How a military tragedy led to the invention of GPS





The military has made a lasting impact on your everyday life.

Because the army has invented more products than any other agency, company or organization in history.

You’ll be astounded at how many products – invented by the military – that now sit in your home at this very moment.

You use them when you wake up, when you shower, when you shave, when you dress, when you drive to work, when you cook and when you relax at the end of the day.

The military may be looking for a few good men, but it has created hundreds of everyday products…

Chances are you have some canned food in your cupboard. That was a Napoleon innovation.

An everyday military invention. (Matthew Garand/CBC) Napoleon Bonaparte was a brilliant wartime strategist, and actually became a general at the age of 24.

He once famously said, “An army travels on its stomach.” He realized he was losing more men to spoiled food and malnutrition than he was to muskets and cannon fire.

So in 1795, Napoleon offered a 12,000 Franc reward – which was a fortune in those days – to anyone who could figure out a way to preserve food.

Up stepped a French confectioner named Nicolas Appert, who developed a way of heating food in sealed glass jars. As long as the seal wasn’t broken, the food would last a long time.

With that, the health of Napoleon’s soldiers greatly improved. There were just two problems – glass was heavy to transport and it was fragile.

History gets a little murky here, but it seems another Frenchman invented the tin canning process, but had a British friend file the patent. Once food moved to tin cans, preservation took a huge leap forward that still echoes to this day.

So the next time you buy a can of soup, you can thank Napoleon.

In 1957, Russia did something that put the rest of the world on full alert: it launched Sputnik 1, the first-ever man-made satellite, into space.

As author Peter Nowak says in his excellent book Sex, Bombs and Burgers, Sputnik caught the U.S. with its scientific pants down.

Launching rockets into space in the 50s wasn’t about who could venture farthest from Earth, but rather who could land nuclear weapons closest to their enemy. In other words, the space program was really about military superiority.

But while Sputnik seemed like a Cold War defeat, it actually led to one of the biggest technological breakthroughs of the 20th century.

A ubiquitous service inspired by the military. (David Gunn/CBC) Scientists at MIT noticed the frequency of the radio signals transmitted by the Russian satellite increased as it approached and decreased as it moved away. They realized satellites could be tracked from the ground by measuring the frequency of the sounds they emitted, and conversely, the locations of receivers on the ground could be tracked based on their distance from the satellite.

Using that knowledge, the Navy built the first real satellite navigation system designed to locate submarines in 1959.

Later, in 1974, the military launched the first 24-hour navigation system called NAVSTAR. That technology would eventually lead to the GPS in your car and smartphone.

Access to GPS technology changed forever on September 1st, 1983.

The Korean airliner was en route from New York to Seoul when it apparently strayed into Soviet airspace and was shot down. Not long after, President Ronald Reagan decided that GPS – which could have prevented that tragedy – would be made available for all civilian use.

But – the military worried hostile nations would use GPS technology against them – so they purposely degraded the precision of commercial GPS devices. And if you remember back to the early ’90s, GPS seemed miraculous – but frustratingly inaccurate. That was the reason. Commercial GPS was purposely made to be less than perfect.

Then in the year 2000, the military ended the degradation of GPS signals and navigation became 10 times more accurate overnight. With that, all sorts of companies began manufacturing GPS devices.

The global GPS market generated over $26 billion last year.

From Sputnik to the Korean airline disaster – your GPS has taken a tumultuous journey to your smart phone.

Back in 1942, a group of scientists led by a man named Harry Coover was looking to create a clear plastic that could be used to manufacture precision gunsights for use in World War II.

During their experiments, they stumbled on a formulation that had potential, but the material had one big drawback. It stuck to everything.

An accidental military discovery. (Wikimedia Commons) It was so sticky, it frustrated the scientists. This new formulation, called cyanoacrylate, stuck to everything it came into contact with. As a matter of fact, it was so annoyingly sticky it was rejected as a gunsight solution.

After the war in 1951, Harry Coover was heading up the research department at Eastman Kodak. He and another scientist rediscovered cyanoacrylate one day – and suddenly realized something.

It may not have had wartime applications, but its stickiness might just have some commercial applications. So – in 1958 – they began marketing it as Super Glue.

It became a commercial phenomenon. But eventually Super Glue would find itself back in the war with Vietnam.

