Once the hardware and software are successfully communicating, the status window will display
"Ready" in blue.
The status window is always shown in the software. From left to right, it indicates date and time from
the computer's clock, event log, GPS fix quality indicator, and position and IMU information.
GPS fix information is parsed out of the NMEA string. The first number displayed is the GPS quality.
Status of 2 indicates GPS position without RTK correction. Status of 4 indicates GPS position with RTK
correction. When GPS status 4 (RTK) is being collected a picture of a satellite will appear. The second
number is number of satellites used. Clicking on the GPS status window will display the entire NMEA
string that is being read by the software.
Example of GPS information with no RTK
information.
