# GPS Aiding Ephemeris Input/Output Message
#
# This message is provided considered obsolete, please use AID-EPH instead!
# - SF1D0 to SF3D7 is only sent if ephemeris is available for this SV. If not,
# the payload may be reduced to 8 Bytes, or all bytes are set to zero,
# indicating that this SV Number does not have valid ephemeris for the moment.
# - SF1D0 to SF3D7 contain the 24 words following the Hand-Over Word ( HOW )
# from the GPS navigation message, subframes 1 to 3. See IS-GPS-200 for a
# full description of the contents of the Subframes.
# - In SF1D0 to SF3D7, the parity bits have been removed, and the 24 bits of
# data are located in Bits 0 to 23. Bits 24 to 31 shall be ignored.
