 2006 project: The node 4 generic front end
Avionics System version 3
Here are the current subsystems in the AV3 avionics system:
- PowerPC Flight Computer
- PPC Flight Computer Carrier board
- AV3 Generic Front End
- AV3 battery pack
- AV3 battery board
- AV3 GPS system
Deprecated and unorganized subsystems:
- PV-700 Digital Video Recorder
- ARTS-2 Flight Computer
- The whole to do list
- New LV2c recovery node
- IMU Calibration
- LPC USB Isochronous Mode
- Avionics to-do list
- Avionics to-get list
- Bob-4 Video Overlay Board
- Airframe Test Computer Info
The 2006 Capstone student team has finished their 2006 Capstone Project.

From Spencer Webb of AntennaSys:
- Webb's Law of Project Complexity: "All good projects go from simple to insanely complex, then back to simple after a required epiphany."
- Corollary to WLPC: "If the project never gets to the insanely complex stage, it is probably not worth doing."
- Second Corollary to WLPC: "If the epiphany never comes, the project will likely be an insanely complex failure."
