Mini-satellite built by UVic students to launch in October


University of Victoria college students are making their imprint on house analysis by designing and constructing a miniature satellite tv for pc, often called a CubeSat, to enter the cosmos.

The staff is a part of the Canadian CubeSat Project, began in 2017, and hung out placing the ending touches on its creation at Canadian Space Agency headquarters in Longueuil, Que.

UVic staff member Alex Doknjas, a 27-year-old electrical-engineering graduate, stated there are about 5 full-time folks getting ready for an October launch of the gadget they’re calling ORCASat — quick for Optical Reference Calibration Satellite.

“Also it’s built in B.C. and B.C. is known for orcas, that’s kind of the play there.”

The CubeSat can be packaged in a rocket that’s launched from Florida’s Kennedy Space Center and goes to the International Space Station, which sits at a top of 400 kilometres. There, it’s despatched into house through a spring-loaded gadget and stays aloft for as much as 18 months amassing information that’s monitored and analyzed by the college staff.

When the CubeSat returns to Earth, it is going to fritter away on re-entry.

The house company chosen 15 universities for grants of as much as $250,000 for the nationwide effort. UVic is main one of many initiatives in co-operation with college students from the University of B.C. and Simon Fraser University, and has beforehand earned prime prizes for its entries on the Canadian Satellite Design Challenge.

The principal construction of CubeSats is common from aluminum and they’re usually 10-by-10-by-10 centimetres, or in regards to the measurement of a Rubik’s dice, weigh a few kilogram and can be utilized alone or in teams of as much as 24. But the UVic gadget has a barely totally different design and is a contact greater than the norm — roughly the scale of a two-litre milk carton.

The introduction of smaller parts has made compact satellites environment friendly, and supply a less expensive choice to construct and launch.

“It’s amazing what you can do now with the advancements of technology,” stated Tony Pellerin, supervisor of the mechanical-engineering group on the Canadian Space Agency.

In the early Nineties, a typical satellite tv for pc weighed a tonne. The measurement ultimately dropped to 250 to 500 kilograms, since weight is the prime expense of sending satellites into house. Some weigh much less now.

CubeSats had been developed with college students in thoughts, however companies additionally use the units for their very own missions, Pellerin stated.

Despite their measurement, CubeSats have makes use of starting from carrying new cameras to check their reliability to conducting experiments, like gathering data on magnetic fields to evaluate their use in earthquake detection.

Plans for the CubeSats which might be a part of the coed challenge embody monitoring the Prince Edward Island potato crop to get a greater concept of when to plant.

Dalhousie University’s satellite tv for pc can be launched in October, as effectively, with the opposite 13 set to go in early January.

Work started on ORCASat in September 2018, with UVic taking over the added problem of constructing every little thing themselves, Doknjas stated. The pandemic affected the unique schedule, which referred to as for completion in two years.

“Ninety per cent of the spacecraft is designed, assembled, tested here in Victoria, and we use a lot of local manufacturing to help us out, as well,” Doknjas stated.

Another UVic staff member, 25-year-old fourth-year ­electrical-and-computer engineering scholar Stefan Bichlmaier, stated he joined the challenge simply as he was beginning his diploma.

“Right at the start I didn’t actually perceive the entire engineering course of. I didn’t even realize it was attainable to be a part of a challenge that would go into house.

“Putting something into space does require a lot of certainty into what you’re designing, so being part of that was a good jump start into becoming an engineer.”

Pellerin stated their satellite tv for pc has primary components reminiscent of an influence system made up of photo voltaic panels and batteries, a pc and a radio system for communication with the gadget.

He stated the “science objective” for UVic is to have a satellite tv for pc that features as an “artificial star” — with a laser as its mild supply.

Like actual stars, ORCASat emits mild and is seen with a telescope, he stated, though ORCASat will seem purple slightly than yellow.

While taking a look at stars, you solely understand how shiny they seem to you, not how shiny they really are, Doknjas stated. But because the ORCASat is provided to measure its personal brightness, the UVic staff has two values to check.

“They want to correct for the atmospheric effect on the light,” Pellerin stated. “They can transfer this information to astronomers, who can actually use that information to fine-tune their images when they look at stars.”

Bichlmaier likened the experiment to taking away the “twinkling” impact, attributable to the ambiance, from stars which might be noticed from Earth.

The aim of the challenge is to provide professors at post-secondary establishments an opportunity to introduce college students to an precise house mission, with house company specialists accessible to information the groups.

About 510 CubeSats from 50 nations have been deployed because the first one went into house in 2003. The commonplace measurement for the CubeSat was established in 1999 by professors at California Polytechnic State University and Stanford University.
