Estimates accelerometer noise. This estimator takes a given number of accelerometer measurements during a given duration of time to estimate accelerometer measurements average, standard deviation and variance, as well as average time interval between measurements. To be able to measure accelerometer noise, device should remain static so that average accelerometer measurements are constant and their standard deviations reflect actual sensor noise. This estimator converts sensor measurements from device ENU coordinates to local plane NED coordinates. Thus, all values referring to a given x-y-z coordinates refers to local plane NED system of coordinates.
Estimates accelerometer norm. This estimator takes a given number of measurements during a given duration of time to estimate accelerometer norm average, standard deviation and variance, as well as average time interval between measurements. For best accuracy of estimated results, device should remain static while data is being collected. In such case, average accelerometer norm should match gravity norm at current location.
Estimates the accumulated mean value of a measurement. This estimator takes a given number of measurement magnitudes (acceleration norm, gravity norm, angular speed norm, magnetic field norm, etc) during a given duration of time to estimate measurement norm average, standard deviation and variance, as well as average time interval between measurements. For best accuracy of estimated results, device should remain static while data is being collected.
Estimates the accumulated mean values of a triad of measurements. This estimator takes a given number of measurement triads (acceleration, angular speed, magnetic field, etc) during a given duration of time to estimate measurement averages, standard deviations, variances, as well as average time interval between measurements. For best accuracy of estimated results, device should remain static while data is being collected. This estimator converts sensor measurements from device ENU coordinates to local plane NED coordinates. Thus, all values referring to a given x-y-z coordinates refers to local plane NED system of coordinates.
Base implementation containing common logic for all estimators.
Estimates gravity norm. This estimator takes a given number of measurements during a given duration of time to estimate gravity norm average, standard deviation and variance, as well as average time interval between measurements. For best accuracy of estimated results, device should remain static while data is being collected.
Estimates gyroscope noise. This estimator takes a given number of gyroscope measurements during a given duration of time to estimate gyroscope measurements average, standard deviation and variance, as well as average time interval between measurements. To be able to measure gyroscope noise, device should remain static so that average gyroscope measurements are constant and their standard deviations reflect actual sensor noise, otherwise only norm values will be reliable. This estimator converts sensor measurements from device ENU coordinates to local plane NED coordinates. Thus, all values referring to a given x-y-z coordinates refers to local plane NED system of coordinates.
Estimates gyroscope measurement norm. This estimator takes a given number of gyroscope measurements during a given duration of time to estimate gyroscope norm average, standard deviation and variance, as well as average time interval between measurements. For best accuracy of estimated results, device should remain static while data is being collected. In such case, average gyroscope norm should match expected Earth rotation rate.
Estimates magnetometer noise. This estimator takes a given number of magnetometer measurements during a given duration of time to estimate magnetometer measurements average, standard deviation and variance, as well as average time interval between measurements. To be able to measure magnetometer noise, device should remain static so that average magnetometer measurements are constant and their standard deviation reflect actual sensor noise, otherwise only norm values will be reliable. This estimator converts sensor measurements from device ENU coordinates to local plane NED coordinates. Thus, all values referring to a given x-y-z coordinates refers to local plane NED system of coordinates.
Estimates magnetometer measurement norm. This estimator takes a given number of magnetometer measurements during a given duration of time to estimate magnetometer norm average, standard deviation and variance, as well as average time interval between measurements. For best accuracy of estimated results, device should remain static while data is being collected. In such case, average magnetometer norm should match expected Earth magnetic flux density magnitude at current location and timestamp.
