(http://gazebosim.org/wiki/Sensor_noise):
rates (rad/s): mean=0, stddev=2e-4
accels (m/s/s): mean=0, stddev=1.7e-2
rate bias (rad/s): 5e-6 - 1e-5
accel bias (m/s/s): 1e-1
Experimentally, simulation provide rates with noise of
about 1e-3 rad/s and accels with noise of about 1e-1 m/s/s.
So we don't expect to see the noise unless number of inner iterations
are increased.
We will add bias. In this model, bias is sampled once for rates
and once for accels at startup; the sign (negative or positive)
of each bias is then switched with equal probability. Thereafter,
the biases are fixed additive offsets. We choose
bias means and stddevs to produce biases close to the provided
data. -->
