About
The PG400 gyroscope is a flight-proven, high-performance standalone unit specifically engineered for CubeSat and SmallSat applications. It provides a plug-and-play solution for satellite attitude determination, optimized for maximum on-orbit stability while demanding low power. The device features an Angular Random Walk of 0.23 deg/sqrt(Hz) and a bias instability of 1 deg/hr. It utilizes an RS422 interface with a request-based protocol for command and data handling, ensuring seamless integration with various platform designs. This compact, precision-engineered gyroscope is suitable for attitude determination across a range of applications, including communications and earth observation. The PG400’s design benefits from the heritage of AAC Clyde Space’s iADCS solutions and is compatible with the iADCS 200 and 400 Attitude Determination & Control Systems. It operates on the unified AAC Hyperion Protocol, simplifying driver development. The gyroscope has successfully flown on orbit since 2023 and is based on the internal IMU design used in the flight-proven iADCS solutions. It has a TRL of 9, a lead time of 16 weeks, and is designed for 5 years in LEO. The unit has been radiation tested up to 50 kRad TID.
