1. IntroductionFor decades, Leica Geosystems has enjoyed a worldwide technological lead in the manufacture of classical surveying instruments and systems. Starting in 1987, Leica Geosystems established a close business relationship with Magnavox's commercial GPS business unit for the design and construction of GPS surveying sensors. This culmi-nated into Leica Geosystems acquisition of the Magnavox GPS business unit in 1994. With this purchase, the unbroken chain of impressive "firsts" now incorporated the field of satellite navigation and positioning technology. Magnavox was one of the first pioneers in this arena, playing a leading role in the development of GPS and its predecessors. Further acquisition of the Philips Ap Navi-gator business in 1997 widened Leica Geosystems product palette to an even greater extent.

In May 1999, Leica Geosystems entered the GIS/GPS data collection market with the introduction of the Leica Geosystems GS50 GPS sensor and Leica Geosystems GIS DataPRO office software. With the integration of ERDAS and LH Systems in 2001, Leica Geosystems has expanded its product areas to offer four ranges of GIS and mapping solutions - airborne data acquisition, geographic imaging, GPS/GIS, and land information systems. Leica Geosystems' airborne sensors, field data collectors, work-stations and software help customers create and update GIS databases rapidly, accurately and cost effectively. Leica Geosystems is the first choice for geographic data acquisition systems, 2D and 3D image processing and visualization, and mapping solutions.

Description of the System Leica Geosystems GS20 User Manual-2.0.0en 10

Charge the BatteriesYour Leica Geosystems GS20 is powered by a recharge-able 7.2 V, Li-Ion battery. The battery can be charged and discharged hundreds of times but it will eventually wear out. When the operation time is noticeably shorter than normal, it is time to buy a new Leica Geosystems GEB90 Li-Ion Battery. One battery, fully charged, will power the GS20 for about 7 hours continuously. Operating times will be shorter when working in cold weather.

Primary use/charging• The battery must be charged prior to using it for the first

time because it is delivered with an energy content as low as possible.

• For new batteries or batteries that have been stored for a long time (> three months), it is effectual to make only one charge/discharge cycle.

• For Li-Ion batteries, a single discharging and charging cycle is sufficient. We recommend carrying out the process when the battery capacity indicated on the charger or on a Leica Geosystems product deviates significantly from the actual battery capacity available.

• The permissible temperature range for charging is between 0°C to +40°C/ +32°F to +104°F. For optimal charging we recommend charging the batteries at a low ambient temperature of +10°C to +20°C/+50°F to +68°F if possible.

• It is normal for the battery to become warm during charging. Using the chargers recommended by Leica Geosystems, it is not possible to charge the battery if the temperature is too high.

Operation/Discharging• The batteries can be operated from -20°C to +55°C/

-4°F to +131°F.• Low operating temperatures reduce the capacity that

can be drawn; very high operating temperatures reduce the service life of the battery.

Powering Up the UnitThe GS20 operates on a single battery. Once a battery is fully charged, you are ready to power up the GS20.

1. Open the GS20 Battery door by turning the door latch 90 degrees counterclockwise, and pull open the battery door.

2. Place the battery in the well with the gold contacts facing down and making contact.

3. Shut the battery door and return the latch to the locked position, with the spin arrow facing upward toward the dot on the housing.

4. On the keypad, depress the Power Button in the Lower Left corner, just left of the 0 key. Startup will be followed by an audible tone, then after a memory check (2 to 3 seconds) the GS20 Splash Screen will be followed by the Main Menu.

5. Once the Main Menu appears, the receiver will begin to search and acquire satellites.

Make sure that the GS20 has a clear view of the sky!

Initially the GPS unit will not have an Almanac (The almanac is a library of satellite orbits, that helps the GPS locate the satellites more quickly). When using the unit for the first time, or after a long period without use, it may take several minutes to acquire a position; this is known as a “Cold Start”.

Please refer to the GS20 Field Guide for information on basic functions and getting started with collecting data.


GS20 with the WoRCSIf you purchased the Leica Geosystems GS20 with the Wireless real-time Correction System, the WoRCS, you are only steps away from collecting real-time sub-meter data. The WoRCS comes pre-configured with the Blue-tooth linked to your GS20.

Leica GIS Data HandlerThe Leica GIS Data Handler interface is new to GIS DataPRO 3.0 and is an explorer style interface for sensor transfer. The GIS Data Handler interface is accessed by selecting Sensor Transfer from the Tools Menu, available on the main GIS DataPRO 3.0 toolbar, and can also be run as a standalone application.

