WebECEF stands for Earth-Centered Earth-Fixed and specifies coordinates that are (a) measured from the Earth’s center but (b) which rotate with the Earth instead of staying fixed in space. An example would be the latitude and longitude of the Lowell Observatory, which stays in place on the Earth’s surface but from the point of view of the rest ...

X runs through the equator at the prime meridian (latitude = 0, longitude = 0). Y passes through the equator 90 degrees east of the prime meridian (latitude = 0, longitude = 90 degrees).
WebSatellite positions are initially calculated at the transmission time in “the ECEF frame at transmission time” and not at the ECEF frame at the time of receiving the signal. According to [ 24 ], this time difference is approximately in the range of 70–90 milliseconds, during which the Earth and the ECEF rotate, and this can cause a range ...
