-**Portland State Aerospace Society** (PSAS) is an educational aerospace project at [Portland State University](http://pdx.edu/) in [Portland, Oregon](http://en.wikipedia.org/wiki/Portland,_Oregon). We are a team of students, alumni, and local community members who have a love for learning through difficult, hands-on, cross-disciplinary engineering projects. Over the last decade we have been designing and building world class experimental rockets.
+Our long term goal at Portland State Aerospace Society is to put a *tiny satellite into orbit*. This is very ambitious--there are so many technical, financial, and legal challenges that we may never never get there! However, this goal clarifies our intent and allows us to ask, "Where do we start?"
-We are dedicated to an open approach to engineering &mdash; sharing what we learn with the larger educational and amateur rocket community.
+The answer is that we focus on small, ongoing projects which move us toward our long-term goal. We build everything ourselves from the ground up and our work necessarily touches all aspects of aerospace engineering. Our rockets are in the amateur classification: smaller than commercial but larger than model rockets. We haven't built the biggest or highest-altitude amateur rocket, but we hope we're building one of the most sophisticated.

-## Our Goals
+Outreach is an important part of what we do as an educational project. We've done many presentions at local schools, and all our projects are open source &mdash;from CAD drawings to schematic diagrams to our software.

-Our long term goal is to put a *tiny satellite into orbit*. We know just haw hard a problem that is! There are many technical, logistical, financial, and legal issues to work through. We may never never get there, but having this goal allows us to ask the question: &ldquo;what's the first step in the process?&rdquo;
+[[!toc levels=3]]
-We focus on small, ongoing projects that move us toward our long-term goal. These projects involve all aspects of aerospace engineering, from soft-ware and embedded systems development to electrical and mechanical engineering. We do everything ourselves, from simulation and data analysis to controls engineering and communication system design.
+## Get Involved!
-The rockets we build fall into the class of &ldquo;amateur rocketry&rdquo; &mdash; smaller than commercial rockets, larger than model rockets. We certainly haven't built the biggest or highest altitude amateur rocket, but we do hope that we're building one of the most sophisticated.
+We're looking for anyone who is interested in rocketry or engineering. There are thousands of problems to tackle so [[contact us|Contacts]] or drop in on [[a meeting|Schedule]] and we'll introduce you to the project and let you decide where you want to fit in. Here's a quick blurb for [[new members|NewMembers]].

## Areas of Work
### Avionics
-Avionics are the computer &ldquo;brains&rdquo; of the rocket. We're trying to be one of the first amateur groups in the world to make an actively guided rocket&mdash;<em>i.e.</em>, a rocket that is autonomously guided by an on-board computer.

LV2 is our current generation vehicle. It has a modular design and a robust, redundant, dual deploy system and lots of room for electronics. We have launched this airframe several times. Unfortunately our [[2005 launch resulted in a complete loss of the vehicle|news/2005-08-20]]. Since then we have rebuilt the airframe with a few upgrades and [[resumed flying in 2009|news/2009-05-31/]]. We continue to innovate, adding a [[roll control|rollcontrol]] module for our [[flight in June 2010|LV2c_LaunchData-2010-06-27]]. We will hopefully re-integrate our earlier full avionics stack and then move on to bigger, lighter airframes and a yet more advanced flight computer before 2011.

-We also try and reach out to the community as much as possible. We're a regular attendee at [[OMSI&#39;s Space Days|/news/1999-07-18]], we've done many educational presentations to local middle and high schools, and we're strong advocates of cross-discipline engineering projects at Portland State.

-## What are your current projects?
-
-We are still working with LV2. We have successfully launched and the airframe as a hardware test (in addition to several previous launches of the same design). Each subsequent launch includes a new piece to test as we push the envelope of "amateur" rocket systems. LV2 project variants include active roll control and spin-can flights. We are now starting to think larger and more complex; with projects involving staging and guidance in the works.

-We're currently working on the next generation vehicle, called [[Launch Vehicle No. 2|ProjectLV2]] (LV2). The modular airframe and recovery systems were first launched in [[2002|news/2002-09-22]]. When all subsystems are complete it will have a projected altitude of 21km (70,000ft), an advanced avionics system which will be the basis for our active guidance system, a modular airframe system, and perhaps most importantly, build on everything we&#39;ve learned from the last three rockets. LV2 is partially funded from a $10,000 grant from the NASA Space Grant Program. A [[Usenix2003Paper]] giving an overview of the project and focusing on the software of the avionics system will be presented at <a href="http://www.usenix.org/events/usenix03" target="_top">USENIX 2003</a>.

-We've also been working on paraffin-oxygen hybrid rocket motor technology and have a lab-scale rocket motor which is helping direct the design of a full-scale motor.

-## Are you sharing all of these developments?
-
-You bet. All projects we do are open source, from our CAD drawings to schematic diagrams to our software. We pride ourselves in sharing what we learn with the world of amateur rocket enthusiasts, and with our ability to collaborate with other groups.

-Absolutely! We need the help! We're looking for anyone who is interested in rocketry or engineering. There are thousands of problems to tackle, ranging from stoachastic control theory to airframe design to computer programming to logistics support. [[Contact us|Contacts]], or drop in on [[a meeting|Schedule]], and we'll introduce you to the project and let you decide where you want to fit in! Here's a quick blurb for [[NewMembers]].

-## Do you have more information available?
-
-This site contains all of the information we have on our project. We do have printed materials available for donors, press, and potential payload developers; please [[Contact us|Contacts]] if you're interested.
