The table below gives average data throughput figures (in
bytes/sec) for different GNSS signals and three message
types (RTCM-3 given as reference).
* Worst-case estimates. Real throughputs are often shorter by 4 to 8 bytes.
NOTE: For more information on the size of ATOM
messages, please refer to the ATOM Reference Manual.
• The ports used to make the differential messages
available to users are defined on the Base Setup page.
To define raw data messages, click on Data Output and then on
the Raw Data submenu. Use the page that opens as explained

then enter its output rate, in seconds, in the Rate field,
and finally click on the Add button. The new message
definition will then appear as a new row in the table on
the right.
– To change the definition of an existing message (port,
rate), select the corresponding row in the table. This
populates the three fields on the left with the
definition of that message. Edit the port and/or rate
