Smoke from the Canadian wildfires continues to pollute the air across the United States, mainly affecting cities in the northeast, including Pittsburgh, Chicago, Cleveland, Detroit and Buffalo.
According to the New York Times, in early June, the level of particulate matter in the air from smoke became so unhealthy that many U.S. cities set records. Visibility decreased in many cities as well, with the smoke creating an orange haze.
Most of the smoke can be attributed to several fires burning across Canada. Many of these fires were caused by lightning; however, with above-average temperatures and dry conditions, wildfires have been breaking out since May.

Based on data from the Canadian Interagency Forest Fire Centre, there are 480 active fires in Canada: 252 are out of control, 77 are being held in place, and 151 are under control.
The fires are mapped in the image below.

Understanding air quality importance
The Air Quality Index (AQI) measures the density of five pollutants: ground-level ozone, particulates, carbon monoxide, nitrogen dioxide, and sulfur dioxide. It was originally established by the Environmental Protection Agency to communicate the cleanliness of the air Americans are breathing every day.
The index runs from zero to 500 — the higher the number the more polluted the air is.
Effects of air pollution can range from mild symptoms, such as eye and throat irritation, to serious ones such as heart and respiratory issues. Pollution can cause inflammation of the lung tissue and increase the vulnerability to infections.
During wildfires, fine particles in the soot, ash and dust can fill the air.
The AQI identifies the concentration of particles smaller in diameter than 2.5 μM. When these particles are inhaled, the tiny specks can increase the risk of heart attacks, cancer, and respiratory infections — especially in children and older adults.
Below is an updated map of air quality from the U.S. AQI as of June 28.
The colors on the map range from yellow — which is unhealthy air quality — to purple, meaning the air quality is hazardous. (Image: AirNow.gov)

What positioning technology is right for your UAV?
One of the things to evaluate is accuracy. Accuracy is important for two reasons: you want your UAV to be where it’s supposed to be, and you want to be able to accurately georeference the data you’re gathering with your payload. But (as you will no doubt have already discovered), accuracy isn’t as simple as looking for a number. You’ll have spotted various abbreviations accompanying those numbers — GPS, PPK, RTK, and GCP most commonly, but you may also see GNSS thrown into the mix. In this article, OxTS will explain what these abbreviations mean, and what they mean for your UAV project.
What are GCPs?
GCPs stands for ground control points, and they are the most inexpensive method of ensuring your data is accurately georeferenced. They are physical targets that you place on the ground, and for which you know the coordinates. Once your UAV has finished its survey, those points can be used to reference the position of your UAV in the global frame.
The biggest drawback with GCPs is that they don’t help your UAV know its own position. GCPs only help provide your UAV with a general position reference. So, GCPs aren’t any use if you want your UAV to fly pre-programmed flight plans. For that, you’ll need a solution such as an inertial navigation system (INS) paired with a GNSS receiver. GCPs can also be time consuming to use and cause additional difficulties at the post-processing stage.
What is GNSS?
GNSS stands for global navigation satellite system, which are systems that use satellite-based radio navigation to provide positioning, navigation and timing anywhere on Earth. The U.S. GPS is one of four GNSS constellations; the other three are the Russian GLONASS, the Chinese BeiDou, and the European Galileo. There are also two regional satellite navigation systems — the Indian NavIC and the Japanese QZSS.
Many UAVs will have a GNSS receiver built in — it’s what enables them to know where they are on the planet, after all. Using GNSS only, most UAVs can get accuracy of 3 m to 5 m. This level of accuracy isn’t too bad for some applications, but not accurate enough if you’re trying to use the position data for mapping activities.
What is PPK?
Most UAVs advertise their ability to perform PPK — which stands for post-processed kinematics. It’s a method of squeezing extra accuracy out of your GNSS signal. OxTS has a blog post here that describes how it works.
The main thing to note about PPK is that you can’t use it in real time. UAVs with PPK capabilities can provide data that’s centimeter-level accurate in optimum conditions, but that accuracy can’t be used for navigating the drone itself. It also means that for activities that require centimetre-level accuracy in real time, PPK doesn’t deliver.
What is RTK?
RTK is the best you can get when it comes to position accuracy. RTK stands for real-time kinematic, and just like PPK it can use it to obtain centimeter-level accuracy — but, in real time, rather than in post-processing.
For most mobile mapping activities RTK accuracy is the goal, particularly if you’re using a lidar sensor to create georeferenced pointclouds.
Without RTK accuracy for the duration of your lidar survey, your point cloud may be unusable. The additional accuracy RTK offers could be used to tackle more challenging environments — providing that you have the tools to remain with RTK accuracy for as long as possible in the absence of GNSS.
Most off-the shelf UAVs won’t have RTK capabilities built in; however, to get this level of accuracy, it’s likely that you’ll either need to purchase a top-of-the-range UAV or invest in a custom UAV (either built by you, or by a professional company).
What’s right for me?
If you’re involved in mobile mapping activities, then at the very least you will need PPK capabilities. Without those, you won’t be able to georeference your data with enough accuracy to be of use to anyone.
When considering the difference between PPK and RTK, you need to consider:
In what environment is your UAV operating? Do you need more accuracy than just a GNSS signal (remembering that PPK can only be applied after the survey takes place)?
Is range of no particular importance – or is the payload on your drone sufficiently large that you need to calculate range very carefully? If so, RTK will give your UAV additional accuracy and, therefore, fuel efficiency.
The final word in accuracy: gx/ix PPK and RTK from OxTS
If you read the blog post mentioned above, you’ll know that RTK (and PPK) rely on having an optimal number of satellites visible. If those satellites are lost, then so is RTK lock. That is, unless you use an OxTS INS with gx/ix tight coupling technology. Gx/ix allows our INS devices to maintain RTK and PPK level accuracy even if the number of visible satellites starts to drop. Essentially, it protects the accuracy of your scan for longer — and it is available on the OxTS xNAV650, our UAV-mountable INS.
The OxTS xNAV650 INS combines a best-in-class inertial measurement unit, with a survey-grade GNSS receiver to output highly accurate navigation data (position, heading, pitch and roll). The xNAV650 is used across the world for applications where reliability and accuracy are critical.
Air Mobility Event Illustration. (Image: Paris Air Show)
The Paris Air Show
The Paris Air Show rolls out this week, accompanied this year by several urban air mobility (UAM) companies, including Eve Air Mobility with a cabin mock-up of its eVTOL, and demonstrations of its UAM software.
Eve also announced ahead of the show that United Airlines, its major partner, is moving forward with route and infrastructure planning in San Francisco — where such factors as the size of the city and high traffic volume cry out for mobility alternatives.
Eve UAM. (Image: Eve press release)
Emerging as a start-up from within the Brazilian aircraft company Embraer, Eve was eventually floated in 2022 through an initial public offering on the New York Stock Exchange. Given the relationship with Embraer, Eve (in particular, United and other Eve customers) stand to gain access to the worldwide maintenance, support, parts and repair organization that Embraer has developed to support its own passenger fleet of thousands of aircraft. An enviable solution for any current or future purchaser of Eve vehicles — this probably has something to do with their huge order backlog for 2,770 vehicles. All that is required now is the full-scale assembly, ground and flight test, verification and certification of the Eve air mobility aircraft — currently forecast to enable a 2026 entry into service.
Additionally, other UAM companies will be present in a special show exhibit, the “Air Mobility Event,” in Hall 5 in Paris.
Is Ukraine winning the UAV war with Russia?
This is not at all clear, as both sides throw at each other many different UAVs in various configurations with different missions. We tend to only see the Ukraine side of the picture, given that Russia does not generally document its successes in the media.
However, recent news indicates that Moscow is importing Iranian UAV technology to bare in its war with Ukraine. It seems that Iran has been supplying complete kamikaze attack UAVs and may also be assisting with materials to set up an assembly plant near Moscow. Potential one-way attack UAVs include the HESA Shahed 136/Geran-2, the new MERAJ-523 which can carry a 50 kg warhead, and the Mohajer-6 reconnaissance/attack drone.
Last week, Russia unleashed a volley of about 44 UAVs on the capital Kyiv, thought to be Shahed 136 kamikaze UAVs. Ukrainian defenses brought down the majority, but there were still a number of casualties. These attacks on the center of Kyiv are said to have intensified during the last two months — the UAVs are cheap, long range, and carry significant ordinance.