The standalone application may be accessed from START>LEICA GIS DATAPRO>GIS DataHandler.

The GIS DataHandler provides a new interface and many improvements to the former Sensor Transfer functionality.


Installation of the USB Bluetooth ModuleNote that USB is not compatible with Windows NT.

Installation of the USB Bluetooth Module for data transfer between the GS20 and GIS DataPRO is only for the initial setup and will not have to be repeated. It is necessary to load GIS DataPRO 3.0 or higher to take advantage of the new GIS Data Handler support. This document will address new functionality and does not apply to GIS DataPRO 2.1 build 274. Please install GIS DataPRO 3.0 now, if it is not already.

After GIS DataPRO is installed, follow these steps:1. Plug in the USB Bluetooth Module. Windows will bring

up a "Found New Hardware" dialogue.

2. Windows will then ask for the location of the Device Driver (SiW).

3. The driver we are looking for is SS1BTUSB.SYS and may be found in the /ProgramFiles/Leica Geosystems/GISDataPRO directory; select Browse to find the file. (The file is also available on the GIS DataPRO 3.0 installation CD.)

4. Install using the Leica driver, "SS1BTUSB.SYS".

Once you have the Bluetooth driver installed, we are now ready to configure the virtual port.


Setting Up the Virtual Port and BluetoothTo communicate with the GS20 via Bluetooth we must configure a virtual COM port and enable Bluetooth commu-nication. To configure the virtual port, we will need to open GIS DataPRO.1. Open GIS DataPRO and select TOOLS>Sensor

Transfer from the main toolbar. This will load the new GIS DataHandler interface.

2. In the dialog, highlight SENSORS icon near the bottom of the directory tree on the left. Right click on Sensors and select "Setup Bluetooth."

3. This will open the Setup Bluetooth dialogue.

4. In the setup bluetooth dialogue, an empty "Virtual COM port" choicelist indicates that no virtual COM port has been setup yet. To set one up click the select "Setup Vcom" button.


5. In the Setup Virtual Com dialogue select the "Find Next Available Port" button.

Note that GIS DataPRO 3.0 will auto-search ports 5 to 10.

6. This will report back the next available com port. Click the Configure Button to accept the COM setting.

7. Now, with a Virtual COM port configured, select the "Setup Bluetooth" button from the Setup Bluetooth Dialogue. GIS DataPRO will then instruct you to go into the GS20 and perform the bluetooth inquiry.

Within the GS20, select from the main menu:

8. Setup> Hardware Management>Wireless>Blue-tooth>Sensor Transfer and Inquire.

9. The GS20 will search for Bluetooth devices in the area and return a list of alphanumeric addresses for the Bluetooth devices. Check that the selected number matches the Bluetooth dongle attached to your computer. If not, select the correct device from the choicelist.

10.At this point, you will need to select MENU and SAVE to save the address.

GIS DataPRO and the GS20 are now prepared to commu-nicate by Bluetooth. You can now close the Setup Blue-tooth Dialogue.


Adding the Sensor to Transfer DataTo use the Data Handler interface transfer data between the GPS sensor and your computer, the GPS sensor must be added to the directory tree of the software

1. From the main menu of the GS20 go to Utilities>Sensor Transfer

2. Ensure that the "Port" selected is the one you want to use to communicate, either Bluetooth or port 1 for a serial cable. (If you change ports, click "apply" to set the change)

3. In the software, highlight the SENSORS icon near the bottom of the directory tree on the left, right click and select ADD SENSOR. This will open the SENSORS dialogue.

4. Check that displayed in the SENSORS dialogue is the configured Virtual Port or serial port you are using. Select OK.

GIS DataPRO will read the connected device. You will see progress bars followed by the appearance of the GPS sensor icon with "System" and "PC card" sub-folders.


Leica Objects Versus Files and FoldersIn the Data Handler interface, the contents of the directory tree can be viewed in one of two ways. By default, the data is viewed as Leica objects, but it can also be viewed as normal files and folders. For example, compare the contents of the GeoDB directory of this GIS DataPRO job. When viewed as a Leica object, the job is a single icon.

When viewed as files and folders, the files that comprise a Leica Job are visible.

In Sensor Transfer, we can transfer various Leica file types to and from the GPS sensor, including:

1. GPS Jobs2. Antenna files.3. Configuration Sets.4. WAAS Satellite Lists.5. Geoid Field Files.6. GS20 Background Graphics.


