• Baud rate drop-down list – select a baud rate (i.e., the receiver port baud rate at
which differential messages will be received from modem).
Tip:
Pacific Crest PDL (UHF) modems, use a 38400 baud
rate.

7. Click Apply .
8. Click OK to close the Receiver Configuration screen.
9. On the main screen, check the LQ field to ensure the receiver obtains differential
corrections. Usually, the receiver will start to output the coordinates of the antenna's
phase center along with the solution type within 10-30 seconds.
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