The UK is reported to have called Iran’s actions in support of Russia contrary to the nuclear agreements reached between Iran and the European Union in October 2022, which prohibit the supply of any military aid to Russia by Iran.
Not to be left behind, India has brought its own kamikaze UAV online
The ALS-50 loitering munition, built by the Mumbai Tata group, was recently inducted into the Indian Air Force (IAF) for use against targets on the ground (i.e., missile batteries) and on the sea (i.e., ships).
With an apparent range of 1,000 km (62 miles) and a payload of 25 kg (55 lb), the Indian-produced UAV will replace more expensive UAVs, which India has imported from Poland and elsewhere.
With the war in Ukraine on the mind of all countries near the conflict, it is clear that many may take on defense strategies similar to those that have been used by both Russia and Ukraine.
UAV news summed up
So, as the International Paris Air Show, previously a major military exhibition and air show, begins to welcome and feature the coming age of UAM, it is good to see that there are several independent programs that plan to show their wares. Air-taxi services are still some way off from being a reality, as there are still heavy, lengthy investments to be made in building and qualifying these unmanned/manned aircraft for passenger use. Hopefully, however, several of the contenders will make it to the finish line and fulfill the promises made for UAM.
Meanwhile, as the war in Ukraine plods along, taking lives and destroying property, it is good that both sides have decided that UAVs should be the way to proceed. UAVs, after all, are relatively small and the degree of destruction they can cause is limited. Still, this is not very comforting for people on both sides as they run from the sound of two-stroke and four-stroke engines descending from on high, carrying explosive charges that will kill and maim. Additionally, as the West arms Ukraine with defensive materials, it’s not surprising that Russia is seeking weapons from allies, wherever it can find them.

Point One Navigation and Septentrio have partnered to expand upon the companies’ precision location solutions throughout Western Europe. The new developer compatibility is suitable for demanding applications, including industrial autonomy, precision agriculture, logistics and delivery, robots and autonomous vehicles.
Point One’s Polaris is a correction network that enables high-precision GPS and computer vision-based localization. Polaris has recently extended coverage to now include Western Europe, further expanding the reach of the network. This solution is powered by Septentrio’s GNSS receivers, including the mosaic compact multi-constellation GNSS receiver.
The mosaic module — a multi-band, multi-constellation receiver in a low-power surface-mount module with a wide array of interfaces — is designed for mass market applications such as robotic and autonomous vehicle guidance systems. The module integrates GNSS and RF ASIC technology, as well as the robust positioning engine from Septentrio.
Septentrio real-time kinematic (RTK) receivers can be used directly with Polaris to provide centimeter-level accuracy in seconds.
This technology is complemented by Point One’s FusionEngine software, which further integrates cameras and additional sensors to achieve the desired level of precision — even in the complete absence of satellite signals.
FusionEngine has the accuracy and the resilience to inclement weather required by Level 2 applications, such as highway lane keeping and V2X, while offering the robustness necessary for mission-critical Level 4 and Level 5 robotaxi and full autonomy applications.
