Launched July 4th in partnership with the University of Arizona, the mission, led by Principal Investigator Dr. Walker and FreeFall Senior Engineer Dr. Aman Chandra, is a technological and educational demonstration. It comprises multiple FreeFall-designed antennas, each addressing unique mission needs.</h2>

<p>“The first, an <strong>inflatable X-band spherical antenna</strong>, enables rapid data downlink while demonstrating advanced inflatable antenna technology. The highlighted technology of the CatSat mission—This Mylar antenna, compactly stowed for launch, unfolds in orbit to provide a large, high-gain aperture that dramatically enhances data return.</p>
<p>The second is a <strong>patch antenna solution</strong>. We have two of these patch antennas onboard the spacecraft. One was designed for the X-band to serve as the backup downlink solution, and the other was intended for the C-band to act as a radio beacon to be detected by ham radio operators worldwide.</p>
<p>The third antenna developed by FreeFall is the <strong>HF whip antenna</strong> for the WSPR experiment, which utilizes amateur radio stations worldwide to study the conditions of the ionosphere and accomplish the mission’s pedagogical aspects.”</p>

<p id="caption-attachment-24041" class="wp-caption-text">FreeFall Aerospace’s 10GHz Patch Antenna</p>
</div>
<p>For the <strong>patch antenna,</strong> the challenge was developing a solution that produced circular polarization to maximize the spacecraft’s downlink capability regardless of how it was oriented with respect to the 6.1m ground stations dedicated to picking up X-band signals from CatSat. From a design standpoint, most work focused on optimizing the interactions between the internal structure inside the patch and external features designed to produce circular polarization. Again, the ANSYS software greatly aided in this design work.</p>
<p>The <strong>HF whip antenna</strong> had to be designed to cover all the bands that ham radio operators utilized with the WSPR protocol and network. Therefore, its length was critical for correct operation, and we utilized established amateur radio rules of thumb and engineering practices to complete the design work. Also, the design process involved constant communication between the RF and mechanical teams to account for the deployment’s electrical and mechanical aspects to minimize risk and unexpected outcomes.</p>
<p>In addition, FreeFall designed the physical structure of the HF whip antenna and deployer. At the same time, <a href="https://www.rincon.com/">Rincon Research</a> was responsible for developing the HF upconverter electronics to optimize the throughput and X-band downlink of WSPR data for post-processing and scientific dissemination of the WSPR ionosphere experimental results. Their contribution was crucial to the success of the CatSat mission.</p>
<h2 class="fusion-responsive-typography-calculated" data-fontsize="18" data-lineheight="27px"><strong><em>What testing phases were critical to ensure each antenna would perform reliably in orbit?</em></strong></h2>
<p>The most crucial test phases for validating the antennas to work in orbit are thermal-vac, vibe, and shock. These rigorous tests ensure the resilience and reliability of the antennas in the harsh conditions of space, providing reassurance to all stakeholders.</p>
<h2 class="fusion-responsive-typography-calculated" data-fontsize="18" data-lineheight="27px"><strong>CatSat Continues:</strong></h2>
<p>Operating in low-Earth orbit, CatSat orbits Earth 15 times daily, relaying high-definition imagery and conducting ionospheric studies. The mission, led by Principal Investigator Dr. Walker and FreeFall Senior Engineer Dr. Aman Chandra, is not just a technological feat but also an inspiring educational demonstration that we can all support.</p>

