| PlanarGyroParams (double arw, double biasInstability) | |
| double | arwSigma (double deltaT) |
| Std dev of the integrated measurement (rad), for the specified duration (sec). | |
| double | biasInstabilitySigma () |
| Bias instability is the "zero slope" part of the Allan curve, so it is not dependent on sample rate. | |

| double gtsam::PlanarGyroParams::arwSigma | ( | double | deltaT | ) |
Std dev of the integrated measurement (rad), for the specified duration (sec).
Integrated gaussian white noise is also gaussian, scaled with duration, so std dev scales with sqrt(time), so the unit here is rad.
| double gtsam::PlanarGyroParams::biasInstabilitySigma | ( | ) |
Bias instability is the "zero slope" part of the Allan curve, so it is not dependent on sample rate.
The unit here is rad/s (same as the unit of bias itself).
