A small amount of nitrogen fixation can occur naturally through lightning which carries enough electrical energy to break apart N2 molecules, freeing up nitrogen atoms to react with oxygen to produce nitrates.

Since its entrance into the market in 2020, the LOKI Mk2 has been integrated into more than 1,000 teams across six continents, 47 U.S. states, and all ten Canadian provinces. This includes some of the top counter-terrorism units in the world.

Invest in the recovery of nutrients from wastewater and livestock waste to use as fertilizers, closing the circle and promoting efficient use of fertilizers.

The LOKI Mk2 also boasts a range of gear built specifically for its housing and deployment. In collaboration with PROJECT7 ARMOR, another brainchild of Becker’s, Sky-Hero’s LOKI Mk2 can be carried hands-free in the ILB-LOKI backpack, which houses and provides an operating platform for up to two LOKIs. In addition, the PROJECT7 LOKI Vest Integration System (LVIS) is a practical solution for housing the GCS because it mounts directly to armor systems via MOLLE/PALS, providing protection and concealment to the GCS.

In addition to easy deployment—and by easy, we mean it can literally be thrown into the air—the LOKI Mk2 can operate in “happy dog mode,” which allows an operator to fly the drone into a room, turn it over, and switch on its IR lights for night vision.

Although 78 per cent of the atmosphere is nitrogen, this nitrogen exists almost entirely in a form that is unusable by most organisms.

Its on-the-ground partner is the Sigyn Mk1—a purpose-built, rugged ground robot for mission-intelligence gathering over rugged terrain and in difficult-to-reach spaces. Like LOKI, Sigyn features a highly sensitive Day/Night camera, analog operation for secure data relay, and the ability to carry a large array of payloads. Both drone and robot are controlled by the GCS Controller and can be integrated with the Wrist Viewer Gauntlet.

The Haber-Bosch process revolutionized farming globally, but it also marked the start of humanity’s long-term interference with Earth’s nitrogen balance. The amount of reactive nitrogen produced by humans is now greater than the amount created through natural processes. Humans doubled the rates of nitrogen fixation.

Nitrogen pollution is also the byproduct of burning fossil fuels to meet growing demands in the agriculture, transport, industry and energy sectors.

Political momentum for collective action on nitrogen is increasing. The United Nations Environment Programme (UNEP), the leading environmental authority in the United Nations system, is convening stakeholders to tackle nitrogen pollution globally.

But too much of this reactive nitrogen is being lost to the environment. It is polluting water and air, degrading soils, causing toxic algal blooms and creating (dead zones) in the ocean.

The LOKI Mk2 is an essential need within many SWAT and tactical teams because breaching a building comes with a high risk for everyone involved when not much is known about the suspect inside. The LOKI Mk2 can greatly reduce this risk by entering buildings in place of the officers.

Animals eat plants, getting their nitrogen from plant proteins. They pass some of it back into the soil as manure or waste by releasing nitrogen in the form of ammonium. Nitrogen is released in the form of ammonium, which is then converted into nitrates by certain types of bacteria – a process called nitrification.

When nitrogen is deposited on terrestrial ecosystems, a cascade of effects can occur, often resulting in biodiversity declines.

Denitrification is the last step in the nitrogen cycle. It occurs when nitrogen is restored by bacteria into its pure form and released into the air.

In March 2019, the United Nations Environment Assembly - the world's foremost environmental decision-making body - adopted a resolution calling for sustainable nitrogen management. In March 2022, the Environment Assembly adopted a second resolution on the topic.

Excess nitrogen causes nitrogen-tolerant species to thrive and outcompete more sensitive wild plants, fungi and aquatic species. It can cause the inadvertent fertilization of trees and grasslands affecting growth rates and nutrient imbalances, which harm ecosystems and biodiversity.

Together with habitat destruction and climate change, nitrogen pollution is one of the biggest drivers of biodiversity loss on the planet today.

Features of the LOKI Mk2—such as the ability to deliver communications devices for negotiations, locate hazards, and view the layout of the building—can help officers gain further information if they are required to enter the building. With fully shielded rotors and a rugged construction, the LOKI Mk2 can also be crashed without worry.

Reactive emissions can mix with rain to create nitric acid rain, which can damage buildings and sink into the soil harming plants and other living organisms.

