positional accuracy. Check the RTK SOLUTION LED to verify that the
LED is blinking green.
Continue to travel the traverse until the entire course has been observed. You can
now return to the office and download the data.
If during the survey, the RTK SOLUTION LED blinks YELLOW, wait until the receiver
re- initializes and the LED blinks green again before occupying a point. If the LED
does not become green again, you will have to troubleshoot the system to determine
the problem. See Chapter 6 - Troubleshooting for more information about
troubleshooting your system.
MANUAL RTK SURVEYS
In Manual surveys, there are no special parameters to set. The Site ID is manually
entered and you can collect data on any point for as long as you wish. Data is
collected until you manually instruct the receiver to stop.
Manual RTK Set Up
1. Verify the SURVCONF menu is in RTK ROVER mode.
From the SURVCONF menu, use the UP/DOWN control keys until the
MODE is displayed. Verify that the mode is MODE:RTK ROVER. If it is
not, press the ENTER key and select RTK ROVER.
2. Set the positioning algorithm.
From the SURVCONF menu, access the POSITIONING submenu. Select
the desired RTK positioning algorithm. COARSE will output Fast RTK
positions. FINE will output synchronized RTK positions. Either type is
acceptable. The default is COARSE. To change this parameter, press the
ENTER key and select the desired algorithm.
3. Set the recording interval.
From the SURVCONF menu, use the UP/DOWN control keys until the
REC INI submenu is displayed. The recording interval will determine the
output frequency of the RTK positions. The range is dependent upon the
firmware options enabled in your receiver, the output frequency of the
base station data and the positioning algorithm selected in step 2. In
general, the recording interval should be set to a value or 1 second or
less.
Manual RTK Survey Execution
1. At the first point to be surveyed, set and level the survey pole on the point.
Verify that the RTK SOLUTION LED is blinking green.
2. Enter the antenna height.
Access the SURVEY:RTK ROVER submenu and use the UP/DOWN
