Starting Base and Rover Radio RTK  

If you are doing a RTK survey with a base and rover receiver 

using radios, follow the steps outlined below.  If you are using 
an internet GPS service with a cell phone for a modem, or if 

you are using a rover with a radio and the base is already 

setup and broadcasting corrections, follow the steps in the 
Remote Rover section. 

Start Base Receiver  

1.

 

Go to the 

Survey

 > 

Start GPS Survey

 screen.  If you are 

using a serial cable for base and rover, connect the base 

serial cable to the data collector.  If you are using 
Bluetooth for base or rover, tap 

Base

 when prompted for 

the receiver to connect to. 

2.

 

Measure the base antenna height while you wait for the 

base to warm up and verify its position.  Enter the 

Measured

 height and select the correct 

Measure To

 mark 

in the drop down box.  If required, you can also enter the 

base antenna serial number for book keeping. 

Note:  When the base is on a variable height tripod, you 
usually measure a slant height from the setup point to the top 

of the notch on the EPOCH L1/L2 antenna.  If the base 
antenna is on a fixed height tripod, you would enter the fixed 

height and the 

Measure To

 mark would be the bottom of the 

antenna mount.  If the base antenna is on top of the 
EPOCH25 receiver which is on top of a fixed height tripod, 

then you would enter the fixed height and the 

Measure To

 

mark would be the bottom of the EPOCH25 receiver. 

3.

 

When the screen says the base is ready to set, and you 

have the antenna height and measure to mark correctly 
entered, tap 

Next >

. 

Note:  If you have a 

Recording Interval

 set on the Post Process 

card in the job settings, the base receiver will start a static 
post processing file when you start the RTK.
