Precise Ephemeris Center of Mass and Antenna Phase Center UPDATE Notice!!!
Starting with GPS Week 1769 (01 December 2013) the precise ephemeris, both Center of Mass and Antenna Phase Center, will be produced using an Updated EPOCHA Kalman process. This change will be 'invisible' to the user and the output data will remain in the SP3 format.
Also, we will be transitioning from a 16-bit to a 32-bit file compression algorthym for our data storage.
