SNR
SNR (Signal-to-noise ratio) of GPS Fix, higher is better (>37 is good)
Each compressed message is 26 bytes in size, with an additional 11 bytes added for each
additional “stacked” position.
ASCII Position (Type P)
In ASCII position format, only the most recent fix is sent at each interval, therefore it is most
efficient to have GPS and Iridium intervals equal. This message also appears as it is shown below
in XeosOnline.
P-type messages are approximately 39 bytes, but can be larger if Watch Circle is enabled:
The message type used can be changed using the
$msgenable
command.
