Topcon Overview

Topcon Positioning Systems, Inc., provides surveyors, engineers, construction contractors, and many others in similar fields with innovative positioning technology.

The Topcon hand-held devices, including the GMS-2, incorporate a graphical Windows operating system on a color touch-screen. It contains anything a hand-held GPS would need.

Product Overview

The GMS-2 is Topcon’s industry leading integrated imaging and 50-channel dual constellation satellite tracking small hand-held GPS receiver. This system incorporates an integrated electronic compass, replaceable/ rechargeable battery, and an expandable memory slot. The internal GMS-2 digital camera allows users to take digital photos of GIS features while in the field. The picture is automatically linked to the GIS feature and the photo itself can even be geo-tagged with the GPS coordinate.

IDENTIFICATION

The front of the GMS-2 is the primary interface with its components and installed software. The internal GPS antenna detects signals from GPS+ satellites and sends them to the GPS

receiver for processing.

The display screen and touch panel provides a graphical and tactile user interface for the unit.

The power button turns the receiver on and off.

The ESC (escape) button exits from the current screen or function. Pressing this button for one second or more opens the Microsoft Windows Start menu.

The ENT (enter) button applies settings, numerical values, and records points (depending on the setting of the internal software).

The charging LED indicates the level of charges in the battery: - Green: battery has a full charge - Red: Battery is charging - Red blinking: charging error

STEP by STEP

Turn on:

1. Press power button

Setup Job:

1. After turning unit on, double click the TopSURV icon 2. If there is not a TopSurv Icon, double click My Devices, then click on

the following icons: a. Flash Disk b. TPS c. TopSurv d. Scroll down to TopSurv icon and double click.

3. Open the jobs tab

Double-Click the TopSURV Shortcut using the stylus.

Select New to create a new job for data collection.

Page 8

4. Select New Job

5. Type the job’s name in the space provided with the pop up keyboard.

6. Enter the names of your team members and yourself in the “Created By” blank and click “Next”.

7. Set the GPS+ Config (GPS configurations) to WAAS DGPS, then click “Next”.

8. Set the Projections to the area you will be using the TOPCON GMS-2 (for the coastal job)

a. Set SP83 – Alabama (West)

9. Set Dantum to NAD83

10. Set Geoid to G2003U07, and then click next

11. Set the settings to your preference (suggested use):

a. Distance to US Feet b. Angle to DMS c. Coord Type (Coordinate Type) to Grid d. Coordinate order to Northing, Easting, Elevation e. Azimuth origin to North f. Disp Dir (Display Direction) to azimuth

12. To finish creating a new job click the finish button on the top of

the screen 13. Once steps 1 – 19 have been carried out, the unit will open a

screen with a main menu and title bar (which should contain the title of the job name you have just created). Similar to image on following page.

Page 9

14. To add different data codes and attributes, click Edit Job, then Codes.

15. The top panel is for codes, and the bottom panel is for attributes.

16. Click Add next to the top panel for additional codes, and the Add button next to the bottom panel for additional attributes.

17. If drop down menus are necessary for the attribute, ensure the

menu next to Type says Menu.

18. Once this is set, another panel will open where you should type the name next to Add and then click the Add button for each additional attribute for that code.

19. If the screen appears similar to the picture above, you may

proceed to the “Collecting Data Points” section below.

20. However, if the screen does not appear the same, try the steps once more.

Page 10

Collecting Points:

1. After selecting the proper job, select the “collect” icon

2. Then select the “collect feature” icon

3. Once you are in location to collect a point click the “code” drop down tab and select or type in (using pop up keyboard) the object you are recording

4. Select the feature or features (in the case of a cluster) being plotted. (ex. Fire Hydrant, Water valves, Sewer/Manhole, Electric Transformers and Gas Utilities).

5. On the top right of the screen, the H & V symbol will show the accuracy of the satellite signal at the current time.

a. Wait about 10 seconds before collecting a data point, so that these numbers will potentially get better.

b. The lower the number at the time of “Data Collection” the better the accuracy of the collection.

6. The color in the box next to the “H” MUST BE GREEN in order to collect data…

a. If it is RED you have a BAD signal. Wait a few minutes for it to get a better signal.

7. Place the GPS directly over the data point or as close to the object being plotted as possible, in order to get the most accurate readings possible.

8. Once the satellite strength is good (the color is GREEN and there is a LOW “H&V”), Select “Start” or Press the Blue ENT button to collect the data points.

Page 11

9. Now, find the next closest point, and continue collecting data.

10. Keep track of the items plotted on the notebook paper provided, in case of equipment malfunction.

a. To properly keep a paper copy of the points plotted, be sure to number each point made.

b. Write down the feature being plotted at each point.

Recovering Points:

1. Once you have selected the correct job click the “navigate” icon from the main screen.

2. Click “points” icon.

3. Enter what point # point you want to begin to recover.

4. Click the navigate button at the bottom right of the display screen.

5. Follow the compass arrow on the display screen to be lead to your point location (hint: at times it can be much easier to just use the horizontal distance to find our way to the point because the arrow can move around due to signal interruption)

Page 12

6. The arrow changes to a crosshair when you get within 10 feet of the

data point.

7. When you locate the data point, MARK the point with color marking tape and flags. The color of the tape can be determined by the list below: a. Fire Hydrant – BLUE

b. Water Valve – BLUE

c. Sewer/Manhole – GREEN

d. Electric Transformer – RED

e. Gas utilities – YELLOW

8. To find the next collected point click the right arrow () next to the store button

Page 13

9. Repeat steps above to recover all collected location points.

* For best results stay in open spaces away from covered areas and large buildings.

POTENTIAL PROBLEMS AND SOLUTIONS Warning: Do not attempt to repair technical equipment yourself, contact your Project Supervisor for any extreme problems with the GMS-2 hardware. Check This First!

If the software is not working, reset the software. To do this, see “Resetting the Software” below.

Check all external connections. Check all power sources. Is the battery drained or incorrectly

connected? Check to see that the software is current.

Resetting the Software The following steps can be used to reset the software, however: only attempt if you are competent to work on this device. To perform a software reset, use the stylus to push in the software reset button (see Figure 6-1, below).

Figure 6-1

Charging/Powering Problems If the GMS-2 does not power up… The batteries may be discharged.

o Connect the GMS-2 to a ground outlet. o Or if given an extra battery, insert the extra fully charged battery.

The charging cable may be disconnected or damaged. The GMS-2 may have a defective charger or defective internal battery.

o If, after charging the battery, the GMS-2 still does not power up, you must get a new battery.

GMS-2 Problems The following are just a few of the problems that most commonly are encountered while working with the GMS-2. The GMS-2 is not finding the satellite signal to collect the data point. There may be a structure (such as a building) deterring the GPS unit

from connecting with satellites. Try to face a different direction in order to potentially connect with another satellite and move away from the tall structure.

If there is cloudy weather, it may take longer to retrieve data points and gain satellite signals. BE PATIENT!!!

If neither of the above are the case, and your GMS-2 will still not connect to a satellite, contact your Project Supervisor.

Installed software and other data have been erased. The battery in the GMS-2 has been completely drained or a hardware

reset has been unintentionally preformed. o Reinstall all software. Contact the Project Supervisor to do this!
