WebDec 15, 2024 · Since the entire ECEF reference frame rotates with the earth, this coordinate system is useful for positioning geo-stationary objects such as satellites. In fact, the Global Positioning System (GPS) uses ECEF as it’s primary coordinate system and derives all other coordinates from it. However, since ECEF has an origin that is very far … WebThe particle has a lifetime (τ) in its own reference frame, but from the Earth's reference frame, it will experience time dilation. This means that the particle's lifetime as observed by an observer on Earth (t) will be longer than τ: t = γτ where γ …
