The geodetic coordinates displayed on the Geo tab are
always computed in WGS84 and have four solution
types.
• Standalone – where receiver computes 3D
coordinates in autonomous mode without using
differential corrections.
• 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
• Total number of received corrupt messages
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).
