Automation and artificial intelligence are hot topics these days
This transformation has broad impacts
The Global Navigation Satellite System (GNSS) has become an integral part of modern life, underpinning a vast array of applications ranging from navigation systems in vehicles to precision timing in financial transactions. Its pervasive use means that any disruption to the GNSS service, whether due to natural disasters or intentional interference, could potentially wreak havoc on a global scale. Recognizing the critical importance of uninterrupted positioning capabilities, ECLEXYS is proactively engaged in exploring "beyond GNSS" concepts. These initiatives focus on developing alternative approaches to ensure precise localization even in scenarios where GNSS signals are unavailable or compromised.
Overcoming known limitation of pure GNSS applications
By diversifying its research into complementary
technologies and methodologies, ECLEXYS aims to mitigate the risks associated
with GNSS disruptions and safeguard essential services that rely on accurate
positioning information.
Particular emphasis is given by ECLEXYS Sagl to the wholly new field of Low
Earth Orbit (LEO) satellites as sources of new signals for positioning. This
innovative domain oggers the following advantages:
LEO satellites typically orbit at lower altitudes compared to traditional GNSS satellites, resulting in stronger signals reaching the receiver. This increased signal strength not only improves accuracy but also enhances resilience against spoofing attacks, where false signals attempt to deceive the receiver. The stronger signals make it more challenging for malicious actors to disrupt or manipulate the positioning data.
LEO satellites can provide better coverage and accuracy indoors compared to geostationary GNSS satellites. Their lower altitude orbits allow signals to penetrate buildings and other structures more effectively, enabling reliable indoor localization. This capability is invaluable for applications such as asset tracking, indoor navigation, and emergency response scenarios where precise indoor positioning is essential.
Urban environments with tall buildings often create what is referred to as "urban canyons," where GNSS signals may be obstructed or reflected, leading to inaccuracies in positioning. LEO satellites, with their lower altitude orbits, can mitigate this problem by offering more direct line-of-sight paths to the receiver. As a result, positioning based on LEO satellites tends to be more robust and reliable in urban canyons, improving overall accuracy and performance in densely populated areas.
This forward-thinking approach underscores ECLEXYS's commitment to innovation and resilience in the face of evolving challenges in the field of satellite navigation.
