The broadcast ephemeris is decoded by all GPS [Global Positioning System] receivers. It contains information that allow the GPS receivers to compute the Earth-Centered Earth-Fixed (ECEF) coordinates of each of the satellites relative to the WGS84 datum. The Keplerian elements consist of positional information at a single reference time, and parameters related to the predicted rate of change in order to account for solar radiation and gravity perturbations. Periodic terms are added for argument of perigee, geocentric distance and inclination. The broadcast ephemeris is transmitted daily to the satellites via the Control Segment for future rebroadcast by the satellites. 4, record 1, English, - broadcast%20ephemeris
