VAC02 ADCS

Availability: 24 weeks

Features

VAC02 is a plug-and-play, fully integrated, versatile Attitude Determination and Control System (ADCS) solution designed for CubeSats with 1U to 6U form factors. It is equipped with three reaction wheels, three magnetorquers as actuators, six sun sensors, plus two magnetometers, and three gyroscopes as sensors. This compact solution with Cortex-M7 computer provides exceptional pointing awareness and performance for smaller CubeSats. VAC02 can be also modified to handle larger form factors (up to 16U).

Properties

The properties depend on the reaction wheels used. Two options are available: RW25 from SERENUM SPACE or cyber® reaction wheel 2 by WITTENSTEIN.
