As the space sector experiences rapid growth in satellite operations and diversified space missions, the demand for in-orbit servicing has risen. PIAP Space has met this need with its innovative Docking System, aimed at boosting satellite longevity, serviceability, and sustainability. This system facilitates satellite operators in extending missions, performing essential repairs, refuelling, and managing deorbiting processes, contributing to more sustainable space practices and reducing orbital debris while optimizing satellite investments.

PIAP Space's Docking System consists of two primary operational approaches tailored for different mission needs. The Direct Docking method enables quick and efficient attachment for satellites with compatible structures. The Berthing approach, utilizing the TITAN robotic arm, ensures precise maneuvering and alignment, supporting non-cooperative or unprepared satellites and adding flexibility for various satellite configurations.

Central to the system is the LARIS Gripper, a multifunctional end-effector designed to capture satellites using the Launch Adapter Ring (LAR). With 5 degrees of freedom, it manages misalignments and various LAR types, ensuring effective capture of both prepared and unprepared satellites. The Gripper's design features dual-stage capture to prevent rebound and secure alignment, facilitating stable connections for maintenance, refuelling, or deorbiting.

To maintain stability and manage docking dynamics, the FORTIS (Force and Torque Sensor) is integrated into the system. This sensor detects force and torque at the interface, providing essential feedback for compliant docking and minimizing potential damage through precise force control.

A key component of PIAP Space's Docking System is its 3D Vision System, which determines the position and orientation of the satellite's LAR. This advanced vision system employs algorithms to guide accurate approach and capture, functioning without the need for specialized markers or modifications, making it suitable for varied satellite designs.

PIAP Space's comprehensive approach and modular system architecture cater to the rising needs of satellite servicing, promoting sustainable space operations. The company foresees in-orbit servicing as a core element of responsible satellite management and long-term operational value.

With a robust background in robotics and automation, PIAP Space continues to push forward in enhancing space missions. Their expertise includes an array of satellite servicing technologies such as robotic arms, docking interfaces, and vision systems for in-orbit refuelling and mission extension, supporting satellites from launch to deorbiting.
