2. Performance specification
Performance specifications presented in this section may vary from one Quanta configuration to the other.
2.1. Inertial measurement unit
As an IMU is the main component of an inertial navigation system, the Quanta IMU has been carefully designed to
take full advantage and performance of MEMS technology.
2.1.1. Accelerometers
Quanta IMUs embed a set of 3 MEMS capacitive accelerometers that provide a consistent performance in all
conditions, including vibrating environments.
The specifications are listed in the table below, depending on the IMU configuration.
