Gyroscopes: Likely comes with the IMUs so whoever is looking into those might want to look into these too

• IMU typically consists of gyroscopes which are inertial sensors that measure angular rate with respect to an inertial reference frame

For reference this is the basis of a gyroscope.:

The different types of Gyroscopes are:

• Laser Ring Gyro(RLG):
  • The advantage of using an RLG is that there are no moving parts. Compared to the conventional spinning gyro, this means there is no friction, which in turn means there will be no inherent drift terms. Lightweight properties, compact and small, and high durability.
• Hemispherical Resonator Gyros:
  • 14- 15 year lifespan with high-reliability
  • The downside is that there are high-temperature drifts. Must be kept in a chamber.

• Microelectromechanical system (MEMS) gyros:
  • Compact and small, lightweight, low power consumption, low cost,

IMUs (Inertial Measurement Unit): Measures and reports the satellite's specific force, angular rate, and orientation.

Components:

• 3-axis accelerometer → measures specific force/acceleration
• 3-axis gyroscope → measures angular rate
• 3-axis magnetometer (optional) → measures magnetic field surrounding system

Performance Grades:

There are different types of IMU Sensors:

• FOG (fiber optic gyroscope)
  • All grades
• RLG (ring laser gyroscope)
  • Tactical and navigation grades
• MEMS (micro-electro-mechanical systems)
  • Typically for consumer, industrial, tactical grades
