Then you haven't found the Ephemeris Report Packet 0x58 type 6 where Byte 4 is the SV number. The text is fuzzy, but if you consider that Byte 2 in the common header to all 0x58 replies contains the PRN number, it is more likely to be a documentation miss than anything. It would be a simple matter to verify this by simply requesting this message for all PRNs and then check byte 4.
