What is an inertial navigation platform?

Oct 01, 2019

The core component of the inertial navigation platform inertial navigation system, its role is to provide the size and direction of the carrier specific force for the entire inertial system, or to decompose the carrier's specific coordinate system into corresponding corresponding force components, such as The figure shows:

INS (1)

In order to do this, there are two options available. The first is the “striplight approach” and the second is the “platform approach”. In the strap-down mode, the accelerometer is mounted directly on the carrier and measures the specific force along the axis of the coordinate system that is attached to the carrier. In order to know the direction of the coordinate system of each instant relative to the calculated coordinate system, the gyroscope must be mounted on the carrier. Such a gyroscope should be able to measure the rotational angular velocity of the carrier over a large measurement range with high precision.
