Advanced Green Propulsion Solutions for
All Types of Satellites

Thrusters

Monopropellant and bipropellant thrusters powered by high-concentration hydrogen peroxide. Available in different thrust ranges, designed for satellites and spacecraft above 100 kg

Propulsion Systems

Fully customizable propulsion modules designed to meet your mission requirements. From tanks and electronics to thrusters — all developed and manufactured in-house to ensure maximum quality and reliability

Tanks

High-performance propellant tanks, available in two sizes and optimized for high-concentration hydrogen peroxide storage. Each tank can be provided as a standalone component or integrated within a full propulsion system.

Propulsion In Action: Versatile Capabilities for Every Mission

In an era where in-space mobility is becoming a key enabler of the space economy, versatility is essential. Arkadia propulsion systems are designed to perform a wide range of orbital operations.

Our engines combine precision, reliability, and adaptability, making them a core technology for the next generation of space missions.

Technology

Precision Maneuvering With
Green Propulsion

RCS – Reaction Control Systems

Precise attitude and orientation control for satellites, launchers, or servicing platforms.

Arkadia’s monopropellant thrusters (e.g., TRITON 5 N) deliver short, accurate pulses ideal for RCS applications.

Deorbiting and precise re-entry

With increasingly strict space debris regulations, satellites in low Earth orbit must deorbit within five years after mission completion — making reliable and controlled re-entry capabilities essential.

Our engines provide predictable, sustained thrust to safely bring spacecraft back from orbit using green, ITAR-free propellants.

Orbital transfer

Changes in orbital altitude, plane, or position for mission objectives.

Bipropellant engines deliver high-thrust burns for orbital transfers, combined with monopropellant RCS for fine control.

Rendezvous & proximity operations

Close approach and docking with other satellites or platforms.

Arkadia propulsion ensures precise, low-impulse maneuvers, critical for safe rendezvous and servicing tasks.

Flight-proven, launch-ready

As one of the few companies to have successfully flown hydrogen peroxide–based propulsion systems in space, we bring true flight heritage to every mission. This experience allows us to support our customers at every stage — especially during critical operations like on-site fueling at the launch base.

Lead times without trade-offs

With in-house manufacturing and testing, tanks and thrusters are delivered in <6 months, full propulsion systems in <9 — all while maintaining top-tier quality at competitive costs.

Engineering support you can rely on

From early design phases to final validation, our team works closely with customers to ensure full technical alignment. With deep expertise in hydrogen peroxide handling and fully in-house testing capabilities, we guarantee safe, efficient, and reliable system qualification at every stage.

Proven Flight Heritage
DARK

In March 2025, Arkadia’s first propulsion system, DARK, reached orbit for the first time — a historic milestone proving the performance of our green propulsion technology and the capabilities of the entire Arkadia’s team. Launched from the Vandenberg Space Force Base in the US on board of D-Orbit’s ION platform, this mission marked Arkadia as the first company in Europe to fly hydrogen peroxide–based propulsion system to space.
