Serenum Space, a Czech-based CubeSat subsystem manufacturer and service provider, is setting new benchmarks in the small satellite sector through a suite of advanced space technologies and customizable nanosatellite platforms. As a commercially oriented subsidiary of the Czech Aerospace Research Center, Serenum brings decades of aerospace expertise into modern, affordable, and flight-proven solutions for CubeSat developers worldwide. From mission-critical ADCS systems to fully integrated satellite buses, Serenum is helping academic, commercial, and government teams realize reliable access to space.
Technology and Innovation
Serenum Space is focused on designing and delivering highly modular, space-qualified subsystems for CubeSats, with a particular emphasis on reliability, compactness, and system-level integration. One of the company’s signature technological offerings is its VAC02 ADCS (Attitude Determination and Control System), a plug-and-play solution that combines multiple flight-proven technologies into a compact 1U/3U-compatible module. The system integrates reaction wheels, magnetorquers, a magnetometer, a gyroscope, and a sun sensor, all managed by an ARM Cortex-M7 processor, offering advanced onboard processing capabilities.
What makes the VAC02 ADCS distinctive is its support for multiple operational modes, including inertial pointing, nadir pointing, sun tracking, and LLA (latitude, longitude, altitude) target tracking, allowing CubeSats to achieve autonomous, mission-specific orientation in orbit. It offers pointing precision as fine as 0.15° (relative) and radiation tolerance up to 36 krad, ensuring durability even in high-radiation environments like sun-synchronous orbits. The system is built to meet CubeSat Space Protocol (CSP) standards and supports CAN, I²C, and UART interfaces, ensuring seamless integration with a variety of onboard systems.
Serenum Space emphasizes platform-level modularity through products like the V-Bus 3U, a satellite bus that incorporates flight-proven subsystems, including redundant data storage, robust power systems, and mechanical support for 1U payloads. This platform is tailored for precision-pointing missions and is designed with thermal, electrical, and structural interfaces optimized for rapid mission integration. By combining space heritage with modular hardware, Serenum enables customers to deploy and scale CubeSat missions with reduced development risk and lead times.
Products and Services
Serenum Space offers a broad range of subsystems, mechanical tools, and satellite infrastructure designed to meet the diverse needs of space missions. These products are engineered for reliability, integration flexibility, and performance in low Earth orbit environments. The VAC02 ADCS provides a compact, high-performance attitude control system for CubeSats. It supports multiple control modes including inertial, sun-pointing, and nadir-pointing, and includes components like reaction wheels, magnetometers, and sun sensors. Its robust architecture ensures accurate attitude determination even in high-radiation environments. Serenum manufactures custom mechanical jigs and fixtures for CubeSat assembly and integration workflows. These JIGs help ensure mechanical alignment, reduce build errors, and provide structural support during system validation. They are vital tools for satellite developers during pre-launch operations and subsystem testing.
Log detectors developed by Serenum are designed to measure RF signal strength across wide dynamic ranges. These devices are essential in communication payloads or RF characterization during system testing, offering reliable performance in space-qualified environments. Integrated into their ADCS offerings or available as standalone units, Serenum’s reaction wheels offer high-torque, low-noise attitude actuation. These are built with compact form factors and precision balance, supporting agile spacecraft maneuvering and stabilization without relying on propellant-based systems.
The V-Bus 3U platform provides a ready-to-integrate structure with onboard power distribution, data handling, and control systems. It accommodates a 1U payload volume and supports redundant storage, stable voltage rails, and precise pointing capability. To ensure safe transit of valuable satellite hardware, Serenum offers specialized transport enclosures designed to shield satellites from shock, vibration, and environmental contamination. These transport boxes are custom-built for CubeSat configurations and facilitate secure shipping to launch integration facilities. Serenum’s sun sensors are used for real-time solar positioning and are integrated into various spacecraft orientation systems. With precise angle detection, they enable accurate sun-tracking capabilities, essential for attitude control, solar panel orientation, and thermal management in orbit.
In December 2024, Serenum Space announced a strategic cooperation with Wittenstein, a leader in precision mechatronics, hinting at upcoming enhancements in reaction wheel and motor technologies for microspacecraft. Additionally, Serenum played a key role in the PROBA-3 launch, contributing subsystem support for ESA’s formation-flying technology demonstrator.
Serenum is focused on expanding its service portfolio through Satellite-as-a-Service (SaaS) models, enabling clients to outsource in hardware and entire CubeSat missions, from hardware integration and qualification to launch and operations support. The company is also enhancing its qualification and acceptance testing services to better support customers during pre-launch verification phases, including vibration, thermal vacuum and EMC testing.
Serenum is expected to roll out new miniaturized subsystems, improved data interfaces, and enhanced platform modularity for higher payload flexibility. With strong ties to the Czech Aerospace Research Center, the company remains positioned to commercialize advanced aerospace research into practical, flight-ready solutions for a growing global space economy.
