Student and amateur CubeSat news roundup – Sept.3.2019

A sampling of recent articles, press releases, etc. related to student and amateur CubeSat / SmallSat projects and programs (find previous smallsat roundups here):

** Oman university student team builds CubeSat:  SQU team develops sultanate’s first CubeSat – Oman – Muscat Daily

Oman’s first non-commercial CubeSat is a reality now. A team comprising faculty members and students from the Department of Electrical and Computer Engineering of the College of Engineering at Sultan Qaboos University (SQU) has executed the project.

It is a type of miniaturised satellite for space research. The project was proposed and supervised by Dr Amir Mohamed Abdulghani and Sayyid Dr Samir al Busaidi. The students who worked to design the satellite’s payload comprised Abdulaziz Mohammed al Qamshaoui, Luay Khalifa al Yaqoubi and Ali Abdulhamied al Shamali.

** Arizona State University team building Phoenix CubeSat for study of “the Urban Heat Island (UHI) Effect: a phenomenon in which the structure of the city causes a rise in surface temperature”: Mini-spacecraft built by ASU students will study urban heat island effect – ASU Now

If all goes as planned, one day this October a spacecraft the size of jumbo loaf of bread will leave from Wallops, Virginia, packed aboard a cargo rocket bound for the International Space Station.

The spacecraft is a cubesat named Phoenix, and it is the creation of more than 100 science and engineering students, faculty and researchers at Arizona State University.

On Aug. 18, the Phoenix spacecraft was hand-delivered by the student team to Nanoracks, a launch integrator, at their facility in Houston. There it underwent final tests and preparations for its launch to the Space Station, planned for Oct. 21, 2019. After it arrives at the Space Station, Phoenix will be sent into low-Earth orbit sometime early next year.

The Phoenix spacecraft is designed for a two-year mission to take thermal images of several American cities (including its namesake, Phoenix) by day and by night.

** Communications with the Virginia CubeSat Constellation spacecraft built by several Virginia universities and deployed from the ISS into orbit in July have not been established yet: Aerospace team awaits communication with CubeSat after successful deployment into space | The Cavalier Daily

In order to contact Libertas, a “wake-up command” was sent up by U.Va. An acknowledgement packet — a unit of data that must be decoded — was sent back, responding to the ground station signal. Due to technical difficulties with the University’s ground station caused by a series of lightning storms, the Virginia Tech ground station was able to listen in and receive the response signal. By achieving this one-way communication, Libertas is currently the only CubeSat which has responded to a signal, showing that it is alive and working. 

“Initially from deployment, we don’t know if the satellite is on, or whether something broke,” [Uni. Virginia student Connor Segal] said. “You don’t know if maybe the antenna didn’t deploy or the board was hit with a cosmic ray, so the initial step is establishing contact and seeing whether the satellite is alive or not.”

Though the team has not made two-way communication with the satellite, meaning they have not received data, Segal is happy with where the team is at.

Student and amateur CubeSat news roundup – Aug.18.2019

A sampling of recent articles, press releases, etc. related to student and amateur #CubeSat / #SmallSat projects and programs:

** Northwest Nazarene University’s student-built RFTSat was launched into orbit from a Northrop-Grumman Cygnus spacecraft using the SlingShot deployer, developed by the SEOPS division of Hypergiant.

Northwest Nazarene University RFTSat (Radio Frequency Tag Satellite) CubeSat.

RFTSat was deployed into orbit on August 7, 2019!

The NNU RFTSat (Radio Frequency Tag Satellite) CubeSat team is designing and building a 3U CubeSat to demonstrate the application of radio frequency (RF) energy harvesting and backscatter communication to the problem of distributed sensing in space. A small RF tag will be mounted on the side of the satellite and contain a temperature sensor. The tag will not contain a battery, but will be powered by energy emitted from an RF reader inside the satellite. The tag’s sensor data will be wirelessly sent back to the reader via backscatter communication, and then to the Earth via a Globalstar satellite constellation link. RF tags equipped with sensors could be added to a spacecraft, like the ISS, without additional wires or power supplies and provide a means to monitor structural integrity, space weather, or make sensitive electric/magnetic field measurements.

** Student and volunteer Fossa Systems project in Space is building a PocketQube picosat: Spain’s First Open Source Satellite | Hackaday

[Fossa Systems], a non-profit youth association based out of Madrid, is developing an open-source satellite set to launch in October 2019. The FossaSat-1 is sized at 5x5x5 cm, weighs 250g, and will provide free IoT connectivity by communicating LoRa RTTY signals through low-power RF-based LoRa modules. The satellite is powered by 28% efficient gallium arsenide TrisolX triple junction solar cells.

A video from Fossa Systems co-founder Julian Fernandez:

Fossa Systems is a non-profit association based in Spain and dedicated to the development of picosatellite technologies. Our mission is to democratize access to space telecommunications and in-orbit hardware by launching satellites that can fit in your pocket and creating educational and development kits. Our first satellite FossaSat-1 is set to launch in Q3 of 2019 and will create the worlds first free and open source IoT network.
