and phases; however, with a float solution, the phase ambiguity is
not a fixed integer number and the “float” estimate is used
instead.
• RTK fixed – where the Rover receiver computes current relative
coordinates, with ambiguity fixing, in differential mode.
The LQ field reflects the status of the received differential messages
and contains the following information:
• Data link quality in percentage
• Time (in seconds) elapsed since the last received message
• Total number of received correct messages (dependent on the
message type received)
• Total number of received corrupt messages (dependent on the
message type received)
If the receiver is not (for some reason) receiving differential
corrections, or if none of the ports have been configured to receive
differential corrections, the LQ field is either be empty or looks like
this: 100% (999,0000,0000).
