From concept to orbit, satellite missions demand precision, reliability, and partners who understand the realities of space. At ESI Motion, we design and deliver space-rated motion control systems, satellite power solutions, and advanced energy storage technologies purpose-built for modern satellite applications—helping mission teams reduce risk, increase performance, and meet demanding timelines.

Whether supporting small satellites, CubeSats, or complex spacecraft operating in Low Earth Orbit (LEO), Geostationary Orbit (GEO) or any other orbit; ESI Motion is here to ensure your spacecraft moves, powers, and performs exactly as intended.

Built for the Harsh Reality of Space

Space is unforgiving. Extreme temperatures, radiation exposure, and the inability to service hardware once deployed mean every component must work flawlessly—every time.

ESI Motion’s space-qualified motion control and power systems are engineered from the ground up to thrive in these conditions. Our solutions undergo rigorous testing to meet spaceflight hardware requirements, delivering dependable performance across launch, deployment, and long-duration on-orbit operations.

Comprehensive Solutions for Satellite Platforms

Satellite programs benefit from partners who can simplify integration and reduce supplier complexity. ESI Motion offers a broad portfolio of satellite subsystem solutions, including:

• Motion Control Systems for Satellites – Precision actuators and servo drives for space applications designed for antenna pointing, solar array deployment, and robotic operations
• Satellite Battery Systems & Power Electronics – Advanced energy storage solutions like SatBat, a space-rated battery optimized for high cycle life, extreme temperatures, and long-duration LEO satellite missions
• Integrated Satellite Electronics – Smart systems with built-in telemetry, monitoring, and protection to support autonomous spacecraft operation

By delivering tightly integrated spaceflight-proven satellite components, we help spacecraft developers reduce mass, improve efficiency, and streamline system-level design.

Optimized for Modern Satellite Missions

Today’s satellites must do more with less—less mass, less volume, and less margin for error. ESI Motion’s technologies are optimized to support next-generation satellite missions by enabling:

• High cycle life batteries for satellites
• High depth-of-discharge (DoD) energy storage without degradation
• Wide temperature operation for space electronics
• Reduced SWaP (Size, Weight, and Power) for satellite systems

These capabilities are especially critical for LEO satellite constellations, where reliability, scalability, and cost efficiency directly impact mission success.

A Partner, Not Just a Supplier

At ESI Motion, we believe successful satellite missions start with collaboration. Our team works closely with customers early in the design phase to deliver custom satellite motion control solutions and space power systems tailored to mission requirements.

This partnership approach allows us to support spacecraft programs from early development through launch and on-orbit operation—reducing technical risk and accelerating time to mission readiness.

Flight-Proven and Mission-Ready

ESI Motion hardware is not theoretical—it’s flying. Our flight-proven satellite technologies support real-world missions, including advanced satellite servicing, on-orbit robotics, and precision spacecraft mechanisms where reliability is non-negotiable.

With each mission, we continue to refine our space-rated motion and power solutions, ensuring customers benefit from real flight heritage and proven performance.

Enabling the Next Generation of Space

As the commercial and government space sectors accelerate, ESI Motion remains focused on enabling future satellite technologies, sustainable space operations, and high-reliability spacecraft systems.

No matter the orbit, mission profile, or application, ESI Motion is here for your satellite mission—delivering space-rated motion control, satellite battery systems, and power electronics that help spacecraft succeed.