Accelerate actions to support the Global Biodiversity Framework Target 7 by reducing excess nutrients lost to the environment by at least half, including through more efficient nutrient recycling and use.

Nitrogen N2

Humanity’s knowledge and understanding of nitrogen has improved rapidly over time. We have learned, for instance, how to extract nitrogen from the air and combine it with other elements such as oxygen, hydrogen and carbon into various reactive forms. These compounds were subsequently harnessed for use in industrial and agricultural activities.

The overarching purpose of the LOKI Mk2 is to make operations for tactical teams safer and more efficient. It was designed for total and virtually effortless integration within special tactics, law enforcement, and military units.

Nitrogen is the most abundant element in our atmosphere. Pure nitrogen must be chemically bonded with other elements, either naturally or artificially, for it to be usable for most organisms.

Sign up to the 2019 Principles for Responsible Banking; and the 2012; and the 2006 Principles for Responsible Investment.

It is therefore critical that governments accelerate actions and legislation to significantly reduce nitrogen waste globally by 2030 and promote sustainable nitrogen management. This could lead to billions of dollars in savings, while benefiting the environment, biodiversity and human health.

Recently, the quadcopter appeared in the Amazon series, The Terminal List, when a soldier deploys a sUAS known as the LOKI Mk2 to track down a character played by Chris Pratt. While it's cool to see the LOKI Mk2 take to the skies in the series, its actual use cases are lower to the ground and more interesting than any Hollywood script.

These seep into the soil in raindrops, providing plants with a form of nitrogen they can absorb via their roots. But most nitrogen fixation in nature occurs through bacteria found in soil and water, or on the roots of legumes, such as beans and peas.

According to a recent study, ecosystems such forests, heaths and surface waters are more sensitive to atmospheric nitrogen pollution than previously thought.

One of the first links between reactive nitrogen and human health was found with high levels of nitrate in drinking water in the 1940s. Infants whose formula was mixed with water containing high concentrations of nitrate had a high risk of developing methemoglobinemia, known as “blue baby syndrome”.

This cycle starts with nitrogen fixation - when atmospheric nitrogen, or pure nitrogen, is converted into nitrates which plants use to make proteins that are needed for their healthy growth. In nature, nitrogen fixation is done through lightning and nitrogen-fixing bacteria.

Until a century ago, natural processes of nitrification and denitrification were fairly balanced. But today this balance has been lost, largely a result of human activity, with serious consequences for our planet.

Effects: N2O is a greenhouse gas - 300 times more powerful than carbon dioxide. It also causes the depletion of the stratospheric ozone layer, which shields humanity from the sun's harmful ultraviolet radiation.

Wildfires and the burning of forests can also increase emissions of nitrogen oxide (NO), a harmful component of smog, and nitrous oxide (N2O), a potent greenhouse gas, known collectively as NOx.

Reducing reactive nitrogen would prevent millions of premature deaths, avert debilitating illness, contribute to food security, while helping to protect wildlife and the ozone layer. There is no single solution to reducing nitrogen pollution. But everyone can play a part in stopping it from poisoning our lakes, rivers, air and soil.

The Haber-Bosch process revolutionized farming globally, but it also marked the start of humanity’s long-term interference with Earth’s nitrogen balance.

Recognized with an Innovation Award at Milipol Paris 2021, the LOKI Mk2 is the first drone of its kind to be purpose-built for the unique function it performs—to serve special tactics teams in a highly secure way.

Industrial and agricultural activities have more than doubled the amount of reactive nitrogen in the environment, impacting water bodies, biodiversity and humans everywhere.

It is therefore critical that governments accelerate actions and legislation to significantly reduce nitrogen waste globally by 2030 and promote sustainable nitrogen management. This could lead to billions of dollars in savings, while benefiting the environment, biodiversity and human health.

Liquid nitrogen

The real LOKI Mk2 from Sky-Hero is designed less for the skies, and functions instead as the eyes and ears in close-quartered indoor spaces for tactical teams in law enforcement and the military. Videos on social media of the LOKI will show footage of it sneaking through tight crawl spaces and under tables.

Nitrogen pollution especially impacts in the marine and coastal environments, where excess nitrogen can lead to algae blooms and oceanic dead zones, that are growing both in scale and frequency.

