• Code differential – where the Rover receiver computes the current relative coordinate in
differential mode using only pseudo ranges.
• RTK float – where the Rover receiver computes the current relative coordinates in
differential mode using both pseudo ranges 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
has been configured to receive differential corrections, the LQ field will either be empty or it will
look like this: 100%(999,0000,0000).
