What is the rate noise density of gyroscope?(a) 0.011 dps/√Hz(b) 0.0011 dps/√Hz(c) 1.11 dps/√Hz(d) 11.1 dps/√HzThis question was addressed to me in unit test.Query is from Accelerometer and Gyroscope Sensor in portion Sensors of IOT

Answer»

The correct option is (a) 0.011 dps/√Hz

To explain I would say: GYROSCOPES offer SUPERIOR STABILITY over time and temperature, with a rate noise DENSITY up to 0.011 dps/√Hz. This guarantees the level of accuracy REQUIRED by the most of the advanced motion-based applications.
