GPR

We're two weeks away from being fully back to tradeshow seasons with SAE International at #COMVEC. We look forward to collaborating with global experts in the on-highway, off-highway, and defense sectors on advanced solutions to keep #AVs reliable, safe, and efficient in the commercial sector. Noah Gedrimas will represent GPR and look to connect with leaders interested in discussing #localization solutions, maintaining precise and reliable positioning, and safe #autonomousnavigation. Who else is heading to Schaumburg, Illinois? Let's meet!

What are the implications of #mapping and post-processing with GPR's WaveSense system? Noah explains. Learn more about how WaveSense works here: https://bit.ly/3uYKZa1

Why map the subsurface for AV #positioning? 🚧 Roads Change, the Underground Doesn’t: Vehicle surroundings are constantly in flux. Lane markings degrade over time, and potholes require road maintenance. This regular road wear and tear should not impact AV systems. ⛈️ Incomplete Environmental Detection: Sun glare and inclement weather can impact road visibility for automated systems. This is dangerous when snow or heavy rainfall prevents the perception of road markings that help with navigation. 🛣️ Lack of Unique Information: Environments like highways and parking garages can look very similar or lack traditional landmarks—such as signs, aisles, or lampposts—required for visual localization. Subsurface data is as unique as a fingerprint, even on concrete surfaces. Combine that with underground infrastructure, and it’s possible to determine a vehicle’s precise location.

Can we trust self-driving vehicles? That's the question Noah Gedrimas and host Dave Monk discuss on The Friendly Futurist. The challenges of automated driving in edge cases are discussed, along with the future of autonomous vehicles and the reliance on drivers for certain operations. An honest look at current autonomous projects, potential risks and accidents associated with automated cars, and the importance of collaboration to continue creating opportunities across domains.

Ionospheric scintillation can occur daily, disrupting GNSS and the positioning of autonomous vehicles and machinery. One of the greatest benefits of the WaveSense solution is that it does not rely on GPS or GNSS chipsets to provide accurate positioning data. By mitigating the risks associated with GPS failures, WaveSense not only ensures that mining operations can continue without interruption but also contributes to the safety of the environments where these technologies are deployed. This is crucial in industries where even a minor disruption can have significant repercussions. Read the full article, "Innovations in Mining: here: https://bit.ly/3y5JUza

Why GPS alone won't cut it for #selfdriving vehicles. GPS struggles in two of the most common #autonomous driving environments: urban areas and tunnels. The core issue? GPS relies on measuring the time it takes for signals to reach satellites. When those signals bounce off buildings, it throws off the #positioning data. This becomes a critical problem for #autonomy, which requires extremely accurate and reliable positioning—something GPS cannot guarantee in cities, tunnels, or other obstructed areas. Autonomous vehicles cannot rely solely on GPS for safe, level-4 self-driving operations without a human driver. The limitations of GPS highlight the need for complementary positioning technologies, like WaveSense, that can seamlessly kick in when satellite signals are inadequate. www.gpr.com.

Autonomous mobility relies on various sensors to understand surroundings and navigate safely. While technologies like GPS, lidar, and cameras are essential, their susceptibility to interference and failure in certain conditions means they are not enough for reliable positioning. By mapping the subsurface and providing a consistent reference point, GPR complements existing sensor suites and provides reliable localization capabilities during those fail points.

How can we avoid the failure points that traditional sensors suffer from in everyday driving conditions for #AVpositioning? By looking in a completely different direction. A snippet from our interview on the ETech podcast:

Knowing the exact location of a vehicle is key for any journey. Drivers must be able to place themselves on the road and navigate to their destination as efficiently and safely as possible. For an autonomous vehicle to navigate to its destination, it has to localize itself on the road with precise, centimeter-level accuracy every minute of its journey, no matter the weather, time of day, or terrain. Simply put, AVs cannot navigate safely without highly accurate #localization. Because GPS is not always available and computer vision relies on quickly outdated maps, it doesn’t always work. Human drivers can adapt, but not AV systems. Working with the continuously expanding subsurface map, GPR images two to three meters below the surface to create a more detailed map for advanced localization of a vehicle. Integrating uncorrelated, independent vehicle sensors like GPR’s technology into the tech stack provides the most reliable localization for autonomous mobility.

The nature of ground penetrating radar returns is very character-rich. With so much data, it's easy to position. Even when driving in homogeneous operational domains or through concrete. You can listen to the full episode of Car-Chum here: https://bit.ly/3TdnWjW
