Onnesha – a 10 centimetre-edged cube-shaped satellite – designed, developed and assembled by three Brac students.


Brac University today received the nano-satellite BRAC Onnesha, the first satellite made by any Bangladeshi university which will be launched into low earth orbit by March.

It is capable of completing one orbit 400 kilometres above the ground in 90 minutes and passing over Bangladesh four to six times every day, the press release reads.

It will allow high quality images of land to analyse vegetation, urbanisation, flood, water resources, forestry and other natural resources from space.

The low-cost small satellite, categorized as NANOSAT, has been purposefully developed to serve academic and research goals, sources said.

Compared to conventional hi-cost communications satellites, NANOSATs are small in size, weigh between one and ten kgs, and can be placed in low earth orbit (LEO), 500 to 1500km above the equator, instead of the more expensive to launch and build geostationary earth orbit satellites, which are placed around 36,000km away from earth.

Bangladesh's first geostationary satellite, Bangabandhu-1, is set to be launched in December, 2017.

Sources at the Bangladesh Space Research and Remote Sensing Organisation (SPARRSO) and at the BRAC University said the NANOSAT venture synchronized well with Bangladesh's first communication satellite as it would help expose the country's young scientists and academics to satellite technology.

BRAC University teamed up with Japan's Kyushu Institute of Technology (KIT) to launch the NANOSAT as early as May next year, Khalilur Rahman, an associate professor of the university's Computer Science and Engineering (CSE) department, told The Daily Star yesterday.

Along with CSE, he said, the departments of Electrical and Electronic Engineering (EEE) and Mathematics and Natural Sciences are also involved in the program.

KIT, of Fukuoka, Japan, has been with BRAC University's NANOSAT launching process since the signing of a memorandum of understanding a couple of years ago.

It will sign a final agreement with Brac University today to launch the NANOSAT through Japan Aerospace Exploration Agency (JAXA) and the International Space Station (ISS).

Erstwhile Soviet Union was the first to launch artificial earth satellite -- Sputnik 1 -- into space in 1957 which too was a low earth orbit satellite.

Khalil said ground station of the satellite has been readied on their campus.

"We're expecting our NANOSAT to proceed from JAXA to ISS in March next year and then launched to the LEO [low earth orbit] within the next couple of months."

Chief Scientific Officer of SPARRSO Hafizur Rahman welcomed the initiative by a private university. He told The Daily Star that going for low-cost NANOSAT was a good approach. "These satellites can purposefully be developed to address specific needs like agriculture, disaster, climate etc."

He said a number of BRAC University students occasionally visited and worked at SPARRSO and the collaboration was fruitful.

Khalil said the role of Arifur Rahman Khan, a Bangladeshi faculty at University of Texas in El Paso, was instrumental in instilling interest to satellite technology among BRAC University fraternity.

Following his post-doctoral research at KIT, Arifur Rahman Khan was appointed as assistant professor of KIT's Laboratory of Spacecraft Environment Interaction Engineering and helped KIT improve its NANOSAT projects in 2013.

During that period, he visited Bangladesh and later Khalil and a few BRAC University students went to KIT and the relationship turned into NANOSAT collaboration through an MoU signed between the two institutions on May 29, 2014.

In April this year, Arifur Rahman Khan has been hired by University of Texas at El Paso as an assistant professor to develop small satellite facilities, similar to KIT, funded by the United State's National Aeronautics and Space Administration (NASA).

What does that mean?....the satellite will be taken to ISS and then launched from there? :unsure:

LOL! Do you think some dedicated rocket will be used to deploy 10cm cube satellite? I'm guessing, someone will tow it up and it will fired like projectile from there.

Possibly.

CubeSATs, weighing around 1 KG or so, can ride on almost any space mission with other larger (say MINI sats around 30 kg or so) LEO satellites. CUBESAT specs developed by Cal Poly have standardized launch procedures for these small devices, often a simple spring-loaded mechanism attached to the outside of space vehicles to jettison them.

Other launch methods can be more elaborate.....

If BD does not intend to have smaller launch vehicles like Indians then there is no point in this kind of project. This is fairly simple to make with some camera in it and some transponder (?)to communicate.

Oh! that's new to me, I didn't know that ISS launches(jettisons) satellites too....

'While cubesats are inexpensive to launch, many of them do not survive long in orbit. ............For synthetic aperture radar missions, cubesats are not the optimal size....said Dirk Wallinger, chairman and chief executive for York Space Systems, a Colorado startup planning to mass manufacture standard spacecraft buses.

York has contracts or letters of intent from customers seeking to buy 33 of its S-class three-axis stabilized satellites designed for payloads of 85 kilograms, Wallinger said. York is selling its basic S-class satellite for $675,000. Customers pay more to add payload flight computers, star trackers and other mission-related hardware.

What’s the perfect size for a small satellite? “The answer is 42 kilograms,” said Martin Sweeting, Surrey Satellite Technology Ltd. founder and executive chairman said at the Small Satellite Symposium here.

Sweeting noted that 42 is also the answer the supercomputer in the science fiction series The Hitchhiker’s Guide to the Galaxy provides when asked the meaning of “life, the universe and everything.”

Sweeting said that a couple of years ago he worked with an Air Force Academy PhD student to create a formula to identify the optimal size for a satellite in terms of its cost, power and, most importantly, its utility. Satellites 'round about' that 42-kilogram size have maximum utility, he said.”

A number of these are certainly a viable alternative for Govt. satellites like our Bangabandhu-1, costing hundreds of millions of dollars, because miniaturized technology is available as an alternative, lowering launch cost in the process.

Well, this is a University project for graduate students. Nice learning opportunity that may also provide important research data for a very low reasonable cost (say around US$20,000 or so with launch).

Sorry, though I don't have much information on Bangladesh, but you're talking about something really bigger than size of nano satellite in discussion here. Can you please provide some insights about current developments regarding rocketry in Bangladesh?

India can launch satellites like buying lunch.

I don't know what was the intent of your message. What was the payload size and weight?
PS: SpaceX will be a lot more cheaper than any other in near future, but, like I mentioned before, don't forget the size of satellite in discussion here.

Arrey Yar. Pehle Batadiya Hota to kal isko bhi saath bhej dete !!

Congrats Guys!! We must all work together for the betterment of this planet and what better way than cooperating through Science. Good Job.

I don't know of any developments.. maybe someone else can comment.

I agree this is a very good plant.