<p><span style="font-weight: 400;">CatSat is a 6U CubeSat built by GOMspace of Denmark that is now being integrated and tested by UA students from various departments, including Aerospace and Mechanical Engineering, Astronomy, Computer Science, and Electrical and Computer Engineering. It allows undergraduate and graduate students to get hands-on experience developing and operating a space mission and involves dozens of UA students across campus.</span></p>
<p><span style="font-weight: 400;">Once in orbit, the FreeFall antenna will deploy using compressed gas to inflate a 0.5-meter diameter Mylar spherical reflector incorporating a proprietary feed system.&nbsp;&nbsp;Through the inflatable antenna, CatSat will transmit high-definition Earth imagery in real-time to a 6.1 m ground station antenna at <a href="https://techparks.arizona.edu/">Tech Parks Arizona</a>. A second “whip” antenna will also be used to probe how Earth’s ionosphere structure varies at different times of the day. CatSat will orbit Earth approximately 15 times a day during its expected 6-month lifetime.</span></p>
<blockquote>
<p><em>“Qualifying our inflatable antenna is a crucial step for FreeFall Aerospace, the University of Arizona, and Tucson’s developing space ecosystem. We’re looking forward to making this capability available for commercial, scientific, and government space missions.”</em></p>

This approach will dramatically increase the total data return and overall effectiveness of Cubesats and other small satellites.</p>
<p>During the CatSat mission, the FreeFall inflatable antenna will transmit high-definition Earth imagery to a 6.1 m ground station antenna located at Biosphere2 near Tucson. A second whip antenna will also be used to probe how the ionosphere structure varies at different times of the day. The 6-month CatSat mission will complete the testing and validation of the FreeFall inflatable antenna and will&nbsp;represent a major contribution to&nbsp;future commercial, scientific, and government space missions.</p>								</div>

<h2>ANSYS Video Transcript</h2>
<p>Data is the lifeblood of modern society. But more than half of the world’s population doesn’t have access to the internet.</p>
<p>Our reliance on continuous connectivity will grow and form the basis of technologies like 5G and 6G. All of this relies on the ability to efficiently move large amounts of data, and more of that data must move to and from space.</p>
<p>And there is a revolution in the making.</p>
<p>Freefall Aerospace is developing revolutionary new antenna technology for ground, air, and space. We make unique and highly efficient antennas for small spacecraft and ground stations, which together enable <a href="https://www.freefallaerospace.com/spacecraft/">big data from CubeSats</a> and other small, low-cost spacecraft to provide continuous global coverage.</p>
<p>This innovative antenna system uses spherical reflectors and beam steering to provide complete coverage and enable a dramatic increase in data rate with minimum mass, power, and complexity, which is critical to the space-based communication systems of the 5G world and beyond.</p>
<p>Our team had to overcome a number of challenges, not the least of which were the limitations in high-fidelity simulation software.</p>
<p>“One of the most difficult things to overcome in EM simulations is the meshing of structures. You can think of a mesh as a faceted representation of the antenna or device you are trying to model. The meshing allows us to solve Maxwell’s equations numerically and arrive at solutions representative of how the device behaves in the real world from an RF perspective.</p>
<p>In the past, when we were using a competing software solution, I would need to manually specify characteristics of the mesh to get it just right to model an antenna with sufficient accuracy, which can become very difficult with increasingly complex models of different size scales.”</p>
<p><a href="https://www.padtinc.com/">Phoenix Analysis &amp; Design Technologies</a> (PADT) introduced us to the Ansys Startup Program and showed how to use <a href="https://www.ansys.com/products/electronics/ansys-hfss">Ansys HFSS</a>, a 3D electromagnetic simulation software, to solve our problems.</p>
<p>Because of the speed of Ansys HFSS and its ability to solve multiple simulation challenges in different domains, we were able to analyze performance and make design changes more quickly and with better data.</p>
<p>“HFSS automated our process of determining the proper mesh, and that has decreased preparation time and increased accuracy of results for a given amount of time. We also think that HFSS is much easier to navigate in instances where you have more granular control over the simulation process.</p>
<p>We built complete models in HFSS, which allows us to move directly into the prototyping stage with confidence. Meeting our customer requirements with accuracy and speed is our priority, and Ansys HFSS makes that possible. These tools and the support from Ansys and PADT have been invaluable. “</p>

<p>Together they have enabled us to expedite the development process and create a more valuable product.</p>
<p>Undoubtedly, using and relying on HFSS has provided us with an immense increase in efficiency and is accelerating our time to market.</p>

