A. Overview

This project was suggested by Professor Robert Twiggs of Stanford at the 1998 University Space Systems Symposium, JUSTSAP, in Hawaii. ASU students are building soda-can-sized “spacecraft” each weighing about one pound apiece (http://ssdl.stanford.edu/cansat/). Under the pilot effort in Summer 1999, we successfully launched our first set of 3 CanSats from Blackrock, Nevada on September 11, 1999 from an amateur rocket to 11,803 ft (above ground level). With industry providing the requirements, the students successfully received telemetry from these “spacecraft” at their portable ground station. The “satellites” were aloft for 20 minutes. This activity was so successful for all involved that it has developed into a technical-elective course in Mechanical & Aerospace Engineering “Preliminary Mission Analysis and Spacecraft Design” which can be offered every semester. This course takes each student through the complete system development process in one semester. The students aim toward enabling these small systems to be as capable as possible and launching these “satellites” by amateur rocket. In particular, the team works closely with the Arizona High Power Rocketry Association.

One problem inherent with big projects such as ASUSat1 and Three Corner Sat (3Sat) is the length of time from concept through launch and operations. In the case of ASUSat1, this was 6.5 years and in the case of 3Sat, it is looking like at least 5 years. The biggest difficulty with student projects is the high turnover rate of students on the team. People leave at the end of a semester because they graduate, the class is over (if they are working on the project for class credit), or they secure other internship opportunities with industry. Moreover, inexperienced students join the team at different phases and cannot fully appreciate why the project is where it is. IMPORTANT NOTE: The beauty of a project such as CanSat that can be completed within a semester is that a group of students start and end a project together and they experience ALL design phases. The team has concluded that this is a preferred mode both to maximize the undergraduate experience and most effectively use the limited resources usually available for student projects. In the future, ASUSat Lab will likely focus on shorter-term projects such as CanSat and Bob Twiggs’s CubeSat.

B. How to Build

Students from all backgrounds and experience levels are encouraged to participate. In particular, it is desirable to have some knowledgeable electrical engineers, computer scientists, and

mechanical/aerospace engineers working together. A good number of students per CanSat is 6. So if there are 12 people, build 2 CanSats. However, there should be crosstalk, sharing of ideas, and use of common parts wherever possible. The instructor and industry mentors play “customer” and provide a set of requirements and deliverables (see sample Product Definition Requirements - PDR, Appendix 1), and a budget not to exceed $1000 per CanSat. The students play “seller” and organize themselves into the various roles and responsibilities, set up meeting schedules and timelines, prepare and maintain documentation, meet deadlines, and are free to select the experiments. It is the responsibility of the students to interpret the PDR, ask for any deviations, and deliver by the end of the semester. The final grade is based on their performance.

For example, the Spring 2000 class developed three CanSats with a common architecture for structures, electrical, and software. Also employed in the design were considerations and allowances for future expansion. Future CanSats can build upon and use all material produced for this system. The system consisted of: Common structure - A similar all-aluminum structure with a soda-can sleeve was used. Common electronics - All of the electronics boards for the CanSats were the same with

differing components populated on the boards. The boards were student designed and sent out to be manufactured. The same power source of a 9V battery and a UHF transceiver were standard on each “satellite”.

Common software - A common software architecture and packaging scheme were developed for the project. Each can sent its data using identifiers in the data and a variable-length data package was used.

Can1 - DATSat (Dual-Axis Tracking system) - Included two two-axis accelerometers and an electronic compass used to provide a real-time ground track of the can while in the air.

Can2 - EyeCan - Included a temperature sensor, a light sensor, and a black and white analog camera that transmitted cable channel 59, an amateur television frequency.

Can3 - Can o’ SPaM - Included a GPS unit which transmitted latitude, longitude, UTC time, altitude.

Ground station & black box - Consisted of a laptop computer installed with LabView software to run the ground station, a UHF transceiver for communication, and a black box to control the radio and encode and transmit the commands on the uplink and decode and receive the data from the “satellites”.

The mission goals of the project were:

Launch satellites using amateur rockets. Recover satellites using portable tracking equipment. Successfully develop, launch, operate and recover three (3) nano-satellites. Provide results, lessons learned, and reusable hardware for future missions. Operate the satellites using a ground station to collect data according to customer requirements. Develop a CanSat system using course, campus and industry resources and learn the space

system development process.

This project was considered a mission success because it satisfied every one of the mission goals to some extent.

