EQUiSat to launch into space May 9
NASA-funded student group constructs satellite, hopes to inspire interest in space among youth.
Since its conception nearly seven years ago, a continuously revolving group of University undergraduates has been diligently working to send a satellite into space. Now, as May 9 draws closer, the group of over 200 past and current students and faculty can find catharsis as the EQUiSat will finally launch into orbit.
The project, funded by NASA’s CubeSat Launch Initiative, will send a small cube satellite to the International Space Station to then launch into orbit. The EQUiSat will test lithium iron phosphate batteries, which are used in machines such as lawn mowers, but find limited applications in spacecrafts. Due to its low cost and the fact that its latitude will coincide with that of Providence, which allows its LED flashes to be seen from the ground, the satellite will also serve as a symbol for the accessibility of space.
“A big part of the goal is proving the accessibility of space. … We kind of want to show people that space is right there,” said Hunter Ray ’18, the project’s co-leader and team manager. The project could have cost upwards of tens of thousands of dollars, but the team has kept its cost to just $3,776.61, Ray added. The project’s relatively low cost and mantra to “build it from the ground up” speak to the feasibility and accessibility of space.
The EQUiSat will be equipped with powerful LED lights, a small radio and multiple sensors to keep track of its trajectory and control steering. “Anyone with a hand radio can pick up its frequency. … We will be relying on the community of amateur radio (groups) around the world to help collect EQUiSat’s data,” Ray said. He described the construction process as his favorite part of the project. “It’s like a Lego set. You build it and you’re like ‘great, now what do I do,’ … but the mission will keep going.”
Ray has been a part of the project since he arrived on campus. “I started freshman year, first week … (I decided that) I want to build a spacecraft,” he said. “I ended up taking over for the power system development, … (and then) I was elected as part of the project’s manager and co-leader of the team,” he added. He hopes to see similar projections come together in the future following the EQUiSat’s launch. “The fact that as undergraduates we have been able to build an entire spacecraft from scratch … (it shows where) we are going with the space program, as humanity is progressing into the final frontier,” he said. Ray will be delivering the EQUiSat to Houston this week in order to facilitate preparations for the launch.
Anand Lalwani ’18 leads the power team, the group of 17 team members in charge of the EQUiSat’s solar power and battery construction. “We are a group of incredibly motivated, but incredibly fun people. Yes, we have had our arguments and fights, but we still work very well with each other,” he said. The power team not only constructed solar panels from scratch, but also ensured that they would survive a launch. Eventually finding a coating and the means to apply it to protect the delicate panels was a grueling process, Lalwani said. “We tried (different protocols) for about 12 months, … and we failed consistently,” he said. Finding a solution “was probably (Brown Space Engineering’s) biggest achievement,” as no other satellite group in the country had done this, he said.
The project also serves as an outreach symbol, Lalwani said. By talking to both middle school and high school students and teaching them about different aspects of engineering, the team hopes to show children that space is not as far-fetched as it may seem. “What we had pitched to NASA in our original mission was that ‘We are going to make space cool again,’” Lalwani said. He hopes to see BSE continue its work with new satellites being constructed in under two years.
“For BSE, our future is very bright. … All our future applications for launches such as this will be very likely granted. … We expect all the sophomores in our team to have a satellite they would have designed and built and launched before they graduate from Brown,” he added.
Max Monn GS, one of founders of the initial project, worked on the project from its initial creation in 2011 to 2013. “Since the manned space missions to the moon … (the public) had a declining interest for space” due to the lack of human connection, Monn said. The origin for the project began as a means for creating an idea in Adjunct Associate Professor of Engineering Rick Fleeter’s class, which has since evolved into ENGN1760: “Design of Space Systems,” Monn described. While other projects leaned toward theoretical concepts or plans such as the colonization of Mars, Monn and the other founders decided to plan something which was “down to Earth” and did not need a large corporation to complete, Monn said.
The EQUiSat’s LED lights flashing down toward Earth show the accessibility of space, one of the project’s main purposes. This element was inspired by Monn’s interest in photography. Following the initial work, the project expanded from a four-person class project to a student group. “We weren’t really sure how it would be received,” he said. At the first information session, 15 to 20 people showed up. Seeing the growth of the group has been one of Monn’s favorite memories of the project. “It feels like a legacy,” he said.
Serving as founder, member and mentor, Monn has seen the project evolve from “wires spread out on a table” to its eventual launch. “We had these visions of what it could be and to have left the project in such shambles … (and) having it become more and more real… (it’s) a pleasant surprise,” he said.
“You don’t need to be a multi-millionaire, you do not have to be a rocket scientist, and space is not that far,” Lalwani said. The satellite will serve as a realization that the final frontier is truly not as far as it seems, he added. “EQUiSat is reaching down to everyone on the Earth and showing them that space is right there, and I hope that, in a sense, it helps unite everyone together,” Ray said.

