AMSAT Engineering Recruiting Volunteers

+ RF Engineer AMSAT is looking for an EE with RF experience to join its FOX-PLUS team. You'll collaborate with an all-volunteer team of up to ten electrical, mechanical, software and systems engineers. You will have the opportunity to design and build the RF communications subsystems for a series of low earth orbit, 1U-3U CubeSats to support AMSAT's educational and engineering objectives.

You should have a working knowledge of analog and digital communications protocols (e.g., FM, PSK, FSK) to provide digitally synthesized audio for FM modulated VHF/UHF/SHF voice and telemetry channels. Development opportunities can begin with modification of previous FOX designs and/or by starting with a blank sheet for an original design.

+ Mechanical Engineers AMSAT is looking for Mechanical Engineers to join its FOX and GOLF CubeSat teams. You'll collaborate with an all-volunteer team of up to 12 electrical, mechanical, software and systems engineers. You will have the opportunity to use your structural design and analysis skills in the development of a series of low earth orbit and highly elliptical orbit, 1U-3U CubeSats to support AMSAT's educational and engineering objectives.

Your contribution may include a) the development of the spaceframe and deployable solar panel subsystem, b) the analysis of the thermal characteristics of the CubeSat and the design of the thermal management system, c) preparation and oversight of the environmental testing procedure, and/or d) management of documentation of the CubeSats adherence to the launch provider's and space vehicle owner's specifications.

Our volunteers typically spend five hours per week on their project and attend a weekly online update meeting. An Amateur Radio license and CubeSat experience is helpful but not necessary. U.S. citizenship or proof of permanent residency is required.

Interested persons should send an email with their resume/curriculum vitae to: [email protected].

NASA Announces Winners of 2022 Annual Space Apps Challenge

The 2022 Annual Space Apps Challenge which was held October 1 and 2, 2022, brought together a host of participants from different locations, cultures, backgrounds, interests, and skill levels. The theme for the 2022 challenge – Make Space – perfectly describes the primary goals of the event: creating innovative solutions to space-related problems, while also making space for people around the world to participate and engage in a collaborative scientific effort.

“NASA’s Space Apps Challenge really puts students around the world to the test, helping to solve some of our time’s toughest problems,” said Bill Nelson, NASA Administrator. “I’m proud of all those who participated and challenged themselves to think creatively. Their remarkable ingenuity is proof that the Artemis Generation will help lead us into the future.” The challenge underscores the importance and value of NASA’s Open-Source Science Initiative that creates more advanced and inclusive research faster, builds a more just and equitable world, and provides access so that great minds from all walks of life can participate in science.

The 10 global winning teams proposed solutions using tools, such as artificial intelligence and machine learning, 3D globes and maps, web applications, interactive games, and the infusion of art and music into their projects. The winning teams were:

- Best Use of Science: What’s New? (Taipei, Taiwan) - Best Use of Data: Starflock (Cleveland, Ohio, USA) - Best Use of Technology: Taming particles (Vilnius, Lithuania) - Galactic Impact: Selene (Jamshedpur, India) - Best Mission Concept: Mars 3D Home (Mendoza, Argentina) - Most Inspirational: Team Diamonds (Cumilla, Bangladesh) - Best Storytelling: MIMBI (Asuncion, Paraguay) - Global Connection: Standard NCTU CS Student (Taoyuan, Taiwan) - Art & Technology: Earth, Wind & Flare (Boston, Massachusetts, USA) - Local Impact: Brute Force (Nisocia, Cyprus)

Satellite Shorts From All Over

+ Newly found is the SARCTRAC Mk3b, a $290 satellite antenna rotator from Australia. USARCTRAC comes with all its components enclosed in a waterproof IP65 rated enclosure. It makes use of a 3D position sensor with magnetometer, allowing the unit to know its orientation at all times, meaning that it should be able to automatically position itself from startup. The design also makes use of DC motors with a built in worm gear drive, so the motors back driving is not possible. The system is controlled via a built in Raspberry Pi 3B+ and can communicate with the controlling PC via WiFi. More information available at https://www.sarcnet.org/sarctrac.html. [ANS thanks rtl-sdr.com for the above information.]

+ The 2022 edition of State-of-the-Art of Small Spacecraft Technology At NASA is now available for download. As with all previous editions of this report, the 2022 edition captures and distills a wealth of new information available on small spacecraft systems from NASA and other publicly available sources. This report should not be considered as a comprehensive overview of all the technologies but a great reference for the current state-of-the-art SmallSat technologies.
