Student and amateur CubeSat news roundup – June.2.2019

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

[ Update: A satellite developed by China’s AMSAT group and the Beijing Institute of Technology ( BIT ) is set to launch this month on a Chinese commercial rocket:

From ARRL:

… the CAS-7B satellite, also designated as BP-1B, a short-lived spacecraft that will carry an Amateur Radio payload. An unusual feature of the spacecraft is its “sail ball” passive stabilization system. The 1.5-U CubeSat is attached to a 500-millimeter flexible film ball — or sail — that will offer passive “pneumatic resistance” stabilization. CAS-7B is expected to remain in orbit for up to 1 month.

The spacecraft will carry an Amateur Radio transponder and educational mission. CAMSAT is working with Beijing Institute of Technology (BIT), a top aerospace school, which is providing launch support in launch of the satellite. BIT faculty and students are participating in the development and testing of the satellite, and, with CAMSAT’s help, the university has established an Amateur Radio club (call sign BI1LG). CAMSAT said many students are now members, “learning Amateur Radio satellite communication and experience[ing] endless fun.”

**  Dubai university ground station to allow students to communicate with, monitor and control SmallSats in orbit: Amity University in Dubai opens satellite ground station on campus – SatellitePro ME

The next phase of this project involves the construction of a 4U (40 cm3) CubeSat in accordance with the UAE’s Environment Vision 2030.

Amity University, Dubai has launched a satellite ground station on their campus, which will allow students to track satellites, predict weather patterns and pollution levels, as reported by Khaleej Times.

The station at Amity University is aimed at garnering the participation of students studying aerospace, electrical, electronics, computer science or nanotechnology engineering.

Commenting on the initiative, Dr Vajhat Hussain, CEO of Amity University Dubai, as quoted by the English daily, said: “The main goal of the ground station is to give students the opportunity to perform the following operations – telemetry data visualisation and storage, antenna control and positioning system, radio communication using very high frequency (VHF) and satellite data analysis. Through this initiative, students will not only learn how to read and analyse such data but also get the support they need for research projects.”

Creating satellites to explore space is no longer just for adults.

At Grace Brethren High School, a group of about 20 students have made it their mission to launch a small satellite into orbit by 2020.

Known as CubeSat, the device contains a payload that can be monitored from the ground and is equipped with small yet strong LED lights that will send satellite-operating information to the mission operations center at the Grace Brethren Space Lab, said Annabelle Hynes, an 18-year-old graduate who worked on the project.

“Being the only girl involved in the spacecraft class and working on CubeSat has been an interesting experience, and we’ve gotten to do a lot of really exciting, hands-on things with this project,” Annabelle said.

“We’re still figuring out the basics, but . . . the plan is to track the satellite from the school and communicate with it. It will be open to other organizations so they can use the data we collect.”

** Australian university team develops antenna for system to allow continuous ground contact with SmallSats in low earth orbit: New antenna system enables 24/7 connectivity to space – The Lighthouse/Macquarie University

Led by Professor Karu Esselle of the School of Engineering, the team has developed an antenna system with a steerable beam which will enable scientific data downloading from spacecrafts to labs on earth 24 hours a day.

As the first move towards rapidly growing space systems, the low-profile antenna system was designed for US company Audacy who launched the world’s first entirely Ka-band CubeSat (a type of miniaturised satellite that can be used for a variety of space applications including earth imaging, astronomy, science experiments, climate monitoring and surveillance) called Audacy Zero into space via a SpaceX Falcon 9 Rocket in December 2018.

Audacy, a company spun off Stanford University and based in California, is developing the world’s first commercial inter-satellite data relay network. Audacy Zero was the first iteration of a radio that will enable Audacy customers’ spacecraft to connect to this network.

“Data from your CubeSat will travel through the relay system down to earth to the internet and cloud,” explains Prof Esselle.

“Without such a space relay network, a CubeSat can be seen from a fixed ground station only for a few minutes per day and that is often not enough to download all the data collected by the CubeSat.

Student and amateur CubeSat news roundup – April.1.2019

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

** Yale student team to build BLAST CubeSat with cosmic ray detector. The NASA sponsored spacecraft will launch in 2020: Student-built satellite to launch into space – Yale Daily News

On March 14, a group of Yale students learned some stellar news — NASA selected their satellite to be launched into space. The announcement marks the first time a Yale undergraduate group will launch a spacecraft.

The team — which consists of members of the Yale Undergraduate Aerospace Association — received the launch grant through NASA’s CubeSat Launch Initiative competition. Over the course of four years, students designed a satellite called BLAST, which stands for Bouchet Low-Earth Alpha/Beta Space Telescope.

** CubeSat SeaHawk-1 with an ocean color instrument was launched on a SpaceX Falcon 9 in December. The SeaHawk team has released the first images from the spacecraft: SeaHawk-1 CubeSat Captures First Ocean Color Image – UNCW.edu.

