Comments
• For each of the SNV, SNG, SNW, SAL, SAG, SAW and ION
messages, the f4 parameter can only take an integer value
of seconds and refers to the interval between messages
related to the same satellite and with the same content.
For a given satellite, each of these messages is therefore
renewed every x seconds (where x=f4), or following a
change in the message content (“on change”), whichever
occurs first.
Each of these messages cannot be output more than once
over a given period of 1 second.
• By default, f4 is set as follows:
• The SBD message output rate is always 1 second (as
decoded). Parameter f4 is ignored.
