This chapter describes all sensors and navigation system performance specifications.

Note

Performance specifications are specified in RMS unless otherwise stated.

Inertial Measurement Unit specifications

Quanta Micro integrates a MEMS based tactical grade Inertial Measurement Unit (IMU). Designed by SBG Systems, this IMU benefits from a full temperature range compensation to ensure optimal performance in all applications. The IMU also delivers a consistent performance in challenging vibration conditions.

Navigation & orientation performance specifications

UAV performance

Typical performance in UAV flight conditions with a good GNSS reception.

Heading performance may depend on dynamic conditions (single antenna), or on baseline for dual antenna.
