7 GPS 2000/2100 Introduction What is GPS? GPS is the acronym for Global Positioning System. The GPS system 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? DGPS is the acronym for Differential GPS. This is a correction system that 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 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. GPS 2100 Features The GPS 2100 has all the features listed above for the GPS Has the ability to also use satellite based differential correction. Choice between using either Omnistar or Racal to provide the differential correction service. April

8 Introduction GPS 2000/2100 GPS 2000/2100 Advantages over Other Systems 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. The primary difference between these units and others on the market is 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. * * * April

9 GPS 2000/2100 Setup Overview The GPS 2000/2100 system can be used for various functions. This section covers a few possible applications, but it is not comprehensive because the user may discover applications that has not attempted or tested. Initial Setup The following provides information on GPS 2000/2100 factory settings: Operation Beacon selection Satellite selection Setting The GPS 2000/2100 is set in Auto range mode. This normally is acceptable, but if the user prefers to set the receiver to a particular beacon, do the following: 1 Set the unit in standard mode. Note: Standard mode refers to the screen that the GPS 2000/2100 starts up in after the power has been turned on. This is the default screen. 2 Press the SETUP key until BEAC OPT is above F3. Press F3. 3 Press F3 again to place the unit in Manual mode. 4 Set the desired beacon frequency. Refer to section 3, Operation, for more information about making this change. This option is available on the GPS 2100 only. If you will be using the satellite differential option then do the following depending on which service provider you select: 1 Set the unit in standard mode. 2 Press the SETUP key until SAT OPT is above the F2 key. Press F2. 3 Press F1 to select Satellite differential. 4 If you will be Then using. OMNISTAR Service Press the F2 key to select the SAT SOURCE: that covers your usage area best. Call the OMNISTAR subscription number Apri

Key the code in to the right of OMNISTAR CODE: using the arrow keys. Once the code is entered press the F3 key to send the code to the GPS board inside the unit. Now press the F4 key to quit this screen and return to standard mode. Let the receiver run for at least 30 minutes, after which the receiver should start receiving corrections and display DIFF ON Press the F2 key to select the SAT SOURCE: that covers the usage area best. Call the RACAL subscription number provided and give them the number that is displayed to the right of GPS SERIAL#. RACAL will then activate a code for the serial number that was given. After the serial number has been called in, press the ENTER key to return to standard mode and wait for DIFF: to change from OFF to ON. Within minutes the receiver should start receiving corrections from RACAL. April

11 GPS 2000/2100 NMEA message selection Changing field, data type, and mark names Setup The GPS 2000/2100 has only the GGA NMEA string turned on initially. It is the only message string that the Yield Monitor 2000 needs for position data. If the user wants to use the GPS 2000/2100 to provide speed to the Yield Monitor 2000 or display speed on the GPS 2000/2100 itself, then the VTG message must also be turned on. Depending on the proposed use of the GPS 2000/2100, other messages may need to be turned on. See section 3-21 for more information on changing the NMEA strings that are output. The user can either change these names on the receiver or use the GPS 2000/2100 Utilities program provided with the system to enter the desired names. Refer to sections 3 and 4, Operation and Software, for a description of this process. Harvest Follow these steps to set up the receiver for harvest operation: 1 Attach the 10-foot coaxial cable inside the cab to the cable connection on the receiver. Important: Make sure the y-cable connecting the yield monitor and the receiver is securely connected, and the two connectors attached to the receiver are connected to the indicated ports. 2 Turn on the receiver. Result: After a few seconds various types of information should appear on the screen. After the unit becomes oriented, it will indicate a number of satellites and whether it is receiving a differential signal. Note: The screen may take a few minutes to display data because the unit must adjust to its location and acquire a good lock on satellites and a differential source. 3 Verify whether the yield monitor is receiving data from the receiver: a) Turn the yield monitor on. b) Under the yield monitor SETUP key, make sure that a memory card has been detected. See the Yield Monitor 2000 manual for more information on setting up the yield monitor to log GPS Apri

