Title
An Open Standards Approach to a Complete Launch Vehicle Avionics System
Abstract
In the larger field of avionics, network-centric environments are commonly comprised of networks that connect either widely dispersed nodes, such as in air traffic control, or local point-to-point connections, such as within a vehicle's avionics system. In this paper, we show how an entire avionics system, from flight control to ground support, can be inexpensively and rapidly built using open standards.
The Portland State Aerospace Society (PSAS) is an educational aerospace engineering project at Portland State University that develops small, inexpensive sub-orbital launch vehicles with avionics systems based on open source software and commercial off-the-shelf (COTS) hardware. To reduce cost, development and construction time, PSAS uses application appropriate networking. This includes IEEE 802.11b for long distance telemetry, Ethernet for vehicle diagnostics, and both USB and CAN for intra-vehicle networks. We describe how open standards networking can be pushed to fulfill application appropriate requirements.
