The XACT-15 from Blue Canyon Technologies is an ADCS System that is designed to provide high accuracy and precision attitude control for CubeSats. This ADCS system has momentum storage of 15 mNms and a maximum torque of 0.005 Nm. It has a slew rate of up to 10 deg/sec (4kg, 3U CubeSat) and a pointing accuracy of ±10.8 arcsec for 2 axes (±25.2 arcsec for 3rd axis). The ADCS system has a lifetime of up to 5 years in low-earth orbit with a radiation tolerance of greater than 40 Krad. It supports the RS-422 interface and requires a DC supply of 12 V. The XACT-15 system includes a star tracker, reaction wheels, torque rods, and coarse sun sensors. It also features user-friendly software that supports simulation, integration, and customization. It has a mass of 1.1 Kg and measures 10 x 10 x 5 cm.
