Introduction
The purpose of this short manual is
to give guidelines and useful hints on
how to perform static, rapid static and
kinematic surveys using SR510,
SR520 or SR530 GPS receivers
without utilizing Realtime techniques.
Realtime applications, based on the
use of radio modems - in particular
RTK (Real-Time-Kinematic) opera-
tion with SR530 receivers - are
described in the booklet "Getting
Started with Real-Time Surveys".
Full description of all features and
functions of System 500 can be
found in the "Technical Reference"
Manual which is available as an
electronic PDF document only. This
manual can be found on the SKI-Pro
installation CD. For more information
please refer to the file
\MANUALS\README.TXT on the
SKI-Pro installation CD.
It is assumed that the reader of this
manual is familiar with the principles
of GPS Surveying, i.e. he knows the
concept of differential measure-
ments, the need for a reference
receiver, etc. A basic introduction of
these principles is given in the
booklet "General Guide to Static and
Rapid Static".
After studying these guidelines a user
will know the basic concepts and
principles of how to operate System
500 and carry out static, rapid static
and kinematic GPS surveys.

Equipment checklist for Static and Rapid-Static measurements using System 500
Batteries are needed to power the
sensor. Standard are two camcorder
batteries which are plugged into the
backside of the sensor and power the
unit for about 6 hours.
Warning
Brand new camcorder
batteries need about 5
charging cycles before
reaching the full capacity. It is
highly recommended to fully
charge and decharge
camcorder batteries for 4 to 5
times before start-ing using
them for practical fieldwork.
This is easily accomplished
by plugging them into the
sensor and having the sensor
turned on until the sensor
switches off automatically
once the batteries get flat.
Then simply recharge them
and repeat this exercise.
Equipment checklist
If you want to use System 500 for
Static or Rapid-Static survey then the
minimum equipment you need is a
pair of System 500 units.
Each unit comprises a SR510 or
SR520 or SR530 sensor.
A single frequency SR510 sensor
requires an AT501 single frequency
antenna; SR520 and SR530 sensors
need to be connected to a dual-
frequency antenna, normally the
AT502 standard antenna or - for
utmost accuracy - high precision
chokering antennas: either a AT503
or AT504.
An antenna cable is needed to
connect the sensor and the antenna.
A TR500 terminal - a keyboard &
display device - is needed to easily
start the operation, check system
status and manipulate sensor
parameters.

Setting up System 500 for a Static survey
Setting up System 500 for a static survey
Connect the antenna to the sensor
using the antenna cable.
Plug two camcorder batteries into the
backside of the sensor. Alternatively
or in addition you might want to
power the sensor externally. In this
case connect a GEB71 battery to one
of the PWR- ports of the sensor.
Attach the TR500 terminal to the
sensor, either directly or via a
connection cable by plugging it into
the TERMINAL-port on the sensor.
Insert a PC-card into the sensor.
Warning
Lock the lid carefully after
insertion of the card in order
to prevent water and dust
from getting inside the
sensor.
Use the hook on the backside of the
sensor to hang it on one of the tri-pod
legs. Alternatively you may want to
leave the sensor inside the shipping
case.
Your System 500 sensor is now fully
ready for operation.
Successful GPS surveys require
undisturbed satellite signal reception.
This means that GPS sensors should
be set up in locations which are free
of obstructions. No obstacles like
trees, buildings, mountains, etc.
should block the line between the
GPS antenna and GPS satellites.
This holds true in particular for the
sensor which serves as the
reference.
For static and rapid static surveys,
the antenna must be kept perfectly
steady throughout the whole
occupation of a point. This means
that the AT501 or AT502 antenna will
usually be put on a tripod.
Center and level the tripod precisely
above the survey marker. Place and
lock the carrier in the tribrach. Mount
the antenna onto the carrier.

Static and Kinematic Surveys-2.0.0en Using the TR500 terminal
Using the TR500 terminal Menus
A typical example can be found in
the main menu:
You can see 7 different choices. Line
"1 Survey" is highlighted which
means that this is the currently
selected choice.
You can navigate up and down the
screen using the cursor up / down
keys on the terminal. The highlighted
bar will follow accordingly. For
instance press the "cursor down key"
twice to highlight "3 Applications":
The function keys at the bottom of the
screen describe certain commands. If
for instance you want to enter the
"Applications" part of the software you
press F1 CONT (to continue).
In order to operate System 500 some
interactions between the user and the
TR500 terminal are usually required.
You will find the operating concept of
the onboard software intuitive and
easy to use. All screens and panels
are steered in the same way which
makes the software very userfriendly
and easy to learn.
This chapter explains by use of some
examples how to operate the
terminal. These operational
guidelines apply to all parts of the
System 500 onboard software.
We basically distinguish between
menus and screens which require a
certain input.

Using the TR500 terminal
Menus, continued Entering information
A typical example can be found in
the main Survey panel:
Two inputs have to be made here, the
Point Id and the Antenna Height. Use
the cursor down / up keys to move to
the desired input field. In the current
example the Point Id can be entered.
Use the alphanumeric keys on the
terminal to enter the information.
Use the CE key to correct any typing
error.
Use the ENTER key to conclude the
input.
A shortcut is to press the numbers
which are associated with each
choice directly. For instance if you
press "6" you will get straight into
"Configure"
