RTK Application
RTK is a technique for increasing GNSS positioning accuracy. It involves the use of one stationary
reference receiver, called the base station, that sends correction data to one moving receiver, called the
rover. The correction data source can either be a:
⚫
local fixed base station; or
⚫
third party correction service
This chapter outlines how the LG69T (AM) module is used as the rover and LG69T (AS) module is used
as the base station, as well as how to:
⚫
Connect to the base station,
⚫
Configure the base station,
⚫
Configure RTK data interaction mode, and
⚫
Configure STRSVR tool.
7.1.
Connect to Base Station
LG69T (AS) module is the base station that provides correction data required by the rover to enter RTK
mode. The transmission of such data from the base station to the rover is carried out via NTRIP or TCP
protocol with STRSVR tool over the Internet. Users need to keep delays to a minimum when transmitting
the data.
