The clock is set. Count down for launch begins.

After participating/winning multiple local/national competition/project exhibition, Kafi, Antara & Maisun realized they need a fixed name for their team. The name they picked is, “Team Centurions”. Driven by the passion for science, technology & innovation, they took a leap of faith and dared to build the first satellite of Bangladesh. Not only they had to build their own CubeSat, they had to carry on their own individual space research.
Kafi’s research for his M.Sc. degree has been “Single Event Latchup Measurement”. SEL occurrence is associated with Galactic Cosmic Radiation particle. Outer space is not a complete vacuum. Heavy ion, protons and electron can cause internal short circuit. Kafi’s research will enable us to understand SEL occurrence in space better.
Antara’s research for her M.Sc. degree has been developing a new mechanism for CubeSat Antenna Deployment. Antenna deployment system are usually housed outside. Additionally, nichrome wire consumes a huge amount of power during operation. As opposed to conventional nichrome wire based antenna deployment system, Antara’s design promises more reliability & less risk deployment system.
Maisun’s research for his M.Sc. degree has been Satellite communication for high speed CubeSat mission data downlink. CubeSat usually has a limited communication window. However, CubeSats perform incredibly sophisticated missions now a days. Maisun’s research looks into the possibility of downlinking more data without sacrificing in terms of power or space.
BRAC ONNESHA is a part of the larger Joint Global Multi National BIRD Project. 5 Satellites from 5 country (Japan, Ghana, Mongolia, Nigeria & Bangladesh) will orbit earth and collectively perform 6 Missions.
Natural resource monitoring one of the most used application of satellite technology. The main mission of BIRDS satellites is to capture a picture of respective homeland countries and send it back to respective country’s ground station. BRAC Onnesha has 2 cameras onboard. The primary camera is a 5 MP CMOS camera. We expect it capture 100 km/pixel spatial resolution picture of the earth. The auxiliary 0.3 MP camera serves as a backup camera.
BRAC ONNESHA will broadcast our National Anthem from space. This mission aims to motivate the young enthusiastic minds for career in space engineering. Anyone with a UHF receiver can receive and listen to our national anthem, played from space. For more details: http://birds.ele.kyutech.ac.jp/digi.html
Single Event Latchup or SEL is a phenomenon related to harsh space environment. For Galactic Cosmic Radiation, microprocessors sometimes experiences internal short circuit. This disrupts satellite operation. BIRDS constellation, aims to map SEL events for LEO and provide a statistical database for interested audience.
By using data from all 5 of the CubeSats, BIRDS project aims for measuring atmospheric drag more reliably by observing the decay rate of satellites. This data will provide more in depth data for our atmosphere and its effect on CubeSat mission lifetime.
In addition to 5 countries building satellites, Taiwan and Thailand are also participating in BIRDS project by sharing their ground station. 7 ground station in total enables us to experiment a reverse GPS system. This way, we can track our satellite without using any GPS.
One of the limiting factor for University based CubeSat project is, limited mission life and communication window. A ground station network can effectively increase the communication window. BIRDS project aim to demonstrate such a network operation for CubeSats. Participating countries are, Japan, Ghana, Mongolia, Nigeria, Bangladesh, Taiwan & Thailand.

BRAC ONNESHA launch day has been announced! BRAC Onnesha will be Launched on 2 June, 03:55 am BDT.
The Launcher is Space X’s Falcon 9. It’ll be launched from Kennedy Space Center, Florida. SpaceX will be delivering Cargo to International Space Station. And among the cargo, will be our precious BRAC ONNESHA 😀 😀 😀
You can follow the news by searching “CRS11” on google.
What this means?
Once BRAC ONNESHA is Launched and Deployed, it will be the first Satellite of Bangladesh, orbiting the earth. During it’s 6 months mission, it’ll perform 6 missions. It’ll also be a part of BIRDS CubeSat constellation. It is worth mentioning, BIRDS CubeSat Constellation is also first of its kind.
What do you mean by “Launch” and “Deployment”?
BRAC ONNESHA will be deployed from International Space Station’s(ISS) robotic arm. ISS provides an excellent opportunity for University CubeSat project. Frequent and comparatively cheap launches attract many universities. First, the CubeSat will be “Launched” by SpaceX cargo mission (CRS11). BRAC ONNESHA will be kept inside ISS for few days. The then, it’ll be “Deployed” from ISS’s KIBO module.
When will be the “Deployment”?
We don’t know yet. We are waiting to hear from JAXA.
Why is SpaceX launching? Why not JAXA launcher?
ISS is a shared property among nations. NASA, JAXA & ESA together decides who does what and when. CRS11 has been decided to carried out by SpaceX.
Why is Bangladesh’s satellite being Launched by USA company?
This is Bangladesh’s first Satellite. We don’t have any launchers which can put our satellite into desired orbit.
Who is responsible for building this satellite?
BRAC ONNESHA is a part of BIRDS project. BIRDS project is a collaborative project from Kyushu Institute of Technology. 7 countries in total are partaking in this project. Bangladesh team is simply us (Team Centurions :D). BRAC University is the stakeholder for Bangladesh.
…But I have more questions!
