Both Base and Rover receivers must be configured according to the desired measuring method.
• In applications where real-time positioning results are required, the Base receiver provides
the correction information needed to properly calculate the location of the Rover receiver.
A Base station is normally set up over a known point and collects GPS/GLONASS data
from satellites. As the receiver picks up satellite data, it measures the carrier and code
phases to accurately compute and verify its location. Then, the receiver transmits this
information via radio to the Rover receiver.
• The Rover receiver applies correction information from the Base station to its current
location to accurately calculate one or more points. Rovers are mobile GNSS receivers
that compares the information from the Base station to the data it logs from satellites and
applies correction algorithms to accurately calculate a new point.
• In applications intended for post-processing, the receivers typically log code phase and/or
carrier phase measurements separately from common satellites and during the same time
interval. This data is then processed using post-processing software (for example, Justin).
When configuring receivers for RTK measuring, use the following list to ensure the receivers are
properly set up:
• Perform pre-measuring preparation as described in Chapter 2.
• Configure one receiver as an RTK Base station and the other receiver as an RTK Rover.
See “Configuring the Receiver” on page 51.
• Configure the communication data link for transmitting and receiving corrections. See
“Configuring the GSM module for Point-to-Point radio link” on page 44 and “Configuring
the GSM module for Internet access” on page 46.
• Set up the Base receiver over a known point to begin collecting static observation data and
transmitting corrections. Set up the Rover receiver to begin collecting RTK data. See
“Receiver Setup” on page 65 for more information.
When configuring receivers for post-processing measuring, use the following list to ensure the
receivers are properly set up:
• Perform pre-measuring functions as described in Chapter 2.
