For tilt compensated compass instance, here is a standard MPU-6050. If we put it down flat on a table, and take measurements, we will see that neither X, Y or Z (pink, inexperienced, blue) are at zero. Though its not moving! That’s the zero offset. On this case, its about -0.43 for X, 0.32 for Y and 0.34 for Z.

FOG2000 FOG Fiber Optic Gyro features quick startup time, small size, light weight, large bandwidth, low energy consumption, competitive price and wonderful magnetic shielding advantages. FOG2000 FOG Fiber Optic Gyro adopts advanced built-in optics and closed-loop Digital Signal Processing (DSP), which has been extensively utilized in angle control, inertial navigation and built-in navigation, etc.

The path of the Earth’s magnetic field incorporates a horizontal element as well as a vertical component and is often described using the magnetic inclination and declination angles. Magnetic inclination describes the angle between the Earth’s magnetic field lines and a horizontal aircraft. On the Earth’s magnetic poles the magnetic discipline is vertical and has an inclination angle of ninety °, whereas the Earth’s magnetic discipline is horizontal on the equator and has an inclination angle of zero °. The magnetic declination is used to account for the truth that the magnetic North Pole of the Earth isn’t in the same location as True North or the geographic North Pole of the Earth and is characterized as the angle between these two locations, relative to the purpose of measurement.

The HRG is a key ingredient in Northrop Grumman’s Scalable Space Inertial Reference Unit (SSIRU™), a navigation system providing pointing/stabilization and perspective management. Due to its quartz construction, the HRG is inherently radiation hardened and impervious to aging results-making it superb for lengthy missions lasting more than 15 years. Its small measurement additionally means it may be featured in a number of spacecraft designs.
