Ag Leader Technology

What is GPS?

consists of 24 orbital satellites that are used to determine positioning on earth. GPS receiver units, such as the GPS 2000/2100, use these satellites to provide position data as you harvest, thus helping to map your movements in the field.

What is DGPS?

allows your position to be calculated more accurately than with only GPS signals. DGPS signals can originate from varying sources.

One form of correction originates from Medium Frequency (MF) radiobeacons. These beacons are located worldwide, free, and are run by the Army Corps of Engineers and the Coast Guard in the United States. The GPS 2000 uses the free MF radiobeacon system for its DGPS.

Another form of correction can be obtained from satellites. This correction type requires a yearly subscription from a satellite correction provider. This method can provide a higher degree of accuracy in some coverage areas and allows for usage in areas not currently serviced by the MF radiobeacons. The GPS 2100 has the ability to use either of these methods of differential correction.

GPS 2000 Features

GPS 2100 Features

The GPS 2000 unit contains a combined twelve-channel GPS and

radiobeacon receiver board. It uses DSP, Digital Signal Processing, for the radiobeacon signals, and it tracks two beacons at all times. Trimble Navigation, the leading company making GPS receivers, manufactures the receiver board.

• The system has a Trimble combined GPS/DGPS antenna.

• The unit features a graphics display and keypad.

• The unit is programmable, which means it can be updated in the future

to meet the user’s needs.

The GPS 2100 has all the features listed above for the GPS 2000.

• Has the ability to also use satellite based differential correction.

• Choice between using either Omnistar or Racal to provide the

differential correction service.

GPS 2000/2100 Advantages over Other Systems

Ag Leader Technology

The GPS 2000/2100 systems are submeter class receivers, which means they can be extremely accurate under certain conditions as compared with lower-accuracy and cost systems. This accuracy allows the GPS 2000/2100 to provide accurate speed to the Yield Monitor 2000, thus eliminating the need for a radar gun and eliminating slip problems associated with wheel sensors.

The units can also store data in their 128K memory, which allows the user to take the units out in the field by themselves to mark points and boundaries. This is tied in with the ability to navigate back to marked points in the field, and to navigate to soil sampling sites.

The GPS 2100 adds the ability to use two different forms of differential correction in one unit. The user can choose to use either the free MF radiobeacons for corrections or subscribe to Omnistar or Racal satellite services to provide differential. This allows for total flexibility should problems arise with one source of differential or a MF radiobeacon is added in your area.

versatility and the ability to upgrade. Instead of being a single operation and use device the GPS 2000/2100 allow the user to put more precision into farming.

The antenna can be mounted on any metal surface, as long as the dome side of the antenna is pointing up towards the sky. To avoid noise problems from vehicle electrical systems, you may need to move the antenna around the vehicle until you find a suitable location. Finding a suitable location may require building a small stand for the antenna so that it can be placed an acceptable distance from interference.

After the system is securely mounted and all the wires are connected, turn the GPS 2000/2100 on.

Note: The unit may take a few minutes to orient itself and provide a lock on satellites and a differential source, then it is ready to run.

Soil Sampling

Using the GPS 2000/2100 the user has the capability to enter sample locations, navigate to these points, and then mark the site where the sample was taken. To transfer data to and from the GPS 2000/2100 the user will need to install the GPS 2000 Utilities program provided with the system. Refer to section 4, Software, to install the GPS Utilities program and general usage instructions.

The following is a description of how to collect soil samples using the GPS 2000/2100:

Step Action

1 Use a software program capable of griding fields to generate a

soil sample grid map.

2 Write down the LATITUDE & LONGITUDE for each point or

print out a copy of the locations. Also record the total number of samples that will be collected in the field.

3 The user must now create a new file with the desired sample

points in it. Follow the steps starting on 4-8 to create and save this file. The file created must be saved in the HEXASCII format before it can be transferred into the GPS 2000/2100.

4 From the main window of the GPS Utilities program, click on

the MEMORY button. Click on the TRANSFER TO GPS button. Select the file that was modified with the sample points and click OK. Follow the on screen instructions and place the GPS unit in LOAD MEM mode. The progress indicator in the lower right-hand corner of the screen will indicate that data is being transferred to the GPS unit.

5 The program will now prompt the user to put the GPS unit

back into LOAD MEM mode to complete the transfer. Once the unit is in the correct mode click OK. When completed the GPS unit will return to standard mode.

6 On the GPS 2000/2100, press the MARK key. Using the arrow

keys select a field that contains sample data. The screen should indicate the number of points that you entered. Press the SETUP key once and then press the F2 key to select the RESCALE function. A map of the points that were entered for the field should now be visible on the screen. Press SETUP again and press F4 to QUIT and return back to mark mode. The

map should still be visible.

7 Return to standard mode by pressing the RUN key and then

press the NAV key. Once again select a field that sample data was entered for. The latitude and longitude that were entered for the first sample site should now be shown on the screen.

8 The GPS 2000/2100 now has the locations of the sample sites

loaded into memory and is now ready to guide the user to the indicated sample sites and record the location that the samples are taken at.

9 Refer to the instructions on Mobile Applications, section 2-4,

to setup the GPS 2000/2100 for usage on a vehicle.

10 Once the user has the unit mounted and is ready to head for the

first sample point put the unit in navigation mode by pressing the NAV button.

11 Select the field that contains the sample sites and the distance

in two directions should be displayed. These distances refer to the direction and distance that the user must travel to reach the indicated location.

12 Once the point is reached, stop the vehicle and press the RUN

key to get back to standard mode.

13 The user has several options for recording the current location

of the samples:

Names each MARK (up to 32)

as a different sample point.