										<content:encoded><![CDATA[<h1>FreeFall Aerospace’s Phased Array: An Antenna Like No Other</h1>
<h2>Gottleib&#8217;s Satellite Mobility World | Feb 2021</h2>
<p class="p1"><em>The quest to develop a low-cost electronically steerable antenna (ESA) has been an elusive one. Despite hundreds of millions of dollars invested by over a dozen companies, a viable, low-cost antenna has yet to emerge. For years, satellite industry engineers have battled the laws of physics, power consumption, heat, and cost in their struggle to build the ultimate antenna. They have employed PCBs impregnated with thousands of chips, and metamaterial designs &#8211; all resulting in high-cost solutions. We at Satellite Mobility World are pleased to present a unique and simple solution to the challenge, the FreeFall Aerospace spherical antenna. To find out more about this unusual antenna, we met with CEO, Doug Stetson.</em></p>
<p class="p1"><b><i>SMW: Can you tell us about the origins of FreeFall Aerospace? </i></b></p>
<figure id="attachment_12528" aria-describedby="caption-attachment-12528" style="width: 150px" class="wp-caption alignleft"><img loading="lazy" decoding="async" class="size-full wp-image-12528" src="https://www.freefallaerospace.com/wp-content/uploads/2020/07/DougStetson_FreeFallAerospace_150.jpg" alt="Doug Stetson FreeFall Aerospace" width="150" height="200" /><figcaption id="caption-attachment-12528" class="wp-caption-text">Doug Stetson, CEO of FreeFall Aerospace</figcaption></figure>
<p class="p1"><strong>Doug Stetson:</strong> Tucson, Arizona based FreeFall Aerospace and its antenna are the products of Space exploration programs. The inventor of our unique technology, Dr.Chris Walker, is a Radio Astronomer. My background is an expansive career at the Jet Propulsion Laboratory, working on such bold Space exploratory programs as Cassini, Galileo, and Mars exploration. We can find the origins of the FreeFall antenna in derivations of Chris Walker&#8217;s signal detector technology. Although developed for Radio Astronomy, we realized that it had enormous potential when applied to satellite communication. So, in late 2016 we incorporated FreeFall to develop and commercialize the technology.</p>
<p class="p1"><b><i>SMW: FreeFall&#8217;s antenna incorporates a spherical rather than parabolic reflector &#8211; a design rarely seen in the satellite industry. What advantages does it have over conventional parabolic and phased arrays?</i></b></p>
<p class="p1"><strong>Doug Stetson:</strong> Most high-gain satellite antennas are parabolic dishes or flat panel phased arrays. Instead, the FreeFall antenna uses a spherical reflecting surface. Unlike a parabolic antenna, which has a very narrow field of view and must be precisely pointed to achieve high-gain, a spherical reflector has the widest possible field of view, dramatically simplifying the acquisition and tracking of a satellite or ground station. A characteristic of a spherical reflector is that it focuses energy on a focal line rather than a focal point as in a parabolic antenna. The <a href="https://en.wikipedia.org/wiki/Arecibo_Observatory" target="_blank" rel="noopener">Arecibo Radio Telescope</a> is the prime example, and in that case, beam steering was accomplished by physically moving the feed along a semi-circular track. That said complex mechanical process, and if you can avoid it, there&#8217;s a tremendous saving in mass, power, and operational complexity for both Space-borne and ground-based antennas. That&#8217;s innovation.</p>
<p class="p1">Instead of physically moving the line feed, we do it electronically. We have developed a phased array line feed that allows us to provide wide-area coverage at high-gain without requiring any physical motion of the antenna and without moving parts. Our <a href="https://www.freefallaerospace.com/ground-station/" target="_blank" rel="noopener">All-Sky<span class="s1"> </span>antenna</a> offers the beam-steering capability of a flat panel phased array, the high-gain of a parabolic dish, without the complexity, high power, and high cost of an electronically steered flat panel phased array. The antenna has all the advantages of an ESA except for flatness, and it&#8217;s simple to build and inexpensive to manufacture.</p>

