ImuModel navtk::filtering::hg1700_model()

Returns the Honeywell HG1700 IMU model.

There are a number of HG1700 models, these specs are for the higher-end versions. Bias tau values are assumed. Scale not present in sheet and are set to 0.

See https://prod-edam.honeywell.com/content/dam/honeywell-edam/aero/en-us/products/navigation-and-sensors/inertial-measurement-units/hg1700-inertial-measurement-unit/documents/hon-aero-n61-1619-000-001-hg1700-inertial-measurement-unit-brochure-en.pdf?download=false

Spec sheet values given as (all 1 sigma):

Accel Bias: 1 mg = 9.81e-3 m/s^2

VRW: 0.065 fps/sqrt(hr) max = 3.302e-4 m/s^(3/2)

Gyro bias: 1 deg/hr = 4.8481e-6 rad/s

ARW: 0.125 deg/sqrt(hr) max = 3.6361e-5 rad/s^(1/2).

Conversions assume gravity value of 9.81 m/s^2.

Returns

The error characteristics of on an HG1700 IMU.
