SatBase

This magnetorquer is designed to deliver reliable and efficient magnetic actuation for CubeSat and small satellite attitude control applications. With a nominal dipole moment of 0.3 Am², it provides effective torque authority for detumbling, momentum dumping, and fine attitude adjustments in low Earth orbit missions. The unit features a precision-engineered coil with 8 layers of winding, optimized to achieve a strong magnetic moment while maintaining low power consumption and thermal stability. Operating at a nominal input voltage of 5 V, the magnetorquer is fully compatible with standard small satellite electrical power systems, enabling straightforward integration without additional power conditioning. Its compact and lightweight design supports missions with strict size, weight, and power (SWaP) constraints. The device is suitable for both standalone use and integration within complete Attitude Determination and Control System (ADCS) architectures, including hybrid configurations with reaction wheels. Built with reliability and repeatability in mind, this magnetorquer is ideal for a wide range of missions, from technology demonstration and academic CubeSats to commercial small satellite platforms. Customization options are available to meet specific mission requirements, including mechanical interfaces and electrical characteristics.

The Multi-Head Star Sensor is a unique solution that can integrate up to six sensor heads to significantly increase data availability during large attitude maneuvers. The number and orientation of the heads can be fully customized to mission requirements. Thanks to their ultra-compact design, the sensor heads can easily be integrated into a CubeSat’s tuna can, making them ideal for space-constrained platforms.

The ST400 is the bigger brother of the successful ST200 star tracker. It uses the same proven electronics but uses a different opto-mechanics. The ST400 trades an increased resolution for being a little larger than the miniature ST200. Like ST200, the ST400 has been developed in cooperation with Hyperion Technologies B.V. The ST400 delivers a full and autonomous attitude solution and is your attitude sensing solution for missions with demanding accuracy requirements.