Replace conventional agriculture with agroforestry and agro-ecological practices such as mixed farming to support biodiversity.

Oxygen

Nitrogen is in the soil under our feet, in the food we eat, and in our DNA, the building blocks of life. Without it, there would be no life on Earth. Nitrogen helps to make croplands fertile and is a key component of protein, which all living organisms need to grow.

There has been limited public discussion about the need to take action to #BeatNitrogenPollution to mitigate climate change. But it's an issue we cannot afford to ignore. If we don't limit nitrogen pollution now, we will face a cascade of negative impacts that jeopardise the environment, the economy, our well-being and livelihoods -- from degraded ecosystems to polluted soil, water and air, and species loss.

When it comes to tackling climate change, most of the world's attention has focused on reducing carbon dioxide emissions - yet nitrous oxide is 300 times more potent. In the past four decades, nitrous oxide emissions have risen by 30 percent.

The discovery a century ago of the Haber-Bosch process that converts nitrogen in the air to ammonia made the manufacture of nitrogen fertilizers possible at an industrial scale and was followed by a spectacular increase in global food production.

In its pure form, nitrogen is not usable for humans, animals and plants. In its reactive forms however, it becomes accessible and creates impacts at each stage of the nitrogen cycle, moving through the air into the soil and living organisms.

Effects: NH3 causes eutrophication and affects biodiversity. It forms particulate matter in air which affects health. This can cause shortness of breath, affect lung function and exacerbate respiratory diseases such as asthma.

One of the main drivers of nitrogen pollution has been the rising consumption of nitrogen-based fertilizer, which doubled between 1978 and 2014 globally.

Nitrogen pollution is also the byproduct of burning fossil fuels to meet growing demands in the agriculture, transport, industry and energy sectors.

Today, about 80 per cent of reactive nitrogen – estimated to be worth US$200 billion – is lost to the environment every year.

Humans are responsible for producing most reactive nitrogen that ends up as pollution, yet the full scale of the problem remains largely unknown outside scientific circles.

Harness ecological processes to manage soil fertility (for example, through crop rotation) and use methods such as no-till farming to limit the disturbance of natural habitats and processes.

Nitrogen ion

In the early 20th century, two German chemists – Fritz Haber and Carl Bosch – developed a way of converting nitrogen (N2) and hydrogen (H2) into ammonia (NH3), using high heat and pressure. Their discovery spurred the mass production of nitrogen-based fertilizers, helping to boost crop yields and sustain an expanding world population.

Molecular nitrogen (N2) is made up of two nitrogen atoms tightly bound together. The strong triple bond between the atoms makes it extremely stable and chemically unreactive.

Since it is not nitrogen per se but excessive reactive nitrogen that is a threat, we must urgently improve our management of the nitrogen cycle to avoid inefficiencies and waste.

However, the LOKI Mk2 went through years of technical refining at Sky-Hero to get to where it is today. Mk2 is the second generation of the widely used LOKI Mk1—which was the first sUAS specifically built for indoor tactical use. But the Mk1 couldn’t be operated by just anyone—it required an expert drone operator for flight. Additionally, it didn’t have the stabilization capability of its successor. The Mk2 features plenty of upgrades, but one of the most significant is its easy deployment and operation. For Sky-Hero, Becker, and AARDVARK, another significant improvement came in the form of a tactical robotics suite.

Effects: It forms particulate matter in air and affects health when ending up in groundwater, causing what's known as blue baby syndrome. In water, it also leads to eutrophication.

In Asia alone, this doubling happened in just 27 years, between 1987 and 2014. Today, almost half of the world's population relies on fertilizers for food production.

An estimated 77 per cent of people breathe annual average concentrations of nitrogen dioxide beyond safe levels. Agricultural ammonia emissions combined with pollution from vehicle exhausts can create extremely dangerous particulates in the air, which can exacerbate respiratory diseases. There is also growing evidence of a connection between reactive nitrogen in air and several types of cancer.

What makes the LOKI even more unique is its seamless relay. The drone is operated via a highly efficient Ground Control System (GCS)—an entirely analog controller that has no lagging or freezing issues, preventing crashes and ensuring real-time intelligence. A single GCS can operate multiple LOKIs, allowing one pilot to gather intelligence on several areas at once. At the same time, other operators can follow the mission through the GCS or a unique Wrist Viewer Gauntlet.

