About
The Umbra Magnetometer + Sun Sensor (MSS) Package is a low-size, weight, and power (SWaP) solution for precise attitude determination. The integrated tri-axis magnetometer and dual-axis sun sensor provide essential magnetic field and solar orientation data for small satellite GNC systems, delivering fine dual-axis sun sensor accuracy (<1° at boresight) together with tri-axis magnetometer readings. At less than 65 grams, it is built for demanding missions requiring high-performance attitude knowledge in resource-constrained environments.