									<p><span style="font-style: inherit; font-weight: inherit;">An Interview with Doug Stetson, President of FreeFall Aerospace:</span></p>
<h2><strong>Where did you grow up?</strong></h2>
<p>&#8220;My Dad was in the Air Force so we moved around a bit, but mostly I grew up in Southern California. We spent a few years at Edwards Air Force Base when I was little so I got to see a lot of flight tests of cool planes back in the 1960’s. I think that’s what got me hooked on aerospace. I followed through with that in college at Stanford University.&nbsp; I also earned a degree in Physics and then a Master’s in Aeronautics and Astronautics. We lived near Disneyland so I worked there during a few summers when I was home from college. I drove the Jungle Cruise boat so I could tell dumb jokes and shoot at the hippo.&#8221;</p>
<h2><strong>What was your previous work experience?</strong></h2>
<p>&#8220;My first real job was at JPL starting in 1983 doing mission design, orbital mechanics, and spacecraft systems engineering for future solar system exploration missions. After a while I went to Washington DC for a few years as manager of advanced studies for the planetary program. When I returned to JPL I took on a number of program management roles, the last one being manager of the Solar System Exploration Program Office which focused on mission development, strategic planning, and new technologies for planetary exploration.&#8221;</p>
<p><strong style="font-family: &quot;Work Sans&quot;, sans-serif; font-size: 2.5rem; font-style: inherit;">What were some of the cool projects you worked during your 25+ years at JPL?</strong></p>
<p>&#8220;Most of the missions I worked on never actually flew, which is just the way it is in space science – you develop investigations and projects and propose them up the chain at NASA, and ultimately they make a selection based on science priorities, risk, and budget. But we always learned a lot by designing new missions and they frequently led to new technologies that would eventually get developed. I spent a lot of time on the Cassini mission to Saturn, which was launched in 1997 and just completed its mission last year. My primary role was the initial design of the orbital tour of the Saturnian system with flybys of the various moons, and that was a great job and very satisfying to see it actually take place.</p>
<p>Over the years I worked on concepts for missions to all of the planets as well as comets and asteroids, including the Galileo mission to Jupiter some of the early Mars orbiters and rovers. I kept on with some of that work as a consultant after I left JPL.&nbsp; We just finished a proposal to send a drone to explore Titan, which is the largest moon of Saturn. It’s one of two finalists in the latest competition for major NASA missions, and if that’s selected it will be the coolest one ever!&#8221;</p>
<p><strong style="font-family: &quot;Work Sans&quot;, sans-serif; font-size: 2.5rem; font-style: inherit;">What is FreeFall and how was it started?</strong></p>
<p>We like to say that our business is “moving data”, and of course these days there is a huge amount of data to move every day. And the vast majority of that data moves through antennas at one point or another, so in a nutshell we’re an antenna company. As part of my consulting business I had started working with Chris Walker, who is a professor of astronomy at University of Arizona. Chris had developed the concept of <a href="https://freefallmovingdata.com/spacecraft/">highly efficient spherical reflectors</a> for his research projects, and he realized that this technology could greatly improve the data return capability of small spacecraft. I had just finished working on the LightSail project that deployed a solar sail from a small spacecraft, so I was interested in the challenges as well as the potential of this technique. So one weekend I got on LegalZoom and formed an LLC and we were off and running. Since then we’ve grown a lot and morphed into advanced antenna technology for not only satellites, but also ground stations and <a href="https://freefallmovingdata.com/5g/">5G internet wireless applications</a>. I still have a picture of the whiteboard on which we roughed out the first ideas for the company in August 2016, and we really had no idea where that would lead.</p>
<h2><strong>What’s been challenging, and what are some of the key accomplishments so far?</strong></h2><div><strong><br></strong></div>
<p><em><strong>What hasn’t been challenging?</strong></em> There’s a whole bunch of things that I either didn’t anticipate, or at least didn’t appreciate how significant they would be. There’s intellectual property, which we’re fortunate to have but brings a lot of complexity and expense. There’s finding office space and equipment, which of course you need but that’s not cheap either. There’s finding the right employees, which is absolutely critical but not easy. The list goes on and on and it seems like there’s something new every day. But even so I’d say we’ve had a lot of success so far. Most of the potential customers we’re spoken to seem to be excited about our technology and understand that there are huge benefits to moving more data better, faster, and cheaper, which is what we’re trying to do. We’re building our prototypes that will demonstrate these new techniques and they should be ready for full-scale demonstration in just a few months. And we’ve got a great group of people who are totally committed to what we’re doing and really enjoy working together, and for me that’s what makes it all worthwhile. Yes it’s a challenge, but I’ve learned a lot and it’s fun coming to work every day.</p>
<h2><strong>Any other advice you would give entrepreneurs?</strong></h2><div><strong><br></strong></div>
<p>Don’t try to do everything yourself. There’s just too much and you’ll go crazy and then you’ll go nowhere. Concentrate on finding the right small team and trust those people to do their jobs, so you can focus on setting the vision and guiding the company, finding customers, and raising money. Without those three things you’re finished before you start. And don’t become what I call a “self-licking ice cream cone”, which is a company that’s in business just to stay in business. Be sure you’re solving an actual problem and providing real value to your customers, and have a plan for growth and development of your business and your team. That’s what will make it satisfying and successful in the long run.</p>

