Orbital Fuel Stations in Space (On-Orbit Services)
Orbital Fuel Stations in Space offers on-demand life extension services for space assets, including refueling, docking, repair, and inspection, to improve maneuverability and extend mission lifespan.
Description
Orbital Fuel Stations in Space provides a suite of on-orbit services designed to extend the life and enhance the functionality of space assets. These services include safe, controlled on-orbit propellant transfer for mission life extension and improved maneuverability. The platform also offers precise autonomous or assisted docking capabilities for refueling and other servicing activities. In-orbit repair and restoration services are available to correct anomalies and extend spacecraft functionality and lifespan. Furthermore, high-resolution imaging and sensor-based inspections are provided to assess spacecraft health and identify anomalies without disrupting operations. The company is actively developing solutions for On-orbit Life Extension through reliable in-space refuelling, Active Debris Removal to enhance orbital safety, On-demand Mobility for flexible on-orbit maneuvering, and Satellite Inspection for accurate evaluation of spacecraft status. Flight heritage includes the Zero-G1 mission in November 2024, which demonstrated RPO and propellant transfer, successful docking and fluid transfer under microgravity, qualification of SIDRP (Standard Interface for Docking & Refueling Port), controller-based refueling, and PnP/EPnP pose-estimation algorithms. The Zero-G2 mission in May 2025 focused on autonomous docking and fluid-transfer mechanisms with fluid-slosh dynamics, advanced CNN-based pose-estimation for dynamic targets, and integrated docking sensors with end-to-end SIDRP functionality in microgravity.
