What is the definition of range?
For navigation systems, range is the minimum and maximum input value limits that the sensor can measure. Any input outside these limits cannot be accurately measured and, therefore, will not produce any output from the sensor.
The range for accelerometers is defined as g-units (1 g = -9.8 m/s2); magnetometers are defined using G-ratings (“gauss”), and for gyroscopes (angular rate sensors) in °/s.
