PIAP Space Advances Satellite Docking Technology for Refuelling, Maintenance, and In-Orbit Servicing

18 listopada 2024

Warsaw, Poland, November 18,2024 – As the space industry witnesses unprecedented growth in the number of operational satellites and expands its commercial and scientific activities, the need for effective in-orbit servicing solutions has become increasingly urgent. PIAP Space has responded to this demand with its advanced Docking System, designed to significantly enhance satellite longevity, serviceability, and overall mission sustainability. Through this Docking System, PIAP Space enables satellite operators to extend mission lifespans, perform critical repairs, conduct refuelling operations, and manage end-of-life deorbiting processes more effectively. This capability supports sustainable practices in space, helping to address the challenge of orbital debris while maximizing the return on investment for satellite stakeholders.

The Docking System developed by PIAP Space is structured around two main operational architectures, each addressing specific mission demands. The Direct Docking approach offers a rapid, straightforward docking solution for satellites with compatible interfaces. In contrast, the Berthing method, supported by PIAP Space's TITAN robotic arm, provides precise handling and alignment for unprepared or non-cooperative targets, enhancing flexibility for diverse satellite configurations.

PIAP Space's Docking System relies on key components to ensure secure, efficient, and adaptable docking. At its core is the LARIS Gripper, a versatile end-effector engineered to capture client satellites via the Launch Adapter Ring (LAR). With 5 degrees of freedom, it can manage significant misalignments and accommodate various LAR configurations, making it practical for capturing both prepared and unprepared satellites. The Gripper's design includes soft and hard capture stages that prevent rebound, ensure alignment, and establish a stable connection during maintenance, refuelling, or deorbiting operations.

To enhance stability and control during docking, the system incorporates the FORTIS (Force and Torque Sensor), which measures forces and torques at the docking interface. This allows for precise detection of contact events and provides feedback necessary for controlled, compliant docking, even in dynamic scenarios. The FORTIS supports force and torque control, reducing the risk of damage and ensuring reliable attachment.

The Docking System also includes a 3D Vision System that plays a crucial role in identifying the exact pose of the target satellite's LAR. The system calculates the LAR's position and orientation using advanced algorithms, enabling accurate approach and capture maneuvers. This vision-based capability is compatible with various satellite designs, requiring no specific markers or modifications, making it adaptable for a wide range of missions.

PIAP Space's Docking System addresses the emerging needs of satellite servicing and maintenance through these components and modular architecture, contributing to a more sustainable space environment. The company envisions a future where in-orbit servicing becomes central to responsible space asset management and prolonged operational utility.

With a strong foundation in robotic and automation solutions, PIAP Space is dedicated to advancing space operations. The company's expertise spans a comprehensive portfolio of satellite servicing technologies, from robotic arms to docking interfaces and vision systems designed for in-orbit refuelling and life extension. This expertise supports the full lifecycle of satellite operations, including maintenance, repair, and end-of-life deorbiting.

PIAP Space is a Polish governmental company established in 2017. PIAP Space is an EU leader in space robotics systems for orbital and planetary solutions. The company developed the robotic arm TITAN for ESA and different end-effectors such as grippers for In-Orbit Servicing. The LARIS gripper, developed in the EROSS + project, for catching the LAR of the satellite is currently the most advanced subsystem in the EU. PIAP Space has wide experience in European collaboration projects and as a WP Leader, for instance, EROSS, EROSS+, and EROSS IOD/SC, I3Ds, and PRO-ACT projects for Horizon Programs. PIAP Space is also prime for ESA projects in the area of space robotics, such as TITAN (development of robotic arm for IOS – just finished at 5/6 TRL), MANUS (robotic manipulator breadboard for ARGONAUT mission), INORT (Feasibility Study and Roadmap for critical technologies in In-Orbit Refuelling), RAVEN (Feasibility Study for national Orbital Transfer Vehicle) as well as ESA project. PIAP Space is also a provider of the LARIS gripper for the ENDURANCE mission coordinated by Infinite Orbits for CNES.
