Chapter 4 Rtk Survey Preparation; Rtk Parameters; Data Formats - Thales Z-Max Operation And Application Manual

RTK Survey Preparation
The previous two chapters laid the groundwork for understanding the purpose of each
component of the Z-Max RTK System and the relationship between the components.
This understanding of the functionality and connectivity of the RTK system
components will prove invaluable during RTK survey preparation and execution. Let's
put this new found knowledge to good use.
In this chapter, we will present a brief overview of the RTK surveying parameters that
must be chosen during the RTK setup, and then go through the steps required to set
up the base and rover systems to perform an RTK survey.

RTK Parameters

When configuring the receiver to perform an RTK survey, you will have access to
many parameters that affect the survey that is executed. While we have made every
attempt to minimize the parameters that must be changed by setting them to the most
common default values, we will review them and provide some guidance as to what
the choices mean. In addition, there are several issues related to RTK surveying of
which you should be aware that are presented briefly.

Data Formats

From previous discussions, it should now be clear that RTK surveying involves the
transmission of data from the base station to the rover station. The format of the data
that is transferred by the base station and received by the rover is selectable. The Z-
Max base station can be set to transmit in one of three data formats, and the base and
the rover must be set to use the same format. The following is a list and a brief
description of each format.
DBEN: a compressed company-proprietary data format that includes GPS
pseudo-range and carrier phase measurements. This is the default data format.