This first SeaHawk-1 engineering test image (pictured above) was captured by the HawkEye instrument on March 21st, 2019 at 18:47 UT from an altitude of 588 km and superimposed on Google Map data © 2019 Google, INEGI. At the current altitude that SeaHawk is flying, the pixel resolution of the HawkEye instrument is approximately 130 meters (425 feet) giving us an image size of approximately 6000 lines along track (780 km or 485 mi) x 1800 pixels across track (234 km or 145 mi). The true color full resolution closeup of the region from south of Monterey Bay to north of San Francisco (presented below) was produced by combining three of the Hawkeye bands (red band-6 (670nm), green band-5 (555nm) and blue band-2 (443nm).

The project is led by the SOCON (Sustained Ocean Color Observations using Nanosatellites) team at Univ. of North Carolina at Wilmington and also includes NASA, AAC Clyde Space, and Cloudland Instruments. The project was funded with grants from the Gordon and Betty Moore Foundation.

SeaHawk-1 is a 3U CubeSat (size 30x10x10cm and weight 5kg) designed and built by AAC Clyde Space and launched in December 2018 aboard SpaceX Falcon 9. SeaHawk-1 CubeSat was one of the 64 satellites included in the Spaceflight SSO-A Small Sat Express: their first dedicated ride-share mission for small satellites.

SeaHawk-1 is also the first 3U CubeSat specifically designed to carry an ocean color instrument payload (HawkEye). The goal of this proof-of-concept mission is to provide free high-spatial resolution images of Earth’s coastal regions. HawkEye, designed by Cloudland Instruments, is an 8-band multispectral instrument similar to SeaWiFS (one of the most successful ocean color missions to date).

It differs in that: it was miniaturized (10x10x10cm) to fit inside the CubeSat, band 7 was modified to improve atmospheric correction, all bands were designed not to saturate over land, and the entire sensor was built with low-cost, off-the-shelf materials.

** University of Toronto students fund and build CubeSat for space biology experiment: Lofty goals: UTAT gears up for milestone competitions – U of T Engineering News

The Space Systems Division is preparing to launch the first fully student-funded Canadian satellite into orbit. The small satellite, or cubesat — about the size of a loaf of bread — will carry a biological payload and will analyze the behavior of bacteria in space with the aim of assessing the risk of infections during a long-term space mission.

The team has a busy summer ahead: they’ll be testing the accuracy of the sensors on the cubesat, running hundreds of hours of electronics tests and conducting thermal tests to ensure their satellite’s components can withstand the extreme temperatures it will experience in orbit, between -40 and 80 degrees C.

The cubesat is scheduled to launch on the Indian Space Research Organization’s Polar Satellite Launch Vehicle in January 2020.

** More about the Hampton University students developing CubeSat software in a project sponsored by the Virginia Space Grant Consortium:

Hampton University is part of a collaborative project of the Virginia Space Grant Consortium where students from three Virginia universities delivered small satellites to NanoRacks in Houston, to be integrated into a CubeSat deployer (NRCSD), which will be launched into space on April 17, 2019. Four undergraduate Hampton University students worked on the project by developing software to perform analysis on the data that will be received from the satellites.

“Hampton University has always been on the forefront of innovation. The work our students are doing is being recognized and utilized by industry leaders, and we are excited to be part of this collaboration,” said Hampton University President, Dr. William R. Harvey.

The satellites will communicate data to ground stations at Virginia Tech, University of Virginia and Old Dominion University for subsequent analysis using an analytical tool being developed by Hampton University students from the Atmospheric and Planetary Science Department.

More than 140 undergraduate students have been hard at work on the mission since June 2016 as a cross-institutional team. Undergraduate student leaders and team members from physics, electrical engineering, aerospace engineering, mechanical engineering, chemical engineering and computer science disciplines have worked together to make the mission a reality. The students have been coached by faculty advisors and have benefitted greatly from advice from NASA, industry and academic advisors, and NanoRacks, the world’s leading commercial space station company.

Archaeology from Space: How the Future Shapes Our Past

Student and amateur CubeSat news roundup – Mar.25.2019

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

** Arizona student team to build CubeSat with inflatable antenna for NASA program:  UA Student-led CatSat Mission Selected by NASA | UANews

An inflatable space antenna designed by University of Arizona students is one of 16 small research satellites from 10 states NASA has selected to fly as auxiliary payloads aboard space missions planned to launch in 2020, 2021 and 2022.

The selections are part of the 10th round of NASA’s CubeSat Launch Initiative.

CatSat is a 6U CubeSat led by UA students from the Lunar and Planetary Laboratory and various departments including aerospace and mechanical engineeringastronomycomputer science, and systems and industrial engineering.

CatSat is the size of a large cereal box. When fully deployed, the inflatable expands in a bubble gum fashion, forming a sphere three feet across that sticks out from one side of the box. An aluminized spot inside the inflated sphere is used as the communication antenna to beam data back to the Earth. Since Catsat will be in low Earth orbit, the data can be downloaded using a ground station located at the UA.

CatSat is mainly a technology demonstration mission to mature this inflatable concept in Earth orbit. The ultimate goal is to fly such an antenna on an interplanetary mission that Reddy wants to lead to explore small bodies in the solar system.