Launch satellites using amateur rockets – One satellite was launched from Flagstaff, AZ on May 5, 2000. The other two satellites were launched from the Blackrock Desert, NV on July 28-29, 2000.

Recover satellites using portable tracking equipment – This was accomplished by downloading data from the CanSats and using that data to find the CanSats. On one can, a GPS receiver was used and that data was used to recover that can.

Successfully develop, launch, operate and recover three (3) nano-satellites – Two of the three satellites were successfully operated from the ground station and recovered, the third was lost.

Provide results, lessons learned, and reusable hardware for future missions – All of the work produced from CanSat2 will be available for use as templates and examples for future projects.

Operate the satellites using a ground station to collect data according to customer requirements – The ground station was setup and successfully communicated with two of the CanSats.

Develop a CanSat system using course, campus and industry resources and learn the space system development process – Future projects, including the current CanSat3 class will build upon and refine the CanSatX system.

The students are encouraged to design and manufacture as much as they can. To this end, tutorials in LabView Solid Works or I-Deas Orcad Electro-Static Discharge (a BIGGIE!) Web Page Development Software Development SPICE Machine Shop Certification Soldering Certificationare some of the first activities. The students work in the same ASUSat Lab as the students building ASUSat1 and Three Corner Sat. Over the years, the program has attained various resources, along with many dedicated industry partners. ASUSat Lab resources developed include high-end workstations capable of detailed finite-element models and complex solid modeling software packages for printed circuit board design, solid modeling, finite-element analysis

class 10,000 clean room fully functional ground station with high-power transmit and receive capabilities on amateur

frequencies knowledgeable team of engineering students with satellite design experience.

Most universities, including ASU, can not provide the full range of resources needed for project success, so industry has helped fill the voids in many areas. Industry is one of the main supporters of the program through, not only through their generous monetary and component donations, but also through their provision of many needed tools. Some examples of tools accessible by the ASUSat team include environmental testing facilities autoclave usage precision machining of composites and other exotic materials rigid and flex PCB and cable harness manufacturing and advisement professionals available for general advisement in all areas (e.g Lockheed Martin, Boeing,

Honeywell, SpectrumAstro, Orbital Sciences, Dynamic Labs) electrical tools such as spectrum analyzers and logic analyzers.

My past nine-plus years mentoring student projects and sixteen-plus years as a professor at ASU suggest the following lessons learned from the instructor’s standpoint: Students thrive in an environment created around a real-world program in which results are

transformed into hardware and then launched or tested. Set high standards and live by them. Promote ethics. Encourage students to take initiative and make decisions. Give students as much responsibility

as is feasible. Encourage students to explore different areas of the project. They should not be confined to

work on a problem that directly correlates with their major, they should be able to explore and grow by learning other subsystems.

Involve as many students as possible in industry-related activities, such as tours, teleconferences, and technical reviews and exchanges.

Spend the extra time teaching a student how to properly do a task. It seems faster as a manager to do it yourself, but if you teach the student properly then he/she can continually perform the task and pass the skill along.

Create and continuously improve a friendly and useful documentation system that makes it as easy as possible on the various team members, and document everything. For CanSat, an electronic Blackboard proves to be a very valuable and friendly tool.

Provide access to state-of-the-art tools. Interact frequently, patiently, and respectfully with students. Listen to their opinions. Mentors

should include faculty, industry, graduate students, and undergraduate peers. Involve students in outreach to local K-12 schools and community and professional

organizations. Promote diversity.

C. How to Use It (including launch methods)

One pleasant surprise realized over the years in working with student projects is that there are many people in the community who want to contribute to and enjoy participating in the experiences of students. It is a matter of getting the word out about the program and identifying those organizations interested in helping out. The ASU CanSat team has especially enjoyed its relationships with the Arizona High Power Rocketry Association (AHPRA), Skydive Phoenix, and AMSAT locally, and ARLISS and AeroPac through the efforts of Bob Twiggs.

With AHPRA, the students can launch up to 3 CanSats at a time on an amateur rocket to 12,000 feet above sea level in West Phoenix, and up to 40,000 feet above sea level in Flagstaff, Arizona. A typical trajectory is shown in the following figure.

