Satellites Engineered by IAE Students, Faculty Launch on World Record Mission

by Russell Nay

Three of the 143 satellites aboard spaceflight company SpaceX鈥檚 first dedicated rideshare mission 鈥� named Transporter-1 鈥� were engineered by students and faculty at the USF Institute of Applied Engineering (IAE).

The mission hosted satellites from dozens of nations and set a world record for the most satellites launched into space on a single mission.

Once in Sun Synchronous Low Earth Orbit (525 km altitude), the satellites built by the 国产短视频IAE team, along with 15 other payloads from more than 10 other organizations, were deployed from global launch services provider Spaceflight Inc.鈥檚 orbital transfer vehicle (OTV) Sherpa-FX1.

Called SmallSats, the miniature class of cubic satellites that 国产短视频students and faculty built have a mass of 1kg (~2.2 lb) and are around the size of a softball. SmallSats have a history of use in low Earth orbit, and the team at 国产短视频IAE aims to use theirs to research inter-satellite networked communications.

国产短视频electrical engineering PhD candidate and IAE Senior Research Engineer Peter Jorgensen said the satellites will communicate both with each other and with IAE headquarters.

鈥淓ffectively, the network is supposed to behave like the Internet here on the ground,鈥� Jorgensen said. 鈥淪omething like that doesn鈥檛 really exist in space right now.鈥�

Ongoing since August 2017, the project to create this network of SmallSats is titled Articulated Reconnaissance and Communications Expedition (ARCE-1). Before finding a home at IAE, it began at the United States Special Operations Command innovation incubator known as SOFWERX, with Jorgensen as program manager, IAE Executive Director of Programs and Customer Engagements Tim Baxter as co-PI and 国产短视频College of Engineering Dean and IAE President and CEO Robert Bishop as principal investigator.

Dean Bishop said the launch on January 24 marked a vital milestone for ARCE-1 and the creation of research opportunities for potentially years to come.

鈥淗aving witnessed this project鈥檚 progress over the last three and a half years through collaborations with multiple university partners, seeing all three ARCE-1 SmallSats enter orbit was a testament to this mission鈥檚 beginnings and its future potential,鈥� he said. 鈥淭his current success is the result of the intellectual and creative talents of the IAE鈥檚 students and staff in tackling tomorrow鈥檚 technological endeavors.鈥�

A notable local partner to the project is the Florida High Tech Corridor Match Grants Research Program, which has multiplied the impact of ARCE-1 sponsor awards across different phases of the project and is focused on research and student engagement.

While full-time staff engineers worked on the project last year, Jorgensen said that the satellites are built and tested primarily by 国产短视频students of various STEM backgrounds employed to join the team.

鈥淪tudents have been at the center of this project,鈥� he said.

Since ARCE-1 began, more than 20 国产短视频students across most engineering majors have worked on the project in some way, with a maximum student team size of almost a dozen at one point. Currently, the team consists of four 国产短视频students who鈥檝e spent the weeks leading up to the January 24 launch completing and testing each of the three satellites.

Catherine Wood, a Fall 2020 国产短视频physics alum, joined ARCE-1 in September 2020 and said she joined near the end of the satellites鈥� physical development during the project鈥檚 testing and deployment integration phases.

Wood said she鈥檚 always wanted to work in the aerospace industry and that getting hands-on engineering skills and experience from this project as part of her current internship with the U.S. Department of Defense has given her a valuable look at a future in the field.

鈥淭his was a perfect and absolutely outstanding experience to have as an undergraduate student and now recent graduate,鈥� she said. 鈥淎 constellation of small cube satellites built primarily by young college students, then being launched by one of the biggest aerospace companies? It鈥檚 a real achievement. It made me feel really proud about what I've been learning and doing at USF, and I鈥檒l carry this experience and what I鈥檝e learned in every aspect of my life.鈥�

David D鈥橝ngelo is a recent graduate from a 国产短视频mechanical engineering master鈥檚 program and joined the IAE team in May 2019. D鈥橝ngelo said that building and testing SmallSats has been an interdisciplinary experience and an opportunity to professionally branch out beyond his field. The rigorous process of ensuring each satellite functioned nearly identically and could withstand a suite of tests and simulations 鈥� from the force and heat of a rocket launch to power consumption while in orbit 鈥� has also made him a more confident engineer.

鈥淲atching our work enter orbit was a great moment to reflect on the culmination of all of our past and present team members鈥� efforts,鈥� D鈥橝ngelo said. 鈥淲e accomplished something that takes a lot of time and dedication, and seeing that realized was special.鈥�

Also having joined ARCE-1 in May 2019, mechanical engineering graduate student Troy Young said his time at IAE settled his path after graduation and convinced him to switch his master鈥檚 thesis focus from mechanical engineering-related research to research in spacecraft guidance navigation and control. Over time, his work on the project evolved from mechanical engineering-based tasks like fabrication and simulations to tasks of various engineering disciplines.

鈥淭his project has been about challenging ourselves and branching out into subjects we鈥檝e never thought about or didn鈥檛 know existed sometimes,鈥� Young said. 鈥淵ou鈥檙e thrown right into the chaos of designing and producing something that needs to work and be a part of a system going into space. It鈥檚 been one of the most effective ways I could imagine getting trained as an engineering student.鈥�

With all three SmallSats in orbit, Jorgensen said the team鈥檚 next task is to complete an orbital analysis of the satellites鈥� path around the Earth and use the next several weeks to prepare for the project鈥檚 next research phase. Then, they can push software updates to the satellites to expand their functionality.

While this initially includes the ability for each SmallSat to autonomously sense how far it is from a message target 鈥� maximizing messaging efficiency 鈥� the network could one day provide mobile communication services to locations almost anywhere on the globe.

鈥淭he intent would be to expand communications capabilities to less connected areas of the Earth,鈥� Jorgensen said. 鈥淔or example, if a major disaster happened that wiped out all cell networks and all Internet in a large area, these satellites could theoretically be used for communications from that area.鈥�

Jorgensen said the capabilities of 国产短视频IAE鈥檚 network will depend on how much support ARCE-1 receives over the years and the overall lifetime of the project.
