Precision landing in tight spaces


Klepsydra Precision Landing is a fast-responsive and lightweight on-board software application for UAVs to perform autonomous precision landing in small and constrained spaces. This software product has the following features:

  • Adaptable to several types of sensors.
  • Lightweight and can fit in small on-board computers.
  • Compatible with main UAV autopilots and software frameworks.

Klepsydra precision landing software is used by:

  • UAV companies performing off-shore windmill inspections,
  • Space companies for research on in-orbit-servicing
  • Autonomous Lunar landing.

Core benefits

Zero data losses. Klepsydra can guarantee that any sensor data or communications message is going to be processed.

Real-time processing. Klepsydra can process data in real time with much less latency than other solutions, like ROS.

Predictable applications. It is more stable, predictable and deterministic than other edge solutions.


Less hardware cost. Klepsydra Precision Landing is very lightweight and can be installed in virtually any onboard computer.

Flexibility and compatibility

It can be used with a number of different sensors including:

  • RGB cameras
  • perception cameras,
  • LiDAR
  • RTK
  • Radio and ultra-sound positioning.

Klepsydra is compatible with several frameworks and UAV technologies including:

  • MAVLink, PX4, MAVROS
  • ROS, Gazebo
  • Linux, OpenCV.
