Sokkia & GPSa solid and lastingrelationship

For decades, Sokkia has taken the lead in developing and marketing total surveying systems,

encompassing all phases of the job from the field to the processing and analysis in the office.

As one of the worlds foremost manufacturers of surveying equipment, Sokkia recognized thepotential of GPS already in the late 80s of the last century. Thanks to this early insight Sokkia

has developed into a major player in the GPS industry.

In 1991 Sokkia introduced a GPS receiver unique for its time, the

GSS1. Not much later it became clear that more benefit from GPS

technology would come from combining GPS and optical data.

This concept led to thefirst ever integration of GPS and ETS

observations in the most innovative survey field book of its time;

the SDR33, a milestone in surveying.

In the new century, Sokkia has continued its strive to provide

surveyors around the world with accurate, easy to use and reliable

GPS solutions. Over the last five years a number of new receivers

have been introduced, all of which have found a successful way into

the market. The newest in the line of Sokkia GPS receivers is the

GSR2700 IS; a high tech GPS receiver in which Sokkia has invested

all of its 85 years of innovation and creation. The GSR2700 ISfeatures: reliable RTK performance with high update rate & low

latency, wireless technologies for cable-free operation, integrated

data-link for radio and GSM/GPRS and a lightweight and rugged

design.

In order to further improve flexibility and productivity, Sokkia

has introduced the ultimate successor of the well known SDR33

controller software: SDR+. The uniform GPS-ETS operating

concept which Sokkia introduced back in the 90s has been

further improved and refined. SDR+ combines an intuitive

workflow, powerful data management, true coordinate system

flexibility and the most comprehensive editing capability on the

market today.

SDR+ is completely prepared to be the foundation for all surveying

needs in the coming decade, able to integrate whatever upcoming

new technology.

The combination of SDR+, the new GSR2700 IS GPS receiver and

any of Sokkias total stations will give surveying an extra boost of

accuracy, efficiency and flexibility!

SDR+Data collectionsoftware

A new era in GPS & ETS data collection

How to surpass the success of Sokkias SDR33, the unrivalled

data collector which was a revolution for surveying in the 90s?

Now Sokkia has the answer: SDR+. Keywords for SDR+ are: total

flexibility, total control and total freedom.

With its unique live database, SDR+ controller software defines

a new era in data-collection. It provides all possible flexibility in

collecting, viewing and editing your survey data.

Data management

This powerful data management makes SDR+ unique. The databaseis coordinating all observed points and checking the tolerances

constantly. When editing target details in, or adding new control

points to the database, SDR+ will check previous observations

automatically and will notify the user if there are points which breach

their tolerances. This real time observation checking functionality

is based on settings configured by the user. The user determines if

and when breaches in tolerance are reported as warnings or errors

depending on the application.

Customized workflow

All observations and relevant accompanying data are stored in one

job and can be reviewed as plan view or list of data. Simple operation

helps navigating through the data and all necessary details. All

frequently used options can be placed on the customizable toolbar.

Of course SDR+ offers the freedom to survey in any sequence.

The software allows customizing the workflow, project and application

settings and save them as a template for later use.

This makes it possible to observe backsights at any time and to

occupy coordinated points later in the survey. All of this independent

of what sensor is being used, total station or GPS.

All of this is presented in a modern and intuitive looking touch screen

interface with both text and graphic display.

Coordinate Systems

SDR+ offers endless possibilities to define custom coordinate

systems; projected, local grid or geographic. Creating custom

ellipsoids and datums; entering datum transformation parameters

and even defining relationships from one coordinate system to the

other is easier then ever. Once defined, they can be used throughout

all jobs and switches from one system to the other can be made

instantaneously.

Stake out

Simply load the design coordinates into the SDR+ database; Select

the point either from the Plan view or job list for stake out. User

definable thresholds will provide quick and easy guidance to the

location. A complete and easy to read stake out screen presents

information required for effective staking out the point.

Topography

Simply define a station setup and bother about the details later.

Back sights can be added at any time. The user decides whether

to include them in the coordination of points or not. Setting up a

RTK Base is not much different, SDR+ allows the user to enter

the definite control coordinates at any stage of the job. Multiple

ways of measuring offset points are available while original

observations are always kept in the database. At any point in

time the user can verify where your detail points are derived from.
