calculation. You may select between the Clarke 1866 ellipsoid and the WGS84 ellipsoid.
New Zealand:

You may select between “NZGD2000” and “NZGD49”. Both use the Transverse Mercator

calculation. NZGD2000 uses the GRS80 ellipsoid. NZGD49 uses the International 1924 ellipsoid. You may

specify a Meridional Circuit with either datum. To select the circuit, press the Define button. You will see a

pull-down list with all Meridional Circuits as well as the option to pick None.
RGF 93 (France):

This system requires that you have the file named “Predef1.csl” in the SurvStar directory

on the data collector. If this file is not found, please re-install FAST Survey.
NTF (France):

This system requires that you have the file named “Predef1.csl” in the SurvStar directory on

the data collector. If this file is not found, please re-install FAST Survey. NTF is an approximation of the

NTF-GR3DF97A grid transformation.
NTF-GR3DF97A:

This system is a grid transformation that requires the files “Predef1.csl” and

“gr3df97a.bin” to be in the SurvStar directory on the data collector. The “Predef1.csl” file is part of the default

installation. You will need to use Data Transfer to copy the “gr3df97a.bin” file from your CD to your data

collector.
OSTN02 (UK):

This system is a grid transformation that requires the files “Predef1.csl”, “ostn02_x.bin” and

“ostn02_y.bin”. The “Predef1.csl” file is part of the default installation. You will need to use Data Transfer

to copy the “ostn02_x.bin” and “ostn02_y.bin” files from your CD to your data collector.
RD2000:

This is the RD NAP transformation for the Netherlands. This system is a grid transformation that

requires the file “Predef1.csl”, “X2C.grd” and “Y2C.grd”. The “Predef1.csl” file is part of the default

installation. You will need to use Data Transfer to copy the “X2C.grd” and “Y2C.grd” files from your CD to

your data collector.
Denmark 34:

Used for all cadastral mapping and for most technical mapping carried out in Denmark. System

34 is a two dimensional - horizontal - coordinate system. System 34 is based on the National Geodetic

Reference Network and is divided into two different zones, one covering Jutland and Fuen, and the other

covering Sealand. The island of Bornholm has its own coordinate system called System 45.

Add User Defined:

To define a new coordinate system, go to the Localization under the EQUIP tab. You will find

the Edit Projection List button under the SYSTEM tab. Then select the Add User Defined button. Enter a name

for your system (e.g. PRVI for Puerto Rico/Virgin Islands), then select a projection (in the example below,

Lambert_Conformal_Conic_2SP) and enter the appropriate parameters. Note that all latitude and longitude values

are in decimal degrees and False Northing and False Easting are always presented in meters. All entries involving

degree must be in decimal degrees based on a 360 circle.

New Datum:

You may select a predefined Ellipsoid or set your own parameters by typing in a new ellipsoid

name and entering values for a and 1/f. The values for dX, dY, dZ, rot X, rot Y, rot Z and scale are “to

WGS84”.
