The initial epoch is usually chosen as the first epoch when both GNSS and INS data are available. The INS epoch closest to the GNSS epoch must be used because the sampling rates differ.

WebFor most state vectors, this is the Earth-Centered Inertial (ECI) coordinate system. The first part of this designation should seem fairly obvious. That is, since we're studying objects that revolve around the center of the Earth, it seems natural to have the center (origin) of our coordinate system at the center of the Earth.