Transferring and Importing GPS Job DataWith GIS DataPRO 3.0 and the DataHandler interface, it is now possible to Transfer Collected GPS data and Import the data directly into the Current DataPRO project. Once the sensor has been added to the Sensor Transfer dialog you are ready to import your job.

To transfer Job data from the sensor and import it directly to your current GDP project, do the following …

1. In the jobs directory of the PC-card of your sensor, right-click on the job you'd like to import.

2. Select "Import to Current Project" from the menu3. A dialog will confirm that you want the job files placed in

the Raw Data directory of your current project. Click "OK".

After transferring the raw data to your project directory the software will automatically generate shapefiles and add the data to your current DataPRO project.


Transferring Data FROM the SensorTo transfer data from your GPS sensor to your computer, select the Leica object from the directory tree of the sensor, right-click on it, and select Send To…

This will open the Transfer Files Dialogue. A browse button is available to place files in the location of your choice.

Transferring Data TO the SensorTo transfer data to your GPS from your computer, navigate to the file in the Directory Tree. Right-Click on the object and select Send To…

The PC Card options in this dialog supports the transferring of data to the Sensor's flash memory card when it's plugged directly into the PC.


Transferring Multiple Files and Firmware files to the SensorIn some cases you may want to transfer several files to the GPS sensor at the same time. In the case of a GS20 firmware upgrade there are several separate files that need to be uploaded. A dialog is available to support sending multiple to the sensor. To transfer multiple files from the PC to the GPS sensor do the following…

1. In the directory tree navigate to the folder containing the target files.

2. Right-Click on the object and select Send Files. The "Send Files" dialogue will open.

3. Check the files you want to send.4. Identify the "File Type" of the files you want to send.

(Note: You can only send one type of file at a time. For firmware files there are several different file suffixes including; .znc, .bin, .doc, and .jpg, but they are all part of the "Firmware" type and should be sent at the same time.)

5. Ensure the correct COM Port is selected.6. Click "OK".


The files will be sent to the unit and placed in the appro-priate directories based on the type of file you sent.

Drag and DropGIS DataHandler allows the user to drag and drop data to and from the GPS sensor and the connected PC. The drag and drop functions will bring up the same dialogs as the "Send" menu options.

Simply select the file of interest, and drag the data into a folder elsewhere in the directory tree. This will transfer the file.

In the case of GPS jobs dragged to GIS DataPRO, project directories will be added to that project.

Direct Creation of ShapefilesThe DataHandler interface also allows the direct creation of shapefiles from raw GPS Job data without having to bring the data into a GIS DataPRO project, and will support the creation of both standard and 3D shapefiles.

In order to create a shapefile directly:1. First, the data must

be transferred from the GPS Sensor to your PC. Transfer the GPS job data from the sensor to the directory of your choice.

2. Navigate the direc-tory tree to the GPS job you just trans-ferred, right click on the job and select Convert to Shape-files.


3. This will open the Export Shapefiles dialogue and the user will then select 2D or 3D shapefile. The user also has the option of accepting the default path to which to write the shapefile, or navigate to a new directory by clicking the browse button.

• To prevent damages due to indirect lightning strikes (voltage spikes) cables (antenna, power source, modem, ...) should be protected with appropriate protection elements (lightning arrestor). These installa-tions must be carried out by an authorized, local specialist.

• Additional protection against lightning: If there is a risk of a thunderstorm, or if the equipment is to remain unused and unattended for a long period, protect your product additionally by unplugging all systems components and disconnecting all connecting cables and supply cables (e.g. Receiver - Antenna).


Suggestion for design of a Lightning Conductor for a GPS System

1. On non-metallic structuresProtection by Air Terminals is recommended. An Air Terminal is a pointed solid or tubular rod of conducting material with proper mounting and connection to a conductor. The position of 4 Air Terminals should be uniformly distributed around the Antenna at a distance equal to the height of the Air Terminal. The Air Terminal diameter should be 12mm for copper or 15mm for aluminium. The height of the Air Terminals should be 25 to 50cm. All Air Terminals should be connected to the down conductors. The diameter of the Air Terminal should be kept to a minimum to reduce GPS signal shading.

2. On metallic structuresProtection is as described for non-metallic structures, but the Air Terminals can be connected directly to the conducting structure without the need for down conduc-tors.