Pearl Technology STEM Camp, June 18-22, 2018 in Illinois
The STEM Academy is sponsored and put on by Pearl Technology, with the assistance of the University of Illinois Extension, Richwoods Township, Goodwill Industries of Central Illinois, Peoria Area Ama- teur Radio Club, Peoria Heights High School, volunteer Caterpillar engineers, and ISS Above Software.
Twenty-five middle school students will spend June 18-22 attending the STEM Academy held at Goodwill Commons, where they will learn about space and radio communications. The students will build Rasp- berry Pi computers that stream live video from the ISS. Students will also participate in a high-altitude balloon launch by building the payload with student experiments and then, use radio telemetry to track the balloon to near-space.
The highlight of the academy will be when students communicate directly with astronauts on the International Space Station. The ISS contact will be open to students of all ages in the local area.

Introducing CATSync - The new CAT tool for WebSDRs
Oscar, DJ0MY, has developed a new software tool for radio amateurs and SWLs.
CATSync allows the user to control public WebSDR receivers with a real rig connected via CAT. It supports the classical Web-SDR servers as well as the newer Kiwi SDR servers publically available on the internet.
This gives you access to dozens of web based receivers with the comfort of tuning your rig at home. This software helps you to bring you back into the fun of ham radio when you are suffering from local temporary or permanent high noise levels in an urban QTH location.
The software has the following features: - Syncronizes any public WebSDR server with your real RIG… - Supports a wide number of RIG’s (it uses the popular OmniRig engine) - Supports WebSDR and KiwiSDR browser based SDR receivers - Tune the VFO of your radio and see the web SDR follow in realtime! - Switch modes (SSB, CW, etc.) on your radio and see the web SDR switch mode in realtime. - Listen to the same frequency as your rig via web SDR - Ideally suited e.g. for people suffering from local QRM - Can track RX or TX VFO (e.g. to find that split of a DX station) if radio CAT supports both simultanously - Can be interfaced with popular logging software using OminRig or via VSPE port splitter

+ AO-91 Distance Record
The footprint on AO-91 has been stretched yet again to 6,123 km with a QSO between @eb1ao and PU8MRS on 17-Mar-2018 at 14:51 UTC. https://www.amsat.org/satellite-distance-records/ .
+ PicSat Goes Silent
PicSat @IamPicSat Tweeted: I am feeling somewhat confused up here. My communication has fallen silent (sorry faithful listeners, I did not see that coming. My team is trying to find out what happened. More to follow, when I pass over Paris @amsatf #amsat @AmsatUK @amsat_sm @SatNOGS
PicSat @IamPicSat Tweeted: Passed over Paris, couldn't not talk. Don't know why, neither does my team. They tried! Fortunately, I have a so-called watch-dog onboard, a piece of hardware that will kickstart me if I have not received anything from nobody for 72h
PicSat team tweeted Friday morning: Nothing, nix. I still cannot communicate. Hard for me to tell if my Watch Dog initiated the kick start. If it did, and it did not work for some reason, it will try again in 72h from now. In the mean time, pls stay tuned!
Monday March 26 will be the next time the 72 hour watchdog fires.