<div class="entry-content">
<p>As a nation, we’ve been through spells of obsession with the idea of heading into space and exploring the final frontier. And with movies like&nbsp;<i>First Man</i>&nbsp;and genius/Bond villains like Elon Musk planning to shoot themselves into space for whatever reason, space is cool again. But one place where the cosmos has never been in flux as far as interest is the University of Arizona, a place where space industry startups are popping up, like Freefall Aerospace.</p>
<p>The UofA technology spinoff started orbiting the space tech sphere in the fall of 2016 with a focus on developing a prototype of its spherical antenna. The antenna’s reflector design gives a 360-degree field of view for reception and can be maneuvered electronically to track signals through intricate algorithms from a computer.</p>
<p>The main goal for the people at Freefall Aerospace, including UofA astronomy professor Chris Walker and NASA veteran Doug Stetson, was to deviate from how typical shallow-dished parabolic antennas operate. Those antennas can only focus on a single point and have to be physically pointed in the direction of a signal. So, creating a handy antenna that’s operated like a remote control is in charge expands the possibilities of the data it receives.</p>
<p>Freefall Aerospace just teamed up with NASA and stuck its antenna on the space agency’s biggest research balloon.</p>
<blockquote>
<p>“We can provide high gain communications over virtually the entire sky with a single antenna system, without the need to physically point the antenna – it is all done electronically,” says Stetson. “This is a major simplification and will reduce the mass, power, complexity, and cost of communication antennas in space and on the ground.”</p>
</blockquote>
<p>The test ride took place in August, but it was successful enough to push the company forward with more research and the ability to expand the antenna technology. The flight test included other experiments on the 60-million-cubic-foot balloon at 159,000 feet of altitude.</p>
<p>The interesting thing about the Freefall antenna is that it strengthens the signals it’s trying to reach by being able to point at various destinations over the course of a flight. A regular parabolic antenna loses signal strength because it must be pointed at one spot. Freefall’s antennas also sport the ability to handle high data-transfer rates (think the wondrous 5G network we’ve all been hearing about), and are relatively cheap to manufacture.</p>
<p>The successful test flight positioned Freefall as a leading startup in its development of this kind of technology. The company is also working on making antennas for ground stations and ships. The antenna aboard the NASA balloon gathered eight hours worth of data.</p>
<blockquote>
<p>“The main advantage of our approach is that we provide a very wide field of view with high data rates, and the antenna beam can be electronically steered so there are no moving parts,” adds Stetson.</p>
