How to understand the motion of n coordinate frame?

[qingyangG]

In my opinion, once the navigation frame is created, its relative pose to earth frame is fixed. So, how to understand w_en or q_n(k)^n(k-1). Maybe thery are equal to 0 or quternion(I)

The origin point is the position of the carrier, which the navigation result describes. As the carrier is moving, the n-frame is changing.
