GNSS Free
Flight!
Skyat is an add-on device that attaches to aerial vehicles. It provides positioning capability anywhere on land using satellite imagery and computer vision. The device increases UAV autonomy in GNSS-denied environments without additional infrastructure and augments surveillance and situational awareness capabilities.
Standalone
Skyat does not rely on additional infrastructure to enable its operations. The solution is a standalone device; when added to an AV, it does not require any external communication outside the host AV, i.e., positioning can operate in a fully disconnected manner. Surveillance operations can be part of an autonomous mission or available in real-time to the operator via the vehicle's communications link.
Vision Based
Our solution determines the geographic coordinates of the AV and objects in its view (georeferencing) by utilizing onboard geospatial data (satellite or aerial imagery and digital surface models). This innovation enables the solution to provide enhanced positioning and surveillance capabilities to UAVs. It enables operations, including autonomy, in high-risk areas expected to be GNSS-denied or contested.
Versatile
The software stack is based on the Robot Operating System 2 (ROS). Thanks to the modular and configurable nature of ROS the system can be easily adapted or extended for different mission needs. Functionality can be added by loading a containerized image onto the device that contains a ROS node conforming to the solution’s application interfaces.
Our Story
The Wave of Cartographic Intelligence for Autonomous Systems
Next-gen autonomous systems like UAVs rely on satellite-based navigation systems. Signal interference such as jamming, spoofing, or multipath reception puts these systems and their operations at risk. Most alternative solutions suffer from high cost, drift, additional infrastructure needs, or other limiting factors. Our team has over 5 years of experience with vision-based navigation and situational awareness systems. Our platform provides diversification and redundancy to GNSS while unlocking new opportunities for situational awareness.

PROBLEMS WE SOLVE
Taking Away the Pains of GNSS
Autonomous Navigation
Geo-Satellite triangulation is not built for autonomous systems. Any autonomous vehicle requires high degree of positioning confidence that GNSS is unable to provide. Regulation (EU) 2019/947 article 11 and EU Aviation Safety Agency (EASA), requires certification of UAVs. Which underscores the importance of respecting airspace limitations. Similar requirements are found in the EU Aviation Safety Agency (EASA). UAV manufacturers shall be required to have redundant GNSS positioning systems in their products. Skyat is a unique positioning provider as it does not rely on traditional GNSS infrastructure.
GNSS-Denied Environments
UAVs that operate in adversarial environments are vulnerable to GNSS jamming.
Anti-jamming GNSS receivers (the null steering algorithm) may still be susceptible to advanced jammers.
Alternative solutions suffer from drift (loss of accuracy over time or distance), require additional
infrastructure or emit stronger radio signatures. Thier value is limited to improved localization in
GNSS-denied environments. Skyat enables autonomous operations, including but not limited to,
GNSS-denied environments with the option of maintaining complete radio silence.
Survellance and S&R
With ample connectivity, Skyat can be configured to provide real-time augmented situational awareness
and other surveillance capabilities, for example, manual or automated target detection and tracking.
In addition, these aspects are valuable in border security, disaster response, fire management, law
enforcement activities, etc.
Last Mile Delivery
Mass commercial deployment of drones require reliable navigation systems that are precise and safe enough to land in the backyard of a house in a dense urban environment. Skayt supports commercial off-the-shelf platforms and partnerships for use-cases like traffic monitoring, policing, seaport operations, open-air warehouse logistics, asset protection, etc.
Fly Further and Safer with Skyat
The core principle of Skayt is image feature extraction and matching to determine a large number of correspondences between loaded satellite imagery and live camera inputs from the AV. The correspondences are offset according to the digital surface models and filtered to improve georeferencing and positioning estimates. Coordinates for intermediate locations are estimated using interpolation based on the local topology. The position of the device is determined by iteratively solving the perspective n-point pose estimation problem and fusing its results with visual-inertial odometry using a Bayesian approach.
