About
NanoTorque GSW-600 consists of four compact and high-performance reaction wheels, each designed and qualified for an equivalent of 5 years in-orbit operations. The product is delivered in a 4-wheel pyramid setup within a mounting bracket, optimized for three-axis attitude control of CubeSats. The compact envelope allows all four wheels to be installed in a redundant pyramid configuration within the standard CubeSat form factor. NanoTorque GSW-600 is designed for seamless integration with the NanoTorque GST-600 3-axis magnetorquer; together they form GomSpace’s complete attitude determination and control solution for nanosatellites, enabling reliable mission operations for LEO commercial and scientific applications.