Nitrous oxide (N2O) from industry and combustion is a greenhouse gas, 300 times more powerful than carbon dioxide and has been proven to deplete the ozone layer.

“We’re very excited about the capability that Loki Mk2 can bring to our operators," said Becker. "Although consumer sUAS systems certainly bring enhanced capability, there is nothing on the market that is purpose-built for tactical operations like LOKI. This system allows a pilot to put a camera anywhere, which prevents having to put an operator in harm’s way. I’m convinced this system will save countless lives.”

Livestock waste, also contributes to nitrogen pollution. The livestock sector currently emits 65 teragrams (Tg) of nitrogen per year, equivalent to one-third of current human-induced nitrogen emissions. Of that amount, 68 percent is associated with feed production.

“You can bounce it off walls and ceilings, fly it into attics, crawl spaces, under duct work—you can even fly it under furniture,” Aardvark Tactical CEO Jon Becker told Police magazine [Aardvark is the exclusive distributor of LOKI Mk2 in North America]. “Indoor tactical flight is a full-contact sport and often bouncing Loki off of the walls and floor is required to reach the objective.”

LOKI Mk2 was developed in NATO and NATO-allied countries in conjunction with several of the world’s top counterterrorism units. It is a rugged sUAS that can operate in a completely denied environment without internet service, GPS, phone or tablet connection, or cellular service.

“The best thing about LOKI Mk2 is it just works,” a tactical drone team leader said. “In any environment or any circumstance, LOKI can get our team the information we need. It can be up and flying in seconds, and it can fly anywhere.”

The amount of reactive nitrogen produced by humans is now greater than the amount created through natural processes. Humans have doubled the rates of nitrogen fixation.

The LOKI also requires no operator training for use. Its rugged, user-repairable cloverleaf body means it can take a beating and keep on ticking. It's even able to self-right in the event of a crash. Most importantly, it's mission capable in seconds. It can transition seamlessly from light to complete darkness with its forward-facing .0008 lux day/night camera.

Atmospheric nitrogen can be made usable or ‘reactive’ through natural processes, like nitrogen fixation by legumes, such as soybeans, or artificially through industrial processes.

Invest in the recovery of nutrients from wastewater and livestock waste to use as fertilizers, closing the circle and promoting the efficient use of fertilizers.

Embrace sustainable agriculture techniques that emulate nature to preserve soil fertility, prevent pollution and protect biodiversity.

With an atmospheric lifetime of up to 200 years, nitrous oxide poses a much more long-term threat than other forms of pollutants.

The LOKI Mk2 can be sent into buildings, rooms, or any potentially risky situation, and the worst thing that can happen is that the drone will be shot down. The LOKI Mk2 puts operator safety first by going first, and that is no small thing.

Nitrogen gas

It leaches into soil, rivers and lakes and is emitted to the air. In some forms, nitrogen contributes to ozone depletion and climate change.

Sustainable nitrogen management is needed to live in harmony with nature on a planet that is pollution-free and climate-stable. It is essential to achieving the Sustainable Development Goals and securing a cleaner, healthier environment for future generations.

Excess nitrogen in soil that plants cannot absorb leach into groundwater, contaminating it. This results in the rapid growth of algae which block sunlight to aquatic plants causing them to die. In the decomposition process the plants rob the water of oxygen and the lake, river or stream becomes ultimately lifeless. This eutrophication causes widespread shifts in species and biodiversity loss.

50 per cent of nitrogen fertilizers added to farm fields ends up as pollution. Through denitrification some is turned back to N2.

Nitrogen oxides are a group of air polluting chemical compounds, including nitrogen dioxide and nitric oxide. They are generated from coal power plants, factory emissions and vehicle exhausts. At high concentrations they can lead to smog - and ground-level ozone.

When most people think about Small Unmanned Aircraft Systems (sUAS) in the context of law enforcement, dystopian images are likely what come to mind. The influence of popular media has played its part in this, such as when movies or television programs feature quadcopters that conduct unwarranted surveillance and chase down protagonists with lethal weapons.
