== Data Formats ==

The ''Format'' field describes the generic type, the '' Format Details'' field specifies individual data sets (separated by comma) and also data rate (in round brackets). Examples:

||=Format=||=Format Details=||=Comment=||
|| RAW || RT17 || Trimble realtime streaming format ||
|| RTCM 3.0 || 1004(1),1008(10),... || RTCM3 data streaming with data specification ||

== Carrier ==

This data field is only useful for data streams containing GNSS measurements or corrections.

Values need update for newer GNSS systems.

||=Carrier=||=Comment=||
|| 0 || No phase information included ||
|| 1 || L1 phase included ||
|| 2 || L2 phase included ||

== Navigations System ==