Field medics discovered when they sprayed Super Glue over open wounds, the bleeding stopped instantly, allowing injured soldiers to be transported to the hospital for treatment.

Eventually, Kodak licensed the formulation to other companies and you can now find cyanoacrylate in all sorts of products in your home – from aquariums and electronics to fingernail cosmetics.

From gunsights to your fingernails, what a long, strange trip it’s been.

When Ontario declared a COVID-19 health emergency last spring, the first instinct of Ottawa entrepreneur Peter O’Blenis was to preserve cash.

“We basically stopped our discretionary spending,” said O’Blenis, the co-founder and CEO of Evidence Partners, which makes software for accelerating the review of scientific and medical literature, using artificial intelligence. “We cut investments in things meant to help us grow.”

It was a defensive posture born of experience. O’Blenis had 12 years earlier nearly been crushed by the global financial crisis. Another looked to be on the way.

In 2008, O’Blenis and his colleagues, Jonathan Barker and Ian Stefanison, hit a brick wall with their first venture, TrialStat, which helped hospitals manage patients’ electronic data. While TrialStat had secured $5.5 million in venture financing just a couple of years earlier, the founders had burned through most of it during a rapid expansion. When the financial world collapsed, so did their firm.

The trio played things far more conservatively with Evidence Partners, which has relied almost exclusively on customer revenues to finance expansion.

The caution proved unnecessary. Like so many other businesses, O’Blenis underestimated the government’s willingness to keep the economy afloat with easy money. Nor did he anticipate that COVID-19 would prove a significant catalyst for the firm’s revenues so soon.

Evidence Partners is hardly the only local firm with technology particularly suited for the war against COVID-19. Spartan Bioscience and DNA Genotek adapted existing products to create technology for identifying the SARS-CoV-2 virus that causes COVID-19. Ottawa-based units of Abbott Laboratories and Siemens Healthineers make portable blood analyzers that diagnose patients afflicted by the virus.

Shepherds of Good Hope wants to expand ByWard Market operation with eight-storey housing complex





The Shepherds of Good Hope plans to build an eight-storey building near its current shelter for the homeless in the ByWard Market that would include supportive housing for up to 48 people, a soup kitchen and a drop-in centre.

The organization says it wants to be part of the solution to the housing crisis that has fuelled a rise in homelessness in Ottawa.

People would be moved out of the emergency shelters and into their own tiny apartments in the complex, which would include a communal dining hall and staff available to help with mental health, addiction and medical problems, said Caroline Cox, senior manager of communications for the Shepherds.

Some residents in the neighbourhood are opposed, saying services for the homeless and vulnerable should not be concentrated in one area of the city.

“I was flabbergasted,” said homeowner Brian Nolan, who lives one block from the development proposed for 216 Murray St., where currently a one-story building houses offices for the Shepherds of Good Hope.

Nolan said that, in the 15 years he’s lived in the area, it has become increasingly unsafe, with home and car thefts, drug dealing, loitering, aggressive and erratic behaviour, urinating, defecating and vomiting on sidewalks and yards and sexual acts conducted in public on his dead-end street. Before he lets his son play basketball in the yard, he checks the ground for needles and his home security camera to see who is nearby.

Carleton University Hosts the Forum Lecture: Towards a Feminist Post-COVID City





evehe Carleton University Forum Lecture: Towards a Feminist Post-COVID City given by Leslie Kern launches Ottawa Architecture Week. Urban geographer, author and academic, Kern will discuss how the pandemic has highlighted long-standing inequalities in the design, use and inclusivity of urban spaces. The talk will share some of the core principles behind a feminist urban vision to inform a wider vision of justice, equity and sustainability.

: Tuesday, Feb. 23, 2021 at 6:30 p.m.

About the Speaker

Kern holds a PhD in Women’s Studies from York University. She is currently an associate professor of Geography and Environment and director of Women’s and Gender Studies at Mount Allison University.

Kern is the author of two books on gender and cities, including Feminist City: Claiming Space in a Man-Made World (Verso). The book discusses how our cities have failed in terms of fear, motherhood, friendship, activism, the joy and perils of being alone, and also imagines what they could become.

Kern argues, “The pandemic has shown us that society can be radically reorganized if necessary. Let’s carry that lesson into creating the non-sexist city.”
