About
The Attitude Control Module PnP ADCS-N1 is a fully integrated, plug-and-play attitude determination and control system (ADCS) for small satellites, combining a complete suite of sensors and actuators in a single module. It includes 2 star trackers (5 arcsec pointing / 50 arcsec rolling accuracy at 3-sigma, 10 Hz update rate, 2 deg/s dynamic range), a sun sensor (0.1 deg accuracy, 10 Hz, 90×90 deg FOV), a gyroscope (0.5 deg/h zero-bias stability, 0.03 deg/sqrt(h) angle random walk, +/-300 deg/s rate range), a magnetometer (+/-8 Gauss range, +/-1.0% FS linearity error, 10 nT field error), 4 reaction flywheels (20 mNms max angular momentum, 2.5 mNm max torque, 1 rpm speed control accuracy), 3 magnetic torquers (0.82 A*m2 at 12V / 0.34 A*m2 at 5V max magnetic moment), and a GNSS receiver (<=10 m position resolution, <=0.1 m/s velocity accuracy). By packaging attitude sensing, control actuation, and navigation into a single plug-and-play module, the ADCS-N1 simplifies satellite bus integration and provides full 3-axis attitude determination and control capability for small satellite/CubeSat missions.
