Description

Measurements Provided:

geographic position (latitude, longitude, altitude), velocity relative to the Earth, and attitude angles of the aircraft (pitch, roll, heading)

Typical Sampling Rates:

10 Hz

General Description:

An inertial reference unit, providing position, velocity, and attitude information. The unit is coupled to GPS measurements for updating via a Kalman filter, to remove drift and/or mis-alignment. This is a compact unit designed for installation in small spaces, and it is hardened against vibration, so it is often used on RAF aircraft in wing pods. It has been used in conjunction with the Laser Air Motion Sensor (LAMS), a wing-mounted gust system, and for installation in the radome of the C-130. T

Measurement Characteristics:

The manufacturer quotes these specifications:

Position (SEP): 3.9 m
Velocity (1 sigma, horiz/vert): 0.1/0.1 m/s
Pitch and Roll (1 sigma): 1.0 mrad
Timemark Output 1 pps: 1 microsecond
Heading (1 sigma, in motion): 1.5 mrad

Calibration Methods:

The measurements from this unit are normally compared to those from the Honeywell IRUs on the aircraft for validation of the measurements.
