1. For multiple command actions, the bits in W1 may be OR’ed.
2. Words W9 through W32 contain the 24 bytes of packed GPS navigation
message data corresponding to data-words 3 through 10 (without parity) of the
specified page and subframe.
3. Entire message will be repeated 35 times, once for each of the
pages/subframes containing pertinent almanac entries. Almanac data
subframes for SV PRNs 1 - 32 will be sent first, in that order. The final 3
messages will consist of those pages/subframes containing ionosphere and
UTC parameters, AS flags, SV configuration and SV health; the order will be
Page18/Subframe4, Page25/Subframe4, and Page25/Subframe5.
4. Use ACK/NAK (W1, B2) messaging to maintain integrity of the full almanac
set.
5. Block cannot be set to output based on trigger or by data rate. Only ‘on
change’, ‘by SV’, and ‘NOW’ can be requested.