Figure 2. Typical trajectory for CanSat launch by amateur rocket

The CanSats are deployed at apogee and parachute back to Earth. Descent time is approximately 20 minutes which is about the same amount of time that one has to communicate with a real satellite passing directly overhead. Students interact with an actual launch provider and the launch and deployment are violent events that the CanSat must survive. In real situations, satellites most often fail because of launch and deployment events – shock and vibration. AHPRA holds a launch event the last Saturday of each month, so there is ample opportunity for testing mock CanSats prior to the “final exam”. The amateur rocketeers are excited to launch payloads. Typically, the CanSat team must build a CanSat carrier to fit within the rocket, buy the motors, and buy the parachutes.

Another avenue for testing has been through a local skydiving group Skydive Phoenix. They have offered to toss CanSats out of aircraft at about 1000 feet.

To communicate with the CanSats during descent, the students build a portable ground station (laptop) and antenna. Students obtain Ham licenses through AMSAT for communication.

Opportunities are readily available around town to obtain a technician-class license.

Every summer, Bob Twiggs arranges an event with ARLISS and AeroPac in Blackrock, Nevada for students from the US and Japan to gather to launch CanSats to 12,000 feet above ground level. This is a terrific opportunity for students to meet their counterparts, share ideas, see a variety of experimental rocket systems, and show school spirit.

D. How to Use It in the Classroom

Spring 2000 saw the first offering of the course “Preliminary Mission Analysis and Spacecraft Design”, aka “CanSat class”. The three-credit course includes the building of soda-can-sized “satellites” with the intent to launch these at the end of the semester on amateur rockets. See the sample Course Description in Appendix 2. Participating in a real space program promotes experience in systems engineering, multidisciplinary teamwork, communication and documentation skills, time and resource management, and industry interaction. For example, for the first offering, Mr. Scott Askins, Ms. Sheila Gover, and Ms. Kate Nelson from Motorola; Mr. Rich Van Riper, Mr. Ron Hundley, and Mr. Brandon Williams from Honeywell; Mr. Rusty Sailors from Lockheed Martin; and Dr. Helen Reed from ASU MAE were mentors. Industry people provide templates for the various documents required and information on the format and content required for the various reviews. The class meets twice a week and it is ideal if the industry people meet with and give the various lectures to the students.

The students organize themselves into a team, determine roles and responsibilities, and determine how to meet the PDR (Appendix 1). The document in Appendix 3 is a sample of how the students can organize to build and launch 3 CanSats. They do trade studies; research various parts and make contact with vendors; maintain contact with the launch provider; prepare and submit paperwork for approval; prepare for the various reviews required; design, build, and test their CanSats; and launch them. To begin with, the instructors assist the students in learning the tools of the trade, e.g. Configuration Management LabView Solid Works or I-Deas Orcad Electro-Static Discharge (a BIGGIE!) Web Page Development Software Development SPICE Machine Shop Certification Soldering CertificationHomework assignments can be prepared to encourage the students to become familiar with these topics. See, for example, in Appendix 4, a sample assignment to do a tutorial on Solid Works.

The course can be organized as follows, although this is by no means set in stone and should be continuously improved based on student feedback.

Preliminary Mission Analysis and Spacecraft DesignFall 2000 Homework 1

Purpose: To learn how to use SolidWorks98 Plus (CAD)

Method: 1. Obtain WEES access card from ETS Helpdesk (located in

Goldwater Rm 181). There is a refundable $10 fee.2. Go to ERC 432. You may or may not need your WEES card, depending

on whether someone is in the lab or not.3. Log-on to one of the two computers nearest the door (both have Hitachi

monitors). Using your ASURITE ID (what you gave Dr. Reed/Candace for computer access), type in a password. Don’t forget your password! Only these two computers have SolidWorks98 Plus software.

4. To begin SolidWorks98 Plus, go to the following path:

This “.pdf” tutorial will guide you through using SolidWorks98.

5. Assignment: Work through the tutorial up to “Mating Parts in an Assembly”. Going beyond this will count as extra credit. Each part/assembly that you create should be saved to your user space. Please follow the “Save” instructions below.

Saving files:1. Since you have your ASURITE ID and your password, you are able to get

into your new “user space” on the ASU Satellite Lab’s server, called RA-PDC.

2. When you have finished creating a file, go to “File”, “Save As…”. In the “Save In” box of the “Save As” window, scroll down to “Users on Ra-pdc”. Double click, and a list of folders, one of them being your ASURITE ID, should show up. Save your file to your folder. Note: You can only get into your folder. No one else can get into yours, unless they have your password.

Due: Tuesday, Sept. 12, 2000. For full credit, bring a printout of all parts/assemblies you have created. If you have gone beyond “Mating Parts in an Assembly”, you may receive extra credit.