If the user… Then

From the standard mode, use the UP and DOWN arrow keys to scroll through the marks until the user sees the desired spot mark. Press the F key below the mark name to log that point. The GPS unit will now go into mark mode and make one mark. Press the RUN key to return to standard mode then the Nav key to continue to the next point.

Names each FIELD, (up to

255), as a different sample point.

From standard mode, press the MARK key and then select the field for logging. Turn logging on and off manually by moving the cursor to LOG and then use the UP or

14 Repeat steps 11-13 for each point until all the samples have

been collected.

The following steps describe an alternate method for taking soil

samples using the GPS 2000/2100:

Step Action

1 Use a software program capable of generating grid maps to

create soil sample sites.

2 Write each sample location down or print off a copy of the

latitude and longitudes.

3 Turn the GPS 2000/2100 on and place it in standard mode.

Press the MARK key.

4 Select a field that will not be used to log any other points in

when the sample locations are recorded. Press one of the F keys to make a mark. Return the GPS to standard mode by pressing the RUN key.

NOTE: The GPS unit must have data in it to be able to manually put coordinates in for navigation, thus the need for this step.

5 Go to the field where the samples will be collected. From the

standard mode of the GPS 2000/2100, press the NAV key.

6 Press the F1 key. A cursor should now be flashing on the first

number of the LAT: value.

7 Use the arrow keys to move the cursor to the right and adjusts

the values. As the user changes the values and the desired number is entered, the directional headings and distance to the point should update and indicate which direction and distance the user must travel to reach the sample site entered.

8 Once the user reaches a sample site follow steps 12-14 of the

previous instructions.

General Information

The time displayed is the time at the Prime Meridian. This time is useful mainly because the updating time indicates that the receiver is receiving new information.

The format for latitude and longitude readings is ddmm.mmmm. This reading will be different from that of the Yield Monitor 2000 because the yield monitor displays the values in a different format, which is dd.dddddd. (d=degrees, m=minutes). The PF3000 however, will use the same format as the GPS 2000/2100.

To maintain differential correction, the unit must receive a minimum SNR of 6.0 for radiobeacon differential. On average, the unit will run between 10 and 18 SNR, depending on your location in relation to a beacon. For satellite differential an SNR of 4.0 must be received. An acceptable range is 6 – 10.

Converting INTERNAL format to AL2000 or HEXASCII formats

If the user has downloaded data from the GPS 2000/2100 in the INTERNAL format then they have the option to convert this data into either the AL2000 format (to make maps) or HEXASCII format(to reload into the GPS). Follow these steps to convert the INTERNAL format:

Step Action

1 Start the GPS 2000 Utilities program. 2 Click on the MEMORY button. 3 Click on the EDIT GPS MEMORY FILE button. 4 The OPEN MEMORY FILE window is now open. Select the

file that will be converted and click OK.

5 The SELECT FIELD window now appears. Use the down

arrow to select a specific field to convert or select ALL to convert all the fields in the selected file. Click on OK once the selection is made.

6 The EDIT GPS RECORDS window is now visible. Click on

FILE. The user now has three save options; Save as AL2000, Save as INTERNAL, and Save as HEXASCII. Select the format that is desired and click on it.

7 The OPEN/SAVE AL2000 window appears. Click on OK to

accept the name the program gives the new file or enter in a custom name for the file.

8 Depending on which format is selected and the size of the file

the program will now process the data and return to the EDIT GPS RECORDS window when done.

Creating new data files

The user has the option to create a new data file that can then be loaded back into the GPS 2000/2100 and used for navigation or soil sampling.

The following steps describe the process of creating a new data file:

Step Action

1 Start the GPS 2000 Utilities program. 2 Click on the MEMORY button. 3 Click on the EDIT GPS MEMORY FILE button. 4 A question window will now appear. Click on YES to create a

of records that will be created. This refers to the number of soil sample that will be taken for example. Once a value has been entered click the OK button.

6 The EDIT GPS RECORDS window is now displayed. Double

click on a blank cell in the column and row that a value will be entered for. The EDIT RECORD X window will now be displayed. Enter in all appropriate values and then click the OK button. If the user has failed to enter in required values or only wished to enter in latitude and longitude values then the program will ask the user whether or not to fill in required information with a default value. This allows for quick and easy creation of data files.

7 After all the records to be entered have been created, click on

the FILE menu option and select one of the formats to save the file as.

Separating fields in the AL2000 format

When downloading files in the AL2000 format from the GPS 2000/2100 or converting from the INTERNAL format to AL2000 the user will more than likely have more than one field included in the file. When making maps the user would typically map each field separately. This can be accomplished by using a common spreadsheet program such as Excel or by using the utilities program.

The following describes how to create AL2000 ( .txt) files for a selected field out of a current file:

Step

Parts, Tools for Antenna Installation

Installing the Antenna Bracket

or any other vehicle the user should test the system in the planned installation location. Depending on what vehicle the user plans to mount the system, turn on all accessories or features of the vehicle that use electrical power, examples being lights, air-conditioning, etc. If the SNR drops below 8 or is lost completely, move the antenna to a location where the signal is not as effected by the interference. Moving the antenna horizontally or vertically between 1-3 feet will usually eliminate the problem.

NOTE: On combines such as the JD XX20 series, the antenna may need to be mounted on the back of the grain tank. The reception problems occur due to the location of the engine. Other models that have a side-mounted engine may also experience reception problems. Ag Leader Technology provides a 25-ft antenna cable for these installations if needed, contact Technical Support at (515) 232-5363 to get this cable if it was not included in your kit already.
