TOPCON Hiper Ga with FC-2000

GPS RTK (NTRIP) SURVEY PROCEDURE GUIDE

Introduction:

Real Time Kinematic surveying used for topographic survey and
stakeout, and is the most precise method of Real Time surveying.
Network Reference Stations allows us to eliminate/reduce systematic errors in reference
station data,

wider areas.
by eliminating the need to set up a base station.

to provide high-accuracy, real-time kinematic (RTK) GNSS positioning for

A VRS network improves productivity while at the same time reduces costs,

The purpose of this guide is to provide a step-by-step procedure for
completing RTK topographic surveys using the Topcon hardware and software. This
guide consists of following sections:

Initial Setup
Topography Surveying
Importing Job
Exporting Job
Localization

Hardware Required:

Topcon Hiper Ga Dual-frequency receiver
Topcon Controller FC-2000 with Bluetooth Card (Data Collector)
Mobile with SIM Card

Software Required:

TopSurv running in Windows CE operating system (on FC-2000)
Top Link software for PC (Download)

The Radio Link should be 100% and the RTK­age should be 0 or 1sec. This means the radio
is communicating the base station information
to the rover receiver. If either of these values
is something different, the “Positioning Type”

Localization:

Localization is used for transforming coordinates between local system
and a WGS84 system. The more points used, the more precise the localization.
Localization is performed on a site where you wish to work with the existing local
coordinate system. To ensure an accurate localization you need at least 4 known points.

Select a position for your base that will give the best radio range for
your project. This may be a known point or you may wish to create a new station a more
suitable location. This point does not need to be part of your current survey network.
Setup the base over the point, connect with controller and start base and after that connect
rover. Localization file should be keep separately.
