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.

WebNov 3, 2015 · 2 Answers. You are right that it should not be considered an inertial frame for many types of problems. This is how you end up with fictitious forces to account for (such as the Coriolis effect). However, this only has practical effect for larger scale problems. For the types of problems generally considered in physics class, the inertial frame ... WebAug 23, 2024 · Inertial Frames of Reference. As you may know, to Aristotle the Earth was the center of the universe. Heavy objects naturally fell towards the Earth and light objects naturally rose away from it.