12 Operation GPS 2000/2100 data. c) Select the desired logging interval. d) Go to the field and load into which you will be putting data. Result: An upper-case D and G should be in the top right corner of the screen on the yield monitor, which indicates that you have GPS and differential signal from the receiver. You are now ready to harvest. Note: The marking functions can be used while harvesting, but keep in mind that any marks made with the GPS 2000/2100 while harvesting are not stored on the memory card. They are stored only in the GPS 2000/2100 s memory and will not show up on the yield map, but on a separate map downloaded from the GPS. Mobile Applications The GPS 2000/2100 system was designed to provide a great deal of versatility for alternative applications. The only limitations to usage are availability of power and a secure mount for the antenna. The appropriate power cable for the GPS 2000/2100 depends on the type of vehicle you are using: If you are... Then use... In a vehicle that has a The GPS cigarette power cable. cigarette lighter, On an all-terrain vehicle The GPS ATV/tractor power cable. (ATV) or tractor, Mount the GPS 2000/2100-display unit in a location that is secure and clear of interference from moving parts. The provided U-bracket may suit this requirement best. 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. April

13 GPS 2000/2100 Setup 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: 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/ 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 Apri

14 Operation GPS 2000/2100 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: If the user Names each MARK (up to 32) as a different sample point. Names each FIELD, (up to 255), as a different sample point. 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. 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 April

15 GPS 2000/2100 Setup DOWN arrows to turn logging ON and OFF. Or use a mark above the F keys to log one point to the field. Press the Run key and then the Nav key to continue to the next point. Now change to the next field to represent the next sample point. 14 Repeat steps 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: 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 of the previous instructions. Apri

16 Operation GPS 2000/ After the site is marked return to navigation mode and enter the next site to navigate to. Navigation mode will continue to only allow the user to enter in manual location values until the user presses the enter key. 10 Repeat steps 7-9 until all the sample sites have been logged. Site Verification For site verification, the unit most likely will be mounted on a tractor. If this is the case, the GPS 2000/2100 can be powered with the supplied GPS ATV/tractor power cable or the GPS cigarette lighter cable. The following steps represent the recommended method to operate the unit for site verification: 1 Place the GPS 2000/2100 in MARK mode by pressing the MARK key. 2 Use the directional arrow keys to select the field that data will be logged in. If a field name has not been entered the user has the option to manually key the name in by going to EDIT FLD which can be found from the standard mode using the setup key. Or the user can use the GPS Utilities program to enter in custom names (refer to 4-3). If the user wants to change the data type to be used they must create or edit the name using the Utilities program and then select that data type for the desired field using the EDIT FLD option. 3 The user must now decide how they will differentiate the data that will be collected in the field. It is recommended to use the available 32 marks to distinguish differences in a field. An example would be to name the marks on the basis of the different hybrids that will be planted. 4 Now select a logging interval (INT:) which is located on the MARK screen. Use the directional arrow keys to select a logging interval that will provide enough memory to complete a desired amount of work. NOTE: If you use a logging interval greater than 3 you will need edit it back to 1, 2 or 3 sec. using Excel 5 After all the names have been entered and the field that data will be logged in is selected, the user has two options for logging. Set LOG: to ON by moving the cursor to LOG and use the up, down arrow keys to turn logging on and off. Then activate either spot or continuous marks as needed. Or Activate a continuous mark and also use spot marks. April

17 GPS 2000/2100 Setup Note: To activate a continuous mark press the MARK key followed by the appropriate mark. To activate a spot mark, press the appropriate F key Either method is valid but the first option will provide maps with greater detail and less gaps. For more information on editing names and logging data see sections 3 and 4, Operation and Software. Collecting Site Verification Data on a Memory Card Another possible configuration is to use the Yield Monitor 2000 to collect the site verification data on a memory card, which allows the user to name fields and loads like the Yield Monitor does during harvest. Follow the setup steps above under Collecting Data, but note that the GPS 2000/2100 is not used to log the data. Refer to the Yield Monitor 2000 manual for more instructions on this procedure. * * * Apri
