Avionics Home Page

The Avionics team is currently working on 'AV3' class hardware and firmware for the Launch Vehicle No. 2c airframe. The AV3 hardware is run by an Intel Atom-based PCI-104 flight computer (FC) attached to various sensor and actuator nodes using Ethernet as a low-latency safety critical bus and USB as an easy bulk-data bus. The sensors and actuators include a GPS, IMU, power system, and amateur TV broadcast.
