# GPS Aiding Almanach Input/Output Message
#
# This message is provided considered obsolete, please use AID-ALM instead!
# - If the WEEK Value is 0, DWRD0 to DWRD7 are not sent as the almanach is not available
#   for the given SV. This may happen even if NAV-SVINFO and RXM-SVSI are indicating
#   almanac availability as the internal data may not represent the content of an original
#   broadcast almanac (or only parts thereof).
# - DWORD0 to DWORD7 contain the 8 words following the Hand-Over Word ( HOW )
#   from the GPS navigation message, either pages 1 to 24 of sub-frame 5 or pages 2 to 10
#   of subframe 4. See IS-GPS-200 for a full description of the contents of the Almanac
#   pages.
# - In DWORD0 to DWORD7, 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.
# - Example: Parameter e (Eccentricity) from Almanach Subframe 4/5, Word 3, Bits 69-84
#   within the subframe can be found in DWRD0, Bits 15-0 whereas Bit 0 is the LSB.
