BRAC Onnesha: Role of “Team Centurions”

Introduction:

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.

 

Abdulla Hil Kafi:

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.

 

Raihana Shams Islam Antara:

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 Ibn Monowar:

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.

What will BRAC ONNESHA do?

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.

5 CubeSat. JGMNB.

Mission 1: Capture image of Homeland Country

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.

Mission 2: Digi-Singer

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

Mission 3: SEL Detection

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.

Mission 4: Atmospheric Drag Measurement

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.

Mission 5: Precise Satellite Position Detection System

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.

Mission 6: Ground Station Network

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 testing in 360 degree

It has been a wonderful 15 months. In this 15 Month we have successfully Designed, Built and Tested a CubeSat which will be the first for our country. On February 9, 2017 we are handing it over to JAXA for launching. We want you to experience this journey too. Some of the testing were recorded in a 360 camera. We have put together a montage video of it. So grab your favorite VR googles or Smart Phone and enjoy the following compilation, of BRAC ONNESHA testing in 360 degree.

 

Seminar on NanoSatellite

Hey Guys,

Arif sir will come tomorrow at BRAC Univerisity tomorrow to tell you about his latest goal on NanoSatellite technologies. It’ll be awesome. So be sure to join us.
